Actuator Outputs
The proportional actuator driver outputs are 4–20 mA or 20-160 mA with a full
scale range of 0–24 mA or 0-200 mA. The SmartCore board has two proportional
actuator driver outputs, each output with source and return current readbacks.

Configuration Notes
•
Refer to Figure 6-8 for actuator output wiring.
•
4–20 mA or 20-160 mA signals are output.
•
See the specifications section for the maximum actuator output load.
•
Care should be taken to prevent ground loops and other faults when
interfacing to non-isolated devices.
•
Application software selects the actuator type, the output range, and the
dither amount.
•
The readbacks can be used in the application software for fault detection.
Avoid misconnection of the Analog Output (+) to the Actuator Output
(–). This will damage internal components, making the control
inoperable.
