Omron G2R-2-SN DPDT 5 A Relay with LED Indicator

G2R-2-SN: two-pole 5 A relay with coil LED

The Omron G2R-2-SN combines the two-pole slim G2R body with a coil LED. It provides two 5 A changeover contacts, a mechanical flag and a lamp showing coil status, making it a convenient relay for panel interfaces that are checked by eye. Seven Star LLC supplies the G2R-2-SN in Oman and the GCC as an independent supplier in Muscat. The details below cover the decoding and the ordering checklist.

• G2R is the slim power relay series.
• 2 means two poles (DPDT), 5 A each.
• S means plug-in terminals.
• N means a LED indicator.
• Coil voltage and (S) are added at order, for example G2R-2-SN 24 VDC (S).

Choosing the G2R-2-SN over the plain G2R-2-S costs no extra panel space but adds visible status, which pays back in fault-finding time.

G2R-2-SN technical specifications

Values come from the Omron G2R-@-S(S) datasheet. As with other LED relays, the lamp circuit adds a small amount to the coil current.

How G2R-2-SN switches and what the options add

The relay operates two contacts from one coil. The LED across the coil lights when energised, and the mechanical flag moves with the contacts. A fault can then be sorted quickly: LED on and flag not moved suggests a mechanical problem, while LED off with control signal present suggests a coil or wiring fault.

On AC coil versions the datasheet notes a coil-disconnection self-diagnostic function in the LED type. The contacts are rated 5 A at 250 VAC or 30 VDC resistive, with 380 VAC as maximum switching voltage.

Coil data for G2R-2-SN

The same coil options as the other G2R-S relays are available, shown below.

Must-operate voltage is 80% max. of rated for AC coils and 70% max. for DC coils; must-release voltage is 30% max. for AC and 15% min. for DC. Maximum voltage is 110% of rated. Power consumption is approx. 0.9 VA at 60 Hz for AC and approx. 0.53 W for DC.

Sockets and related parts for G2R-2-SN

The 8-pin sockets are P2RF-08-PU (Push-In Plus), P2RF-08, P2RF-08-E and P2RFZ-08-E (screw) and P2R-08P, P2R-087P and P2R-08A for back mounting. The siblings G2R-2-S (no LED), G2R-2-SND (LED and diode) and G2R-2-SNI (LED and test button) share the footprint.

Accessories listed with the series include short bars, label sheets (XW5Z-P4.0LB1 for Push-In Plus and XW5Z-P2.5LB1 for screw sockets), mounting tracks PFP-50N, PFP-100N and PFP-100N2, end plate PFP-M and spacer PFP-S. P2RF-@-E sockets are finger-safe and require forked, not round, crimp terminals.

Selection and ordering checklist for G2R-2-SN

Confirm the following before requesting a quotation for G2R-2-SN.

• Confirm LED indication and two poles are both needed.
• Select AC or DC coil and voltage.
• Check each pole against 5 A at 250 VAC.
• Decide whether a diode (SND) or test button (SNI) would add value.
• Choose an 8-pin socket type.
• Check coil driver compatibility with the LED.

Installation, commissioning and maintenance of G2R-2-SN

Seat the G2R-2-SN in its 8-pin socket and check coil terminals. Confirm the LED lights when the coil is energised.

• Check coil marking before energising.
• Compare the LED state with the flag position during commissioning.
• Add suppression for inductive loads.
• Space relays to limit heat.
• Keep spares per coil voltage.

Typical G2R-2-SN applications in Oman and the GCC

The G2R-2-SN suits interface relays for PLC outputs, two-circuit switching and status repeat duty. In Oman and the GCC it is commonly specified for pump-station panels, AHU and chiller control cabinets and packaged skids where technicians need quick diagnostics.

In sites with dusty air, relays should be kept in sealed cabinets; the LED then provides status without opening the panel door only if a window or door-mounted view is arranged.

When specifying LED relays, think about how the status will be read in practice. If the panel door hides the relay row, a LED has little value, whereas an open rack or a glass-fronted cabinet makes it very useful. In large installations some owners standardise on LED versions for every interface relay so that operators learn one visual language, and keep the plain versions only where space or cost forces the choice. Either approach works well if the choice is written into the project specification.
