MU-653

The MU-653 relay output module is designed for "on/off" control of technological systems.

The module is equipped with six relays divided into two groups of three. Both groups are isolated from other circuits of module (power supply and RS-485 interface) and from each other with high insulation strength (safety isolation), signals within each group are isolated with lower insulation strength. All relay outputs are protected against impulse overvoltage by 250VRMS varistors.

The module is equipped (in addition to two standard LEDs for power supply and RS-485 line activity) with six LED“s indicating the status of the relays.
