Product Overview
The 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. 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.
How the ST500 differs from siblings
Within the G2RV-ST family the 5xx suffix indicates no latching lever (test switch) and the 7xx suffix indicates with latching lever — same SPDT contact, same 6 A rating, same Push-In Plus socket. The ST500 is the right pick for cost-sensitive interfaces where manual actuation is not needed (most production panels); the ST700 is preferred in test stands where engineers want to force the relay closed with the lever without powering the coil. If you need a solid-state equivalent (silent switching, longer life, no moving parts) order the G3RV-ST500 DC24 instead.
Wiring and accessories
The Push-In Plus socket is shipped pre-assembled with the relay and accepts solid wire, stranded wire with ferrule, or twisted pair — strip length 8 mm, 0.5 to 2.5 mm² conductor cross-section. Coil terminals are A1 (+) and A2 (−); contact terminals are 11 (common), 12 (NC), 14 (NO). When you line up multiple G2RV-ST500 relays side by side, use the optional P2RVC-8ST-I-□□□ input bridge to common A1 / A2 across 8 relays with a single wire from the PLC output — dramatically reducing the number of jumper wires in a 16-channel output bank.
Use cases in a typical control cabinet
The G2RV-ST500 DC24 is most often seen between a CJ2 or NX PLC output and a 24 VDC valve solenoid, indicator lamp, or low-power contactor coil. Because the socket accepts the relay as a plug-in module, a failed relay can be swapped in seconds without disturbing the wiring — ideal for production lines where downtime matters. 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.

Buying Checklist
- Choose G2RV-ST500 DC24 when you do not need a manual test lever; choose ST700 DC24 when you do
- Choose G3RV-ST500 DC24 instead if you need a silent solid-state output with no moving contacts
- Order P2RVC-8ST-I-□□□ input bridges and P2RVC-8ST-O-□□□ output bridges when banking multiple relays
- Order PYDN-6.2ST replacement sockets if the relay itself is fine but the socket has been damaged
- Match coil voltage to your PLC output rating — 24 VDC for CJ2/NX transistor outputs
- For micro-load switching, order the -AP Au-plated variant

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.
