Product Overview
The Omron G2R-2-SND DC24(S) is a 24 VDC DPDT plug-in relay from the G2R family, built for interposing between a PLC output and a field load. The 2 means DPDT (2 Form C) - two complete sets of NO+NC contacts, each rated 5 A at 250 VAC or 30 VDC resistive. The S marks the standard housing, N adds the LED operation indicator, and D adds a coil-surge absorption diode that kills back-EMF when the coil de-energises. Pick this relay when you need a serviceable 24 VDC DPDT relay to switch two independent loads from one PLC output, with on-board status feedback and quiet coil switching.
Why DPDT in a single relay
Most interposing duties use SPDT to switch one load from one PLC output. The DPDT gives two independent NO/NC pairs in the same 29 mm body - you wire one pair to a contactor coil and the second to a status indicator or interlock. In fail-safe circuits, wiring both contacts into the same dual-channel safety logic gives a mechanically linked pair that opens together, satisfying the redundancy requirement for higher safety categories with one relay rather than two.
Decoding the G2R-2-SND DC24(S) code
G2R is the family; 2 marks the DPDT 5 A version, S the standard housing, N the LED, D the coil-surge diode. The DC24(S) suffix is the 24 VDC coil. Pick G2R-2-SN for a plain DPDT without LED or diode. Pick LY2N-J DC24 for the legacy LY-series pinout at the same 5 A DPDT rating.
Before ordering
Confirm the coil is 24 VDC - the same G2R-2-SND body is available in DC12V, DC48V, DC100V, and several AC coils. Order the P2RF-08-E octal socket for screw-terminal DIN-rail mounting, or P2R-08P for PCB mount. Wire the coil terminals (A1, A2) to the 24 VDC source, the COMs to the circuits being switched, and NO/NC to the loads. Verify each pole stays within 5 A at rated voltage, and derate to 2 A on inductive loads.

Best-Fit Applications
- Interposing a 24 VDC PLC output to switch a 100-240 VAC contactor coil in a cabinet.
- Switching two independent field loads from one PLC output (e.g. indicator light + solenoid valve).
- Signal isolation and voltage-level translation between mismatched control sections.
- Fail-safe relay logic that sits alongside a PLC for legacy panels needing simple discrete wiring.
- Serviceable relay replacement where the original Omron LY2N or G2R-2 in an old panel has failed.
Buying Checklist
- Confirm the coil voltage is 24 VDC - the same G2R-2-SND body is available in DC12V, DC48V, DC100V, and several AC coils.
- Choose G2R-2-SN for the same DPDT relay without the LED or diode when you do not need on-board status.
- Choose the P2RF-08-E octal socket for screw-terminal DIN-rail mounting, or the P2R-08P for PCB through-hole.
- Verify each pole stays within 5 A at rated voltage - derate to 2 A on inductive loads or use a contactor.
- Allow for the 10-15 ms release time in high-speed counting - the solid-state G3NA-210B-UTU is sub-millisecond.

FAQ for G2R-2-SND DC24(S)
What is the difference between G2R-2-SND DC24(S) and G2R-2-SN?
Both are DPDT 5 A plug-in relays in the same G2R housing with the same octal 8-pin footprint. The SND adds the LED operation indicator (N) AND a coil-surge absorption diode (D). The plain SN has neither. Pick the SND on new builds - the LED confirms the coil is energised, and the diode protects the driving PLC output from coil back-EMF.
What socket fits the G2R-2-SND DC24(S)?
Use the P2RF-08-E for finger-safe screw-terminal DIN-rail or panel mounting, or the P2R-08P for through-hole PCB mounting. Both are 8-pin octal sockets sized for the G2R-2 DPDT pin-out. The P2RF-08-E accepts ring or fork lugs and ships with a hold-down clip.
Does the diode on the G2R-2-SND slow the relay release?
Yes - the coil diode adds 5 to 10 ms to the release time versus a non-diode relay. That is fine for interposing, contactor driving, and most logic interlock duty. If the application is high-speed counting or sequencing at sub-50 ms cycle, choose the G2R-2-SN without the diode, or step up to the G2RV-ST500 solid-state slim relay for sub-millisecond switching.
