Why Choose the IMO PLME1 Relay Socket Plug-In Module?
The IMO PLME1 is a 6–24 V DC relay socket plug-in module designed to provide coil suppression and visual status indication in compatible IMO relay socket assemblies. Combining a diode, LED and resistor in one compact module, it provides a convenient accessory for industrial relay control circuits.
The integrated diode helps protect the relay coil circuit by suppressing the reverse voltage generated when a DC relay coil is de-energised, while the built-in LED provides visual indication when the coil is energised. The resistor forms part of the LED indication circuit, allowing these functions to be incorporated without separately wiring individual components.
The PLME1 operates across a 6–24 V DC range and is designed for compatible IMO relay sockets including the SRNE2-D/S, SRNE3-D, SRNE4-D/S, SRNE3-S/T and SRNE5-S/T families. Its plug-in format provides a simple way to add coil protection and indication to industrial relay installations.

Relay Coil Protection with Visual Status Indication
DC relay coils are inductive loads and can generate a reverse voltage when their supply is removed. A suppression diode provides a path for this stored electrical energy, helping limit the resulting voltage transient and reducing electrical stress on components controlling the relay coil.
The IMO PLME1 combines this suppression function with an LED indication circuit. When installed with the correct polarity in a compatible relay socket, the module provides both coil protection and a visible indication of coil voltage, making relay status easier to identify during operation, commissioning and fault finding.
