Schneider Electric RPM22BD RPM Relay 24 V DC

RPM22BD RPM power plug-in relay and its part number

RPM22BD is an RPM power plug-in relay from the Schneider Electric Harmony Electromechanical Relays range. Its datasheet lists 2 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: RPM22 = RPM series power relay with two changeover contacts; the suffix BD stands for 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 RPM22BD in Oman and the GCC as an independent supplier in Muscat. The datasheet we hold is dated 8 Nov 2026.

Sockets and related parts for RPM22BD

The matching sockets are RPZF2 for the two-pole RPM relay and RPZF4 for the four-pole one; the datasheet of the socket confirms RPM with 2 C/O contact for RPZF2.

The same series also includes the following parts, which share the basic body of RPM22BD but differ as shown:

• Against RPM22P7: coil 24 V DC against 230 V AC 50/60 Hz on RPM22P7; drop-out ≥ 0.1 Uc DC against ≥ 0.15 Uc AC on RPM22P7.

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

Coil circuit and supply window of RPM22BD

The coil of RPM22BD is rated 24 V DC with voltage limits of 19.2–26.4 V DC. The datasheet gives an average coil resistance of 640 Ohm at 20 °C ± 10 % and average consumption of 0.85 W. 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.

Operating time is 20 ms at nominal voltage and release time 20 ms at nominal voltage. An LED shows coil energisation, and the lockable test button allows manual operation checks.

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.

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 RPM22BD the datasheet states -40–55 °C for operation and IP rating IP40 conforming to IEC 60529, 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.

RPM22BD technical specifications

Typical use of RPM22BD 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. Heat inside sun-exposed cabinets and salt-laden coastal air are the main points to design for; the datasheet lists pollution degree 3 and IP rating IP40 conforming to IEC 60529.

RPM22BD 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 DC.

Selection and ordering checklist for RPM22BD

Before ordering RPM22BD confirm:

• Control voltage: 24 V DC (19.2–26.4 V DC); AC and DC versions are not interchangeable.
• Contact load: check the load against 3750 VA; 420 W and the current table above.
• Indicator needs: this version is with a status LED.
• Socket type and terminal style matching the relay pins.
• Quantity and whether a spare relay should be held for the plant.
