Omron G2R-1-S SPDT 10 A Slim Plug-In Power Relay

G2R-1-S: slim single-pole 10 A plug-in relay

The Omron G2R-1-S is a slim general-purpose plug-in power relay with one changeover contact rated 10 A. It carries a built-in mechanical operation indicator and a nameplate, and fits 5-pin sockets, including the Push-In Plus P2RF-05-PU. Seven Star LLC supplies the G2R-1-S in Oman and the GCC as an independent supplier in Muscat. This page decodes the part number and lists the points to confirm when ordering.

• G2R is the slim power relay series.
• 1 means one pole (SPDT).
• S means plug-in terminals.
• No further letter means the general-purpose version without LED or diode.
• The ordering code adds the rated coil voltage and (S), for example G2R-1-S 12 VDC (S).

The 1-pole body is only about 20 g, yet it switches 10 A, which is why it is a frequent first choice for load switching in compact control cabinets.

G2R-1-S technical specifications

Values are from the Omron G2R-@-S(S) datasheet. Gold-plated contact versions are available on request from the manufacturer for low-level signals; they are not part of this standard model.

How G2R-1-S switches and what the options add

A coil moves an armature to transfer a single changeover contact between its normally closed and normally open positions. With only one pole, the contact gap and spacing are larger than on the 2-pole body, and that is the reason the dielectric strength between coil and contacts reaches 5,000 VAC and the contact rating reaches 10 A.

The G2R-1-S has no LED or diode, so it is the plainest version. The mechanical flag shows contact position, helpful when diagnosing without a meter. The coil can be AC or DC, and AC coil versions run slightly higher power consumption than DC.

Coil data for G2R-1-S

Standard AC coils are 24, 48, 110, 120, 230 and 240 V; DC coils are 6, 12, 24 and 48 V. Data from the datasheet:

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-1-S

The G2R-1-S plugs into 5-pin sockets. The Push-In Plus P2RF-05-PU cuts wiring time by about 60% according to Omron measurements, while screw sockets suit conventional panels. The 2-pole equivalent is G2R-2-S on an 8-pin socket. Options with LED (G2R-1-SN), test button (G2R-1-SNI) and diode (G2R-1-SD) share the same 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-1-S

Confirm the following before requesting a quotation for G2R-1-S.

• Decide whether one 10 A pole is enough; if two circuits are needed use G2R-2-S at 5 A per pole.
• Choose AC or DC coil and the voltage.
• Check load type: 10 A resistive and 7.5 A inductive at 250 VAC.
• Decide if LED, diode or test button versions are better for your panel.
• Choose a socket type: Push-In Plus, screw or PCB.
• State if gold-plated contacts are needed for dry-circuit signals.

Installation, commissioning and maintenance of G2R-1-S

Plug the G2R-1-S into its socket and ensure the retaining clip or the socket frame holds it. Observe correct coil terminals and confirm the coil voltage marking.

• Use the mechanical indicator to confirm operation during testing.
• Keep inductive loads suppressed at the load.
• Keep spacing between adjacent relays at full load to limit heat.
• Do not exceed 110% of rated coil voltage.
• Stock spares by coil voltage, as AC and DC coil relays look alike.

Typical G2R-1-S applications in Oman and the GCC

The G2R-1-S is a workhorse for switching contactor coils, solenoid valves, heaters and lamps from low-power control outputs. In Oman and the GCC it appears in HVAC control panels, pump starters, package unit controls and relay interface modules for PLC outputs.

Where panel temperatures are high the relay is rated for operation up to 70°C, but contact loading should be reduced when running at the limit. Dust ingress should be managed by sealed enclosures.

A few practical habits extend relay life in service. Load the contact below its resistive rating whenever the circuit is inductive, keep the coil voltage close to nominal rather than relying on the wide operating window, and avoid mounting relays directly above heat-producing components. When a panel is modified, record the coil voltage and socket type on the drawing, because replacement relays that look identical but carry a different coil rating are a common source of burnt coils during urgent repairs. Where relays are replaced on a schedule rather than on failure, the date of installation can be written on the nameplate area that the relay body provides, which makes it simple to see at a glance which units have served longest. Ordering a modest overstock of the common coil voltages at the time of the first purchase usually costs less than later urgent freight.
