Wiring Diagrams
The following field wiring example shows how two isolated single-ended analog
actuators can be wired to the STB ACO 1225 module. Two separate external power
supplies are needed to make sure that the proper current is delivered to each
actuator.
2 outputs to actuator 1 (top) and actuator 2 (bottom)
4 field power returns from actuator 1 (top) and actuator 2 (bottom)
6 field power return (to the module) field power return (to the module)
