Murrelektronik 90002 EK 10/SM Relay I/O Board
The Murrelektronik 90002 EK 10/SM is an industrial relay and I/O circuit board for use in machine controls and automation systems. The plug-in board is equipped with ten electromechanical relays multiple red status indicators and a multipole card connector.
The board was removed from a machine that was operational before dismantling and is in good used condition.
Function and application
The relay board is used as an interface between a higher-level controller and the connected circuits of a machine. Its individual relay channels can switch electrical signals or loads while providing galvanic isolation from the control circuit.
The red indicators provide visual monitoring of various switching states. The board is installed in a compatible card rack or control unit through its multipole card connector.
The exact original application within the machine and the electrical pin assignment could not be determined.
