MU-623, MU-625, MU-626
The MU-623, MU-625 and MU-626 modules offer six digital input channels isolated from each other and other circuits of module (power supply and RS-485 interface) with high insulation strength.
The modules are designed especially for monitoring the state of digital signals with industrial signal levels (switches, etc.), additionally, the digital inputs are equipped with counters.
The modules are equipped (in addition to two standard LEDs for power supply and RS-485 line activity) with six LEDīs indicating the status of digital inputs.
