Schneider Electric RXG21JD RXG Relay 12 V DC

RXG21JD RXG interface plug-in relay and its part number

RXG21JD is an RXG interface plug-in relay from the Schneider Electric Harmony Electromechanical Relays range. Its datasheet lists 2 C/O contacts, a DC coil rated 12 V DC, and no status LED. Mounting is plug-in, with flat faston-type pins.

Reading the code from the datasheets of this family: RXG = RXG series interface relay; the first digit after it gives the contact count (2 C/O), the second distinguishes versions without and with LED, and the suffix JD identifies the coil, here 12 V DC. This reading follows how the sibling datasheets line up and is not an ordering table, so verify the full code against the manufacturer catalogue when it matters.

Seven Star LLC supplies RXG21JD in Oman and the GCC as an independent supplier in Muscat. The datasheet we hold is dated 8 Nov 2026.

Typical use of RXG21JD in Oman and the GCC

In Oman and the GCC, relays like this commonly sit in motor control centres, pump and compressor skids, fire-and-gas panels, HVAC plant rooms and utility switchrooms, where they isolate PLC outputs from heavier circuits. Cabinet temperature, dust and condensation after air-conditioning shutdowns are the main points to watch; the datasheet lists pollution degree 2 and IP rating IP40.

RXG21JD suits panels that need 2 C/O switching with no status LED and a lockable test button, and where the supply is 12 V DC.

Contact ratings and switching limits

Contact data for RXG21JD: maximum switching capacity 1250 VA, minimum switching capacity 50 mW at 10 mA, 5 V DC; contact material Silver alloy (AgSnO2In2O3).

Selection and ordering checklist for RXG21JD

Before ordering RXG21JD confirm:

• Control voltage: 12 V DC; AC and DC versions are not interchangeable.
• Contact load: check the load against 1250 VA and the current table above.
• Indicator needs: this version is without a status LED, with a mechanical flag.
• Socket type and terminal style matching the relay pins.
• Quantity and whether a spare relay should be held for the plant.

Installation, commissioning and maintenance

Start by checking the socket wiring against the relay pin diagram, then plug the relay in and energise. RXG21JD is described with IP rating IP40, and its ambient limits are -40–70 °C for operation; keep it clear of heat sources such as power supplies and braking resistors in the same enclosure.

During commissioning, energise the coil at its nominal voltage, check contact transfer with a meter, and verify that the supply stays inside the voltage limits. In service, inspect for discoloured pins, replace relays that show contact wear, and keep a spare on the shelf for critical interlocks.

Coil circuit and supply window of RXG21JD

The coil of RXG21JD is rated 12 V DC. The datasheet gives an average coil resistance of 270 Ohm at 23 °C ± 10 %. The relay releases when the control voltage falls to ≥ 0.1 Uc DC, which is the figure to compare against any sagging control supply or leakage from a PLC output.

The datasheet shows operate and release times of 20 ms each, and a mechanical flag as local signalling, so contact position can be seen at the front even without an LED. This version has no LED, so the flag is the only local indication.

A 12 V DC coil points to battery-backed or low-voltage auxiliary circuits; verify the rail voltage under load, because the coil limits leave less room than a mains-fed supply.

Family comparison and RFQ details

For a quotation on RXG21JD please send the exact part number, quantity, coil voltage, delivery location in Oman or the GCC and any project reference. If your drawing lists a different coil voltage, say so and we will check the matching variant.

Sockets and related parts for RXG21JD

The datasheets we hold do not name a specific socket for this relay, so confirm the socket against Schneider Electric documentation or ask us to check before ordering.

The same series also includes the following parts, which share the basic body of RXG21JD but differ as shown:

• Against RXG21BD: coil 12 V DC against 24 V DC on RXG21BD.
• Against RXG21P7: coil 12 V DC against 230 V AC on RXG21P7; drop-out ≥ 0.1 Uc DC against ≥ 0.3 Uc AC on RXG21P7.
• Against RXG22B7: coil 12 V DC against 24 V AC on RXG22B7; no LED against an LED on RXG22B7; drop-out ≥ 0.1 Uc DC against ≥ 0.3 Uc AC on RXG22B7.
• Against RXG22BD: coil 12 V DC against 24 V DC on RXG22BD; no LED against an LED on RXG22BD.

Because the differences are in the coil or contact details, the complete part number must be confirmed before ordering.
