OMRON G9SR-EX031-T90-RC Safety Relay 24VDC 3NO Timer Expansion Unit

When a machine needs a safe way to start and stop, missing timing control can cause accidents or costly downtime. This problem matters because unsafe stops can damage equipment and put workers at risk. The OMRON G9SR-EX031-T90-RC Safety Relay 24VDC 3NO Timer Expansion Unit adds reliable timing and safe switching, giving you a clear solution that protects people and keeps production running.

OMRON G9SR-EX031-T90-RC Safety Relay 24VDC 3NO Timer Expansion Unit with OMRON

This unit is a compact expansion module that works with an OMRON advanced safety relay. It adds three safety contacts and a built-in timer, so you can set safe ON-delay and OFF-delay periods. If you have a line that must wait before a motor starts, or you need a guaranteed stop time, this relay gives you that control. It solves the common issue of missing safe timing in automated equipment.

Usages

The expansion unit fits into any OMRON safety system that needs extra timing. Use it on conveyor belts where a short pause prevents product jams. Install it on robotic cells to give a safe gap before a robot arm moves. It also works well in packaging machines that require a delay before sealing. The module can be placed up to one meter from the main unit, making wiring simple.
