taken if there is danger of electric shock, fire, etc., which could result in loss of life or injury.

: This mark indicates that if these precautions

and operating procedures are not taken, damage to the instrument may result.

: This mark indicates that all precautions should

be taken for safe usage.

: This mark indicates important information on

installation, handling and operating procedures.

: This mark indicates supplemental information

on installation, handling and operating procedures.

: This mark indicates where additional

information may be located.

 An external protection device must be installed if

failure of this instrument could result in damage to the instrument, equipment or injury to personnel.

 All wiring must be completed before power is turned

on to prevent electric shock, fire or damage to instrument and equipment.

 This instrument must be used in accordance with the

specifications to prevent fire or damage to instrument and equipment.

 This instrument is not intended for use in locations

subject to flammable or explosive gases.

 Do not touch high-voltage connections such as

power supply terminals, etc. to avoid electric shock.

 RKC is not responsible if this instrument is repaired,

modified or disassembled by other than factory-approved personnel. Malfunction can occur and warranty is void under these conditions.

 This is a Class A instrument. In a domestic environment,

this instrument may cause radio interference, in which case the user may be required to take adequate measures.

 This instrument is protected from electric shock by

reinforced insulation. Provide reinforced insulation between the wire for the input signal and the wires for instrument power supply, source of power and loads.

 Be sure to provide an appropriate surge control circuit

respectively for the following:

− If input/output or signal lines within the building are longer than 30 meters.

− If input/output or signal lines leave the building, regardless the length.

 This instrument is designed for installation in an enclosed

instrumentation panel. All high-voltage connections such as power supply terminals must be enclosed in the instrumentation panel to avoid electric shock by operating personnel.

 All precautions described in this manual should be taken

to avoid damage to the instrument or equipment.

 All wiring must be in accordance with local codes and

regulations.

 All wiring must be completed before power is turned on to

prevent electric shock, instrument failure, or incorrect action. The power must be turned off before repairing work for input break and output failure including replacement of sensor, contactor or SSR, and all wiring must be completed before power is turned on again.

 To prevent instrument damage or failure, protect the

power line and the input/output lines from high currents with a protection device such as fuse, circuit breaker, etc.

 Prevent metal fragments or lead wire scraps from falling

inside instrument case to avoid electric shock, fire or malfunction.

 Tighten each terminal screw to the specified torque found

in the manual to avoid electric shock, fire or malfunction.

 For proper operation of this instrument, provide adequate

ventilation for heat dispensation.

 Do not connect wires to unused terminals as this will

interfere with proper operation of the instrument.

 Turn off the power supply before cleaning the instrument.  Do not use a volatile solvent such as paint thinner to

clean the instrument. Deformation or discoloration will occur. Use a soft, dry cloth to remove stains from the instrument.

 To avoid damage to instrument display, do not rub with

an abrasive material or push front panel with a hard object.

 Do not connect modular connectors to telephone line.

1. OUTLINE

One temperature control (TIO) module [extension type] enables temperature control corresponding to two channels. As the temperature control (TIO) module [extension type] is not provided with terminals for power supply and host communication, it is always used together with the module (temperature control module [basic type] X-TIO-A, etc.) with terminals for power supply and host communication. The temperature control (TIO) module [extension type] can be connected with the temperature control (TIO) module [basic type], the temperature control (TIO) module for PLC communication, the digital input (DI) module and the digital output (DO) module.

All data are set by communication. For details, see the

Module Type Controller SRX Communication Instruction Manual (IMS01N01-E).

6. WIRING

6.1 Wiring Cautions

 For thermocouple input, use the appropriate compensation

wire.

 For RTD input, use low resistance lead wire with no

difference in resistance between the three lead wires.

 To avoid noise induction, keep input signal wire away from

instrument power line, load lines and power lines of other electric equipment.
