Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to serious

consequences.

Observe the precautions of both levels because they are important for personal and system safety.

Make sure that the end users read this manual and then keep the manual in a safe place for future reference.

[Design Precautions]

WARNING

● When the safety remote I/O module detects an error in an external power supply or a failure in the
odule, it turns off the outputs. Configure an external circuit to ensure that the power source of

m

azard is shut off by turning off the outputs. Failure to do so may result in an accident due t

h
i

ncorrect output or malfunction.

● When a load current exceeding the rated current or an overcurrent caused by a load short-circuit

flows, the safety remote I/O module defines it as a fault and turns off the outputs. Note that if the

vercurrent state continues for a long time, it may cause smoke and fire. To prevent this, configure a

o

ternal safety circuit, such as a fuse.

ex

● At the start-up of the system, if the load power supply is short-circuited by the output wiring of t

sa

fety remote I/O module, a load may turn on just after the power-on. Configure an interlock circuit to

ensure that the entire system will always operate safely.

● When a communication failure occurs in the network, data in the master module are held. Check Dat

ink status (each station) (SW00B0 to SW00B7) and configure an interlock circuit in the program t

l
e

nsure that the entire system will operate safely.

● When a communication failure occurs in the network, the failed station becomes the following status

Check the communication status information and configure an interlock circuit in the program to
ensure that the entire system will operate safely. Failure to do so may result in an accident due t

ncorrect output or malfunction.

i
(1) All inputs from remote I/O stations are turned off.
(2) All outputs from remote I/O stations are turned off.

● Do not use any "use prohibited" signals as a safety remote I/O signal and a remote control/monitor

signal since they are used by the system. If any of the "use prohibited" signals are used (turned on or
off), the correct operation of the module cannot be guaranteed.

● Do not read/write data from/to the remote register since all areas of the remote register are "u

p

rohibited" areas. If data is read or written from/to the remote register, correct operation of the modul

cannot be guaranteed.

[Design Precautions]

CAUTION

● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.

● Select the external devices to be connected to the module by referring to the performance
specifications in this manual and considering the maximum inrush current. Connecting a device
exceeding the maximum inrush current may cause malfunction or failure of the module.

● During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.

[Installation Precautions]

WARNING

● Shut off the load power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.

[Installation Precautions]

CAUTION

● Use the module in an environment that meets the general specifications in this manual. Failure to do
so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.

● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.

● Securely fix the module with mounting screws. Failure to do so may cause the module to fail due to
increasing effects of vibrations.

● Securely connect the cable connectors. Poor contact may cause malfunction.

● After the first use of the product, do not connect/remove the connectors more than 50 times (IEC

61131-2/JIS B 3502 compliant). Exceeding the limit may cause malfunction.

[Wiring Precautions]

WARNING

● Shut off the load power supply (all phases) used in the system before wiring. Failure to do so may
result in electric shock or cause the module to fail or malfunction.

3

[Wiring Precautions]

CAUTION

● Individually ground the FG metal fitting of the programmable controller with a ground resistance of 100
ohms or less. Failure to do so may result in electric shock or malfunction.

● Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire
or failure.

● Tighten the waterproof caps within the specified torque range. Undertightening can cause short
circuit, fire, or malfunction. Overtightening can damage the waterproof cap, resulting in short circuit or
malfunction.

● The module meets IP67 only when all of the waterproof plugs and waterproof caps are attached and
the cover of the station number setting switch is securely fixed with a screw.

● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.

● Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.

● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.

● When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable
with connector, hold the connector part of the cable. Pulling the cable connected to the module may
result in malfunction or damage to the module or cable.

● When an overcurrent caused by an error of an external device or a failure of the programmable
controller flows for a long time, it may cause smoke and fire. To prevent this, configure an external
safety circuit, such as a fuse.

● Wiring and replacement of a module must be performed by qualified maintenance personnel with

(1)

Wiring the power supply

When wiring the power supply, connect it to the POWER IN terminal of the power supply connector of the safety remote I/O

module.

Transition wiring of the power supply

When installing multiple safety remote I/O modules, the power can be supplied to the modules through transition wiring.

For transition wiring, connect wires between the POWER OUT terminal of the safety remote I/O module that will be the power

supplier and the POWER IN terminal of another safety remote I/O module that will be a power supply destination.

*1 The largest current flows from the power supplier to the power supply connector of the first safety remote I/O module. Make sure that the

current does not exceed the current capacity (8A/pin) of the power supply connector. For a power supply to supply 24VDC, use a power
supply (SELV power supply) that does not exceed 30VAC (effective value), 42.4V (peak value), or 60VDC. Also, use a power supply
which is applied to "limited-energy circuit" defined in IEC61010-1.

7.1 Input Function

Input ON delay, input OFF delay functions

Ex.

Ex.

This function changes an input signal when a predetermined time has passed after an actual input change.

A delay time can be set for each input change pattern, OFF to ON or ON to OFF. In addition, the function prevents incorrect

inputs caused by noise since a pulse of a certain time length is not taken in a module.

Input ON delay

The ON delay is the minimum ON time of the actual input signal required before the safety input signal changes from OFF to

ON.

When 5ms is set, the safety input signal turns to ON after the actual input signal is ON for at least 5ms.

Input OFF delay

The OFF delay is the minimum OFF time of the actual input signal required before the safety input signal changes from ON to

OFF.

When 5ms is set, the safety input signal turns to OFF after the actual input signal is OFF for at least 5ms.

Setting procedure

The "Input ON delay" and "Input OFF delay" times can be set from the "Parameter Processing of Slave Station" window of the

engineering tool.

The setting range is 0 to 1000ms (in 1ms steps)

The default value is 5ms.

• When "Wiring selection of input" is set to "1: Double wiring (NC/NC)" or "2: Double wiring (NC/NO), set the

same value as Xn+1 for Xn (n: even number).

• When "Input mode setting" is set to "1: Not used", this parameter will be ignored.

• In addition to this setting value, the safety refresh response processing time and the hardware response

time are also added as delay time for safety input signal switching. (Safety refresh response processing

• Write the safety communication setting to the Safety CPU after completing "Parameter write" to all safety

remote I/O modules connected. Failure to do so may cause an error (parameter mismatch of Safety CPU

and safety remote I/O module) in the Safety CPU at the restart of the safety remote I/O module.

• No restrictions are provided on the access level for writing parameters to the safety remote I/O module.

However, when the access level is "Users", even though parameters have been set to the safety remote I/O

module, safety communications are disabled because the safety communication setting cannot be set in the

Safety CPU. To perform the safety communications, set the setting with "Developers" or a higher access

level. For details on the access levels, refer to the following.

8.1 Module Parameter Setting of the Master Station

The following parameters are required to use the safety remote I/O module. The parameters are automatically set when a

safety remote I/O module is added in the "Network Configuration Settings". Change the start number and end number of the

RX/RY Setting or RWw/RWr Setting as necessary.

Item Description

STA# Set the station number of the safety remote I/O module.

Station Type Set "Remote Device Station".

RX/RY Setting Points 80 points

RWw/RWr Setting Points 16 points

• When using the safety remote I/O module, always enable "Station-based Block Data Assurance" of the

master station. When it is disabled, correct operation of the safety remote I/O module cannot be

guaranteed. For the station-based block data assurance, refer to the following.

 MELSEC iQ-R CC-Link IE Field Network User's Manual (Application)
 MELSEC iQ-R Simple Motion Module User's Manual (Network)

• Do not set the module parameters using the CCPASET instruction in the master station. Correct operation

of the safety remote I/O module cannot be guaranteed because the module operates with the Station-based

Block Data Assurance disabled when the CCPASET instruction is executed.

• Even though the number of points in the RX/RY Setting or RWw/RWr Setting and that in a safety remote I/O

module differ, an error does not occur on the module. For example, when the number of points in the RX/RY

Setting is set to 16 in a configuration with a safety remote I/O module, only the first 16 points are refreshed.

3. When the resistor (R) is 5.6 k, the power capacity (W) of the resistor (R) becomes 0.125W.

4. Because the resistor requires the power capacity of 3 to 5 times as large as the actual current consumption, the resistor

connected to the terminal should be 5.6 k, and 0.5 to 0.75W.

5. OFF voltage when the resistor (R) is connected becomes 4.67V. This satisfies the condition that the OFF voltage of the

safety remote I/O module must be 5V or lower.

A signal incorrectly inputs data

■Cause

Noise is taken as input data.

■Action

• Set a long input ON/OFF delay.

1ms  5ms

For the setting procedure, refer to the following.

If the above change has no effect, take the following two measures:

• To prevent excessive noise, avoid installing power cables together with I/O cables.

• Connect surge absorbers to noise-generating devices such as relays and conductors using the same power supply or take

other noise reduction measures.

the ERR. LED of the module and the error history. If
an error has occurred, eliminate the cause.

• If the same error occurs again even after "Safety
module validation" is executed in no error state, the
module may be in failure. Please consult your local
Mitsubishi representative.

• Review the connected devices, wiring, and voltage.

• Correct the module parameter settings and module
configuration.

• When the parameters are set again and the
parameter setting has succeeded, the module will
recover from this error.

*1 Detailed information of the error is stored in Error code details in Error history data. For Error code details, refer to the following.
