- Sixteen software-configurable process-current outputs
- Two isolated output groups with protected circuitry
- Configurable safety response for communication interruption
DAO01 is the current-output interface used to deliver controller commands to analog field devices in a Freelance rack.
Its output architecture separates the channels into two isolated groups while providing overload protection and a defined response when rack communication is lost.
Match the backplane position, system cable, external supply, loop resistance and saved range settings before returning controlled equipment to operation.
Availability, condition, price, and shipping time for DAO01 are confirmed during quotation.

- Channel mapping follows the documented rack backplane and system-cable assignment.
- The first and second modules occupy different logical positions in a paired arrangement.
- Field-loop polarity and the selected current range must agree with the saved project.
- The application can use a defined safety current or retain the last commanded value.
- Safety behavior is established in the controller project rather than by module appearance.
- The selected response should be proven with the affected process placed in a safe condition.
- The receiving device and cable form one current-loop load that must remain within the module limit.
- External field power must be isolated before the module is removed from an energized rack.
- Commissioning should compare commanded current with the actual actuator or indicator response.
- Analog positioning commands for control valves and actuators
- Current-reference outputs for drives and process equipment
