The analog returns (pin 4) for each channel are internally connected—therefore
there is no channel-to-channel isolation.
Sample
Wiring Diagrams
The following field wiring example shows how two isolated single-ended analog

required:
3 outputs to actuator 1 (top) and actuator 2 (bottom)
4 field power returns from actuator 1 (top) and actuator 2 (bottom)
