G2R-2-SN DC24(S)

Product information

Product Overview

A 2-pole plug-in general-purpose relay with a 24 VDC coil and an LED indicator, supplied with Omron’s mechanical operation indicator and nameplate. Omron’s catalogue number for this coil voltage and configuration is G2R-2-SN-24VDC-S.

This page is written for buyers and maintenance engineers sourcing G2R-2-SN DC24(S) as a new part or a replacement. Every specification below is taken from Omron’s own published data for this model; no third-party or estimated figures are used, and where Omron publishes two different figures or two variants for the same parameter, both are shown.

Omron catalogue designation: G2R-[]-S (S) general-purpose relay, plug-in. Official catalogue code for this model: G2R-2-SN-24VDC-S.

Why Buyers Specify This Model

5 A at 250 VAC on a plug-in body

The 2-pole G2R carries 5 A resistive at 250 VAC or 30 VDC, with a rated carry current of 5 A and a maximum switching power of 1,250 VA / 150 W. That is a real load capability in a plug-in footprint — and because it is plug-in, a failed relay is a swap, not a rewire.

The LED indicator is worth having on service

The “N” in the model number is the LED indicator. On a panel with dozens of identical relays, being able to see which coil is energised without a meter is the difference between a short diagnosis and a long one. It is a small uplift on the part cost and a large reduction in fault-finding time.

AC and DC ratings are not the same relay with a different coil

Omron publishes separate contact ratings for resistive loads at cosφ = 1 and inductive loads at cosφ = 0.4 with L/R = 7 ms, and the inductive figures are roughly half the resistive ones. Relay coils, solenoid valves and motor starters are inductive. Quoting the 5 A resistive figure against a solenoid is the classic way to shorten contact life.

Must-operate at 70% gives supply headroom

The coil will operate from 70% of rated voltage and release below 15%, with a 110% maximum. That tolerance band matters on a 24 V rail that sags under load — a relay that needs 90% would chatter in the same panel.

Omron’s catalogue writes this family as G2R-□-S (S) — the box is the pole count and the suffixed letters identify the indicator and diode options. The DC 24 V coil version is listed as G2R-2-SN-24VDC-S. The corresponding AC 24 V coil version is a different part number from the same table.

Lifecycle and availability

The G2R-[]-S family is documented in Omron’s current general-purpose relay datasheet, which carries the complete coil ratings, contact ratings and characteristics reproduced here. Nothing in the official data carries a discontinuation notice for this model.

General-purpose relays are consumable items, which is why the plug-in format matters: the coil and contacts are rated for a finite number of operations, and the practical question for a maintenance team is how fast a replacement can be fitted. Send the coil voltage and the quantity — and if you are replacing one, the label details — and we will confirm the exact number together with the correct socket.

Availability, condition of supply and lead time are quoted per enquiry because they depend on quantity and on where the goods are held. We do not publish stock or lead time as fixed figures on this page. Tell us the quantity and the date you need it and we will answer with a firm position rather than a promise.

Full technical detail — wiring diagrams, derating curves, installation requirements and the complete ordering tables — is in that document. If you need a specific figure we do not show here, ask and we will point you to the exact page rather than paraphrase it.

Ordering This Part

Send us the full catalogue number G2R-2-SN-24VDC-S (and the model number G2R-2-SN DC24(S) you are replacing), the quantity, your delivery address and the date you need the goods. If it is a replacement, attach a photograph of the existing unit’s nameplate — it removes any doubt about the revision, the output type or the supply voltage, which are the three things that most often cause a wrong part to be shipped.

We do not publish stock, condition or lead time as fixed figures here, because they change: they are quoted per enquiry against the quantity and date you actually need. If a machine is down, say so and give us the required window — that is the information that determines how we source it.

Frequently Asked Questions

What exactly is the official Omron part number?

G2R-2-SN-24VDC-S. The catalogue family is written G2R-□-S (S) where the box denotes pole count; “SN” denotes the LED-indicator version with two poles, and the “-24VDC-S” identifies the 24 VDC coil. The “DC24(S)” form you have listed resolves to this number — confirm it against your requirement before ordering.

What socket does it need?

The G2R-[]-S family is plug-in and Omron lists sockets, clips and marking plates separately for it. Tell us the mounting arrangement — DIN rail or panel, and whether the socket should be screw or PCB — and we will quote the relay with the matching socket and clip so the assembly is complete.

SN, SND or SNI — what do the letters mean?

Omron’s own model list separates them: SN is LED indicator, SND is LED indicator plus diode, and SNI is LED indicator with a test button. The diode version matters when the relay is driven by a transistor output; the test button matters for commissioning and fault-finding. Choose deliberately.

Can I switch 250 VAC with it?

Yes — 5 A resistive at 250 VAC per the official contact ratings, and the maximum switching voltage is 380 VAC. Check the load type as well as the voltage: inductive loads are rated lower.
