Omron Socket Power Relay, 110V dc Coil, 7A Switching Current, DPDT

Omron MM2XP Series Power Relay, 110V Coil Voltage, 7A Switching Current - MM2XP DC100/110

This power relay provides electromechanical switching for control and automation systems, converting a DC Coil input into a dual changeover contact output for use in industrial and electronic installations. It is intended for socket mounting and plug-in Terminal arrangements, offering a Compact footprint and a Coil designed for DC control voltages in moderate-temperature environments.

Features and Benefits:

• DPDT silver contacts reduce contact wear and enhance conductivity
  7A switching current supports moderate load circuits
  110V DC Coil consumes 2.1W for predictable drive requirements
  5750Ω Coil resistance enables straightforward Coil checking
  50mΩ contact resistance minimises voltage drop in switched circuits

Applications

• Suitable for control panels requiring dual changeover switching
  Ideal for industrial automation logic and relay interposing
  Used for signal routing in electronic testing rigs
  Can be used for auxiliary switching in mechanical systems

What Terminal and mounting arrangements are provided for Rapid installation?

The unit uses plug-in terminals and is designed for socket mounting to allow quick replacement and straightforward wiring during maintenance.

How does the relay behave across typical ambient temperatures?

It operates within a limited temperature range from -10°C up to 55°C, so it is suited to indoor and temperature-controlled industrial locations.

What materials and electrical loss characteristics affect contact performance?

The contacts are silver-based, offering low contact resistance measured at about 50mΩ which helps reduce contact heating and energy loss during switching.

How can technicians verify Coil integrity without specialised equipment?

Coil resistance is approximately 5750Ω
a Basic ohmmeter can confirm continuity and approximate resistance to identify Coil faults.

What Coil drive specifications should be matched by control circuitry?

The Coil requires a 110V DC supply and draws about 2.1W, so drive circuits must deliver that voltage and current for reliable actuation.
