[Design Precautions]

WARNING

●A safety relay module turns OFF all outputs by safety input or a failure of external power supply. Create an external circuit to securely stop the power of hazard by turning OFF the outputs. Incorrect configuration may result in an accident.

●When overcurrent due to such as load short-circuit or load current exceeding the rating flows for a long time, it may cause smoke or fire. To prevent this, create external safety circuit such as a fuse.

●Create short-circuit current protection for a safety relay and a protection circuit such as a fuse and breaker, outside a safety relay module.

●To inhibit a restart without manual operation after safety function of the safety relay module was performed and outputs were turned OFF, create reset start-up circuit using such as a reset switch outside the safety relay module.

●The safety relay module may consume excessive current due to a failure. If this occurs, the DC power supply connected to the safety power supply part (+24V (SAFETY) and 24G (SAFETY) terminals) of the module detects an overcurrent and may shut off the output. To the DC power supply connected to the safety relay module, connect only the equipment and the devices that will not affect the system even if they are simultaneously stopped due to power-off.

●Use an extension module whose input type is the same as that of the main module. The modules of different input types (input P and N types) cannot be connected.

1.3 Features	1 - 3

1 OVERVIEW

(5)Small-scale safety control

The safety relay module is suited for small-scale safety control whose number of I/O points is around 10.

(a)Programming is unnecessary.

Safety circuits can be easily created only by wiring, without programming and settings.

Since an inspection on programming by safety certification organization is unnecessary, the man-hour taken for obtaining the safety approval can be omitted.

(b)Extension of safety circuit with extension module

By connecting extension safety relay modules, maximum 4 points of safety input and maximum 4 points of safety output can be controlled.

(c)Safety control can be performed by itself.

Since a communication circuit for Q series programmable controller and CC-Link is separated from a circuit for achieving the safety function, the safety relay module can perform safety control by itself, independent of a failure of the Q series programmable controller or CC-Link communication status.

(6)Fail safe

Fail safe can be achieved by inhibiting the safety relay module from starting when an error occurs in safety input, start-up input, and/or internal circuit of the safety relay module.

(7)Improvement of efficiency in wiring work

Using spring clamp terminal block allows to skip screw tightening work and to reduce wiring work significantly.

(8)Connector insertion check

Using terminal block cover for connector insertion check prevents poor connection. If the terminal block is not inserted securely, the terminal block cover does not close.
