Omron G2RV-ST500-AP 24VAC/DC Slimline Input Relay Guide

The Omron G2RV-ST500-AP 24VAC/DC slimline input relay is a versatile microload interface relay for automation panels that use either 24 VAC or 24 VDC control voltage. It is especially useful when a compact relay footprint and dependable low-current signal switching are required.

Technical Profile

Omron’s G2RV-ST family uses a slim relay with an integrated low-profile socket, Push-In Plus terminal structure, DIN rail mounting, LED indication, mechanical indication, and transparent housing. The AP version is the microload type and uses Ag alloy contacts with Au plating. :contentReference[oaicite:12]{index=12}

For the 24 VAC/VDC coil rating, Omron specifies rated current of 13.7 mA at 50 Hz, 14.9 mA at 60 Hz, and 12.6 mA DC. Approximate power consumption is 0.4 VA on AC and 300 mW on DC. The maximum allowable voltage is 110%. :contentReference[oaicite:13]{index=13}

The AP microload contact rating is 50 mA at 30 VAC and 50 mA at 36 VDC for resistive loads. Omron also lists SPDT contact configuration, 50 mA rated carry current, and a failure rate reference value of 1 mA at 100 mVDC. :contentReference[oaicite:14]{index=14}

Typical Uses

This relay is commonly used in PLC input circuits, sensor interface panels, process control systems, machine control cabinets, signal isolation circuits, and low-current alarm or indication lines. Its dual AC/DC compatibility can simplify spare part planning where 24 V control standards vary between machines.
