Digital Inputs
Tritex digital inputs are optically isolated from drive main power, but
have a common negative side. SIO and Ethernet options have 8 inputs,
the IA4 and CAN options have 4 inputs. They require a positive voltage
to turn on, so are compatible with sourcing outputs only. The voltage for
the input can be sourced from and external 24 V supply or from the
internal 24V supply. Each input can be assigned to any of the internal
input functions (see software section). It is important that the external
power source common is connected to PE.
