Features:
- Provides eight individually isolated 4-20 mA input channels.
- Supports field-powered and locally powered current loops.
- Adds input conditioning and surge protection ahead of the electronics module.
The current ordering configuration is 1C31227G01, the current-input personality module used with Ovation electronics module 1C31224G01 for eight 14-bit channels.
It receives 4-20 mA field signals, supports either field or local loop power and passes conditioned data to the Ovation Serial I/O Bus through the electronics module.
Before commissioning, verify the exact electronics-module pairing, the loop-power source, terminal connections and single-point shield grounding for every channel.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Measures eight 4-20 mA process-transmitter loops in an Ovation I/O cabinet.
- Supports locally powered current loops supplied from the cabinet auxiliary 24 VDC source.
- Supports field-powered current inputs where loop power is provided outside the cabinet.
- The 4-20 mA configuration is the CE Mark-certified arrangement in this analog-input group.
- The cited certification applies to the documented current-input pairing, not the voltage-input variant.
- The installed system must retain the wiring and enclosure conditions referenced by the Ovation manual.
- Use shielded twisted-pair wire for every current-input field connection.
- Select the terminal positions for field power or local power exactly as shown on the module label.
- Bond the input return and cable shield at the cabinet or field device without creating a second grounding point.
- The subsystem is rated for operation from 0 to 60°C.
- Storage is permitted from -40 to 85°C before installation or service.
- Relative humidity must remain between 0 and 95% without condensation.
