MU-825, MU-826
The MU-825 and MU-826 modules are designed for monitoring the state of digital signals (switches, etc.) with industrial signal levels. Additionally, the digital inputs are equipped with counters.
The whole digital input group is isolated from other circuits of module (power supply and RS-485 interface), but inputs are not isolated from each other.
Note: In case of higher signal concentration, modules MU-32xxA series can be recommended.
