Relay Module Boards (LMP)   have been designed in automatics engineering systems as coupling elements between electronic control circuits (for example PLC controllers) with executive devices.

• Modular structure - amount of relays is multiplicity of number 4 (e.g. 4, 8, 12 and 16)
• Common pole, independent, alternating current, direct current versions
• Each relay have one single-pole double-throw (SPDT) contacts
• LED diode indicates switched-on state of the relay
• Overvoltage protection of input/output circuits
