4 Digital inputs.
You can record 4 digital conditions in the voltage range of 3..32V via optocoupler inputs.
Obviously safe.
The galvanic separation of the digital lines amongst each other and to the measurement system provides a perfect protection for the whole system. All in- and outputs are fitted with catch diodes to suppress electrostatic discharges.
Signal connection: Screw. Insert. Done.
