Schneider Electric RXG22B7 RXG Relay 24 V AC

RXG22B7 RXG interface plug-in relay and its part number

RXG22B7 is an RXG interface plug-in relay from the Schneider Electric Harmony Electromechanical Relays range. Its datasheet lists 2 C/O contacts, an AC coil rated 24 V AC, 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 (2 C/O), the second distinguishes versions without and with LED, and the suffix B7 identifies the coil, here 24 V AC. 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 RXG22B7 in Oman and the GCC as an independent supplier in Muscat. The datasheet we hold is dated 8 Nov 2026.

Family comparison and RFQ details

For a quotation on RXG22B7 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 RXG22B7

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 RXG22B7 but differ as shown:

• Against RXG21BD: coil 24 V AC against 24 V DC on RXG21BD; an LED against no LED on RXG21BD; drop-out ≥ 0.3 Uc AC against ≥ 0.1 Uc DC on RXG21BD.
• Against RXG21JD: coil 24 V AC against 12 V DC on RXG21JD; an LED against no LED on RXG21JD; drop-out ≥ 0.3 Uc AC against ≥ 0.1 Uc DC on RXG21JD.
• Against RXG21P7: coil 24 V AC against 230 V AC on RXG21P7; an LED against no LED on RXG21P7.
• Against RXG22BD: coil 24 V AC against 24 V DC on RXG22BD; drop-out ≥ 0.3 Uc AC against ≥ 0.1 Uc DC on RXG22BD.

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

Installation, commissioning and maintenance

Fit the relay to its socket until it seats and, where a retaining feature is provided, secure it before energising. Do not hot-swap relays that are carrying load. For RXG22B7 the datasheet states -40–70 °C for operation and IP rating IP40, so plan cabinet ventilation accordingly.

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 RXG22B7 in Oman and the GCC

Relays of this class are used as interposing and interface devices between controllers and field loads in power generation, water treatment and desalination, oil and gas skids, and building automation across Oman. Humidity, dust and high cabinet temperature are the main environmental factors; the datasheet lists pollution degree 2 and IP rating IP40.

RXG22B7 suits panels that need 2 C/O switching with a status LED fitted and a lockable test button, and where the supply is 24 V AC.

Contact ratings and switching limits

Contact data for RXG22B7: maximum switching capacity 1250 VA, minimum switching capacity 50 mW at 10 mA, 5 V DC; contact material Silver alloy (AgSnO2In2O3).

Rated operational current entries:

• 5 A at 30 V (DC) conforming to UL
• 5 A at 30 V (DC) conforming to IEC
• 5 A at 250 V (AC) conforming to UL
• 5 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.

Coil circuit and supply window of RXG22B7

The coil of RXG22B7 is rated 24 V AC. The datasheet gives an average coil resistance of 260 Ohm at 23 °C ± 10 %. The relay releases when the control voltage falls to ≥ 0.3 Uc AC, 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 AC coil normally comes from a control transformer; confirm the transformer rating covers the coil load of every relay on it and that the secondary is fused.

Selection and ordering checklist for RXG22B7

Before ordering RXG22B7 confirm:

• Control voltage: 24 V AC; 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 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.
