USCA’s combine multiple functions into a single piece of equipment:

• Plug and Play adapters for optional signal conditioning.

• On-board flexible termination of process signals.

• On-board connection to Safety IOTAs.

• On-board Field power distribution.

• USCA receives 24 VDC power.

• Field disconnect.

• Field fuse.

• Probe points for testing.

• Digital Input with 5K resistor Adapter – FC-UDI501 is a single channel digital input module with a 5K

resistor for digital input devices without EOL. Output side interfaces with the field device and the input

side gets connected to safety system. This module does not require external power to operate.

• Digital Input Relay with 5K resistor Adapter – FC-UIR501 is a single channel relay input module with a 5K

resistor for wet contact applications. Coil side of the relay interfaces with the field device and the contact

side gets connected to safety system. This module does not require external power to operate

• Digital Input Relay Adapter – FC-UDIR01 is a SIL 3 single channel relay input module for low voltage

applications.

Coil side of the relay interfaces with the field device and the contact side gets connected to safety system.

This module does require external power to operate.
