Cabling a digital input
Digital inputs are 4,5KV optocoupled
They can works with any
- push button
- deviator switch
- inverter switch
- NO output sensors
- NC output sensors
It is possbile to use shielded alarm or ethernet cable, working tension is 12V DC with a few mA current.
the number of required wires is:
common + number of inputs
so to cable 2 push buttons are required 3 wires, for 3 are required 4 wires and so on.
Any other detail like the kind of connected device or the system behaviour will be configurated via software.
