Schneider Electric RXG12BD RXG Relay 24 V DC

RXG12BD RXG interface plug-in relay and its part number

RXG12BD is an RXG interface plug-in relay from the Schneider Electric Harmony Electromechanical Relays range. Its datasheet lists 1 C/O contacts, a DC coil rated 24 V DC, and a status LED fitted. 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 (1 C/O), the second distinguishes versions without and with LED, and the suffix BD identifies the coil, here 24 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 RXG12BD in Oman and the GCC as an independent supplier in Muscat. The datasheet we hold is dated 8 Nov 2026.

Contact ratings and switching limits

Contact data for RXG12BD: maximum switching capacity 2500 VA, minimum switching capacity 500 mW at 100 mA, 5 V DC; contact material Silver alloy (AgSnO2In2O3).

Rated operational current entries:

• 10 A at 30 V (DC) conforming to UL
• 10 A at 30 V (DC) conforming to IEC
• 10 A at 250 V (AC) conforming to UL
• 10 A at 250 V (AC) conforming to IEC

Durability: 100000 cycles for NO resistive load at 55 °C and 100000 cycles for NC resistive load at 55 °C. Derate for inductive or DC loads and follow the curves in the datasheet.

Installation, commissioning and maintenance

Start by checking the socket wiring against the relay pin diagram, then plug the relay in and energise. RXG12BD 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.

Typical use of RXG12BD 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. Heat inside sun-exposed cabinets and salt-laden coastal air are the main points to design for; the datasheet lists pollution degree 2 and IP rating IP40.

RXG12BD suits panels that need 1 C/O switching with a status LED fitted and a lockable test button, and where the supply is 24 V DC.

Selection and ordering checklist for RXG12BD

Before ordering RXG12BD confirm:

• Control voltage: 24 V DC; AC and DC versions are not interchangeable.
• Contact load: check the load against 2500 VA and the current table above.
• Indicator needs: this version is with 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.

RXG12BD technical specifications

Family comparison and RFQ details

For a quotation on RXG12BD 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.

Coil circuit and supply window of RXG12BD

The coil of RXG12BD is rated 24 V DC. The datasheet gives an average coil resistance of 1100 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. The LED also shows coil energisation.

A 24 V DC coil is the usual match for PLC digital outputs and regulated control rails, so check that the output card can source the coil current and that the rail is not shared with noisy inductive loads.

Sockets and related parts for RXG12BD

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 RXG12BD but differ as shown:

• Against RXG21BD: an LED against no LED on RXG21BD; 1 C/O contacts against 2 C/O on RXG21BD; 10 A thermal current against 5 A on RXG21BD.
• Against RXG21JD: coil 24 V DC against 12 V DC on RXG21JD; an LED against no LED on RXG21JD; 1 C/O contacts against 2 C/O on RXG21JD.
• Against RXG21P7: coil 24 V DC against 230 V AC on RXG21P7; an LED against no LED on RXG21P7; 1 C/O contacts against 2 C/O on RXG21P7.
• Against RXG22B7: coil 24 V DC against 24 V AC on RXG22B7; 1 C/O contacts against 2 C/O on RXG22B7; 10 A thermal current against 5 A on RXG22B7.

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