3.2 Digital Inputs - ICR/ICM SV1P Plus
3.2.1. Isolated Digital Inputs
The ICR/ICM SV1P Plus actuator has a total of 8 isolated digital inputs, which are
programmable. The isolated digital inputs can be configured to be either sinking
or sourcing. All of the isolated digital inputs have a common return and are
isolated from the internal circuitry. Figure 3-6 shows the circuit diagram for the
isolated interface.
