Omron G2R-1-SN SPDT 10 A Relay with LED Indicator

G2R-1-SN: single-pole 10 A relay with coil LED

The Omron G2R-1-SN is the LED-indicator version of the single-pole G2R-S relay. Alongside the mechanical flag it carries a lamp that lights when the coil is energised, and on AC coil versions the datasheet describes a coil-disconnection self-diagnostic function. Seven Star LLC supplies the G2R-1-SN in Oman and the GCC as an independent supplier in Muscat. The sections that follow explain what the N adds and what to check when ordering.

• G2R is the slim power relay series.
• 1 means one pole, SPDT, 10 A.
• S means plug-in terminals.
• N means a LED indicator.
• The coil voltage and (S) are added at order, for example G2R-1-SN 24 VDC (S).

The LED is the practical difference: a technician can see the coil status from the front of a crowded panel without opening a meter.

G2R-1-SN technical specifications

Specifications are from the Omron datasheet. Check the LED coil data, since the added indicator slightly affects coil current.

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

The relay body, contact and ratings are the same as the plain G2R-1-S. The addition is a LED circuit in series with or across the coil that indicates energisation. On DC relays the LED is a convenience; on AC relays the datasheet describes the LED type as having a coil-disconnection self-diagnostic function.

That function is helpful when a coil winding opens: the lamp signals the condition. For full details of how the diagnostic behaves, consult the datasheet, as it depends on AC coil construction.

Coil data for G2R-1-SN

AC coils are 24, 48, 110, 120, 230 and 240 V and DC coils are 6, 12, 24 and 48 V.

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-SN

The G2R-1-SN uses the 5-pin sockets P2RF-05-PU, P2RF-05, P2RF-05-E, P2RFZ-05-E and the back-mount types. G2R-1-SNI adds a lockable test button to the same footprint, and G2R-1-SND adds a diode for DC coil suppression.

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-SN

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

• Confirm that LED indication is wanted in the panel.
• Choose AC or DC coil and voltage.
• Check load against 10 A at 250 VAC / 30 VDC.
• Decide whether a test button (SNI) or diode (SND) would help.
• Select socket type.
• Verify that the LED does not affect your coil driver, particularly with solid-state outputs.

Installation, commissioning and maintenance of G2R-1-SN

Install in a 5-pin socket and check coil terminals. The LED will light when the coil is energised.

• Check coil voltage marking before energising.
• On AC coil versions, understand how the LED self-diagnostic behaves before relying on it.
• Do not use the lever or test features on versions without them.
• Keep spares per coil voltage.
• Inspect sockets for heating marks annually.

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

LED-indicator relays are favoured where operators and technicians frequently check relay status: PLC output interface panels, HVAC and pump controls, and generator auxiliary cabinets. In Oman and the GCC the G2R-1-SN fits service-friendly designs where first-line maintenance staff diagnose faults visually.

LED indicators are particularly useful in dim marshalling rooms and in panels behind doors where measuring is inconvenient.
