Features:
- Provides sixteen independent relay output paths for AC or DC discrete circuits.
- Combines Size B compression terminals with conformal coating and CE compliance.
- Interfaces process-cabinet relay commands with externally powered field loads.
The ordered assembly is the coated CE relay output FTA with sixteen points. It is designed for the documented 120 V AC or 125 V DC field-circuit class.
Relay commands from the associated processor are presented as independent switched paths at the compression terminals. This gives cabinet technicians a defined location for connecting discrete process loads.
Service planning must identify every external source, the relay duty and the cable mapping before conductors are disturbed. The complete part number is critical because coating and approval variants are not interchangeable by appearance.
Supply is evaluated against the required voltage class, cabinet execution and exact part identity.

- Switches discrete actuators and solenoid circuits through independent relay contacts.
- Routes annunciation and interposing functions from HPM control hardware to field wiring.
- Supports maintenance of legacy process cabinets that retain the coated CE relay FTA.
- The -175 part number denotes the documented conformally coated CE execution.
- Externally powered relay contacts require individual source isolation before cabinet service.
- Field voltage, contact duty and site wiring rules must be checked before energization.
- Sixteen electromechanical relay channels translate processor commands into isolated switching paths.
- Each output reaches its assigned compression terminal without combining unrelated load circuits.
- The assembly draws 470 mA from the 24 V DC cabinet supply while handling field-side switching.
- The Size B footprint must align with the existing cabinet mounting and cable location.
- Recorded terminal numbers and load-source polarity should be preserved during changeout.
- Relay wiring must be checked against the processor allocation before the FTA is returned to service.
