Electrical characteristics of the inputs and outputs
4.5 Electrical characteristics of the inputs and outputs
Digital inputs
All digital inputs are galvanically isolated through opto-couplers. The electrical characteristics of the
inputs are:
Digital outputs
All digital outputs are galvanically isolated through opto-couplers. The electrical characteristics of
the outputs are:
The digital outputs have a fuse inside for protection against over-voltage (over 33 V DC) and against
reverse connection of the power supply.
Analog inputs
Use shielded cables connecting their meshes to the corresponding shield pin. All the analog inputs
have the following characteristics:
Analog outputs
Use shielded cables connecting their meshes to the corresponding shield pin. All the analog outputs
have the following characteristics:
