Product Overview
The Omron G2RV-ST500 DC24 is Omron's narrowest plug-in I/O relay: a complete relay-and-socket assembly at only 6.2 mm wide, giving roughly 16 channels per 100 mm of DIN rail. manufactured by Omron Corporation. Hengyixin Automation stocks this relay in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
It carries one SPDT contact rated 6 A at 250 VAC or 6 A at 30 VDC (resistive load), with an Au-plated contact variant available for low-level signals down to 1 mA at 100 mVDC. The 24 VDC coil draws roughly 11 mA and consumes about 180 mW, matching the standard 24 V control rail in most PLC cabinets, and the built-in LED indicator wired across the coil confirms energise / drop-out at a glance.
For applications that need isolation between PLC and field, the relay provides 4 kV coil-to-contact dielectric withstand and 5 kV surge resistance, well above IEC 61810-1.
Key Features
- 24 VDC coil, ~11 mA pickup, ~180 mW holding
- Complete relay + socket assembly at only 6.2 mm wide for high-density panels
- SPDT contact rated 6 A at 250 VAC / 6 A at 30 VDC
- Push-In Plus terminals accept 0.5–2.5 mm² wire without a screwdriver
- SKU: G2RV-ST500 DC24
- Series: G2RV-ST
- Voltage: 24 VDC
Best-Fit Applications
- Status-signal interface between a 24 VDC control system and a 230 VAC indicator lamp
- Interposing relay between PLC DO and 24 VDC solenoid valve on a packaging line
- Replacement part for a high-cycle machine that has worn through its first generation of relays
Buying Checklist
- Choose G3RV-ST500 DC24 instead if you need a silent solid-state output with no moving contacts
- Choose G2RV-ST500 DC24 when you do not need a manual test lever; choose ST700 DC24 when you do
- Match coil voltage to your PLC output rating — 24 VDC for CJ2/NX transistor outputs

FAQ for G2RV-ST500 DC24
What is the difference between G2RV-ST500 and G2RV-ST700?
Both are 6.2 mm slim SPDT relays rated 6 A with Push-In Plus terminals and the same coil voltages. The ST700 has a latching lever (test switch) on top that holds the relay closed manually without energising the coil — useful for test stands and commissioning. The ST500 omits the lever for a slightly lower price, which is the right choice for production panels that never need manual actuation. Coil voltage suffixes are identical (DC24, AC100, AC200, etc.).
Can I replace just the relay, or do I have to replace the whole socket?
Just the relay. The socket (Omron part PYDN-6.2ST-□□□) is a separate piece, and the relay module plugs into it. Pull the failed relay straight out by hand, push a fresh G2RV-ST500 module in. The wiring on the socket terminals does not move. Keep a few spare relay modules in the spares cabinet for fast swap on a service call.
Is the G2RV-ST500 DC24 a solid-state or electromechanical relay?
Electromechanical (mechanical flag visible through the transparent housing, audible click on operate). If you need silent switching, no moving contacts, or very high cycle life, look at the G3RV-ST500 DC24 — it is the solid-state equivalent in the same 6.2 mm housing, but it has no SPDT option (SPST-NO only) and uses a triac or transistor output.
What is the maximum switching frequency of the G2RV-ST500 DC24?
Mechanical operations are rated at 5 million minimum with no load. At full 6 A resistive load the electrical life is 100,000 operations minimum. For on-off cycling faster than about 3 Hz (180 cycles/minute) the relay life drops noticeably because of contact wear; for high-frequency switching use a solid-state relay (G3RV) instead. For typical interposing-relay duty (PLC output to solenoid, indicator, or contactor coil), the cycle rate is well within spec.
