Product Overview
The Omron G2R-2-SND DC24V is the LED-indicator + coil-suppression diode variant of Omron's G2R-series 8-pin DPDT (2-pole changeover, also called 2 form C) plug-in power relay. 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.
The relay has a single 24 VDC coil, two sets of changeover contacts (each contact: 1 NO + 1 NC with a common terminal = DPDT = 2-pole), and a continuous carry current of 5 A per pole. The 'S' suffix identifies the slim 8-pin form (P2RF-08-E socket) with 15.5 mm mounting pitch — half the width of the G2R standard series without S (which uses the 5-pin or 8-pin P2RF-08 / P2RF-08-E socket, also slim).
Pick the P2RFZ-08-E for retrofit into existing panels with screw terminals, or for CE/UL tight-torque verification.
Key Features
- Single 24 VDC coil, 21.8 mA at 24 VDC
- 5 A continuous carry current per pole at 250 VAC / 30 VDC
- G2R-series DPDT 8-pin plug-in relay
- Mechanical life 10 million operations min
- SKU: G2R-2-SND DC24V
- Series: G2R-S (slim 8-pin plug-in industrial relay)
- Voltage: 24 VDC
Best-Fit Applications
- Alarm output isolation for a chemical-mixer panel — CP2E transistor output controls G2R-2-SND DC24V coil, contacts switch a 24 VDC.
- Interface between a CP1L transistor output and a 3-phase motor contactor — CP1L transistor output drives G2R-2-SND DC24V coil, G2R.
- Logic-level to high-current relay bank — 8 × G2R-2-SND DC24V relays on P2RF-08-E sockets with P2RVC-P commoning bridge, providing 16.
Buying Checklist
- Pick G2R-2-SN AC100/110V for 100/110 VAC coil
- Pick G2R-1-SN DC24V-H for 10 A high-current variant
- Pick G2R-2-SND DC12V for a 12 VDC coil variant

FAQ for G2R-2-SND DC24V
Does the G2R-2-SND DC24V have the coil-suppression diode inside?
Yes — the 'D' in the suffix 'SND' stands for Diode. The relay has a coil-suppression diode (a bidirectional Zener / TVS combination, clamped at approximately 27 V) reverse-biased across the coil terminals, designed to absorb the back-EMF that occurs when the coil de-energizes.
What's the difference between P2RF-08-E and P2RFZ-08-E sockets?
Both are 8-pin sockets for the G2R-2-SN family. The P2RFZ-08-E is the legacy M3-screw-terminal socket — wires are clamped by tightening 0.4 N·m torque screws; requires periodic retightening in high-vibration environments and is the recommended socket for CE/UL applications where torque verification is part of the panel commissioning.
Can the G2R-2-SND DC24V switch 230 VAC motor contactor coils?
Yes — this is one of the most common applications for the G2R-2-SN family. The 5 A contact rating covers 230 VAC at any typical motor contactor coil current (typically 10-50 VA, i.e., 50-200 mA coil current at 230 VAC, well within 5 A).
What does the mechanical flag indicator do?
The mechanical flag indicator (a white-and-black flip-bar visible through the clear acrylic case on the front face of the relay) shows the contact state mechanically — even with the panel powered off. When the coil is energized, the flag moves to the 'operated' position; when the coil is de-energized, it returns to the 'released' position.
