UR5BP3 -070N-1KC-2P1-Z

The Yokogawa UR5BP3-070N-1KC-2P1-Z is a Dual-channel Isolated Analog Output Module designed for the ProSafe-RS Safety Instrumented System (SIS).
This module acts as a critical interface between the safety controller and final control elements in the field, such as control valves (often equipped with positioners) or variable speed drives (VSDs). Its primary function is to receive a digital command value from the controller and convert it into a highly precise and isolated analog current signal (e.g., 4-20 mA) to control the field device.

Parameters & Specifications
Category Specification
Model Number UR5BP3-070N-1KC-2P1-Z
Product Line ProSafe-RS Safety Instrumented System
Function Dual-channel Isolated Analog Output
Output Signal 4 to 20 mA DC (with HOLD function on failure). The code 1KC specifies this analog current output.
Number of Channels 2 (Dual-channel, independent)
Load Resistance 0 to 750 Ω (for the 4-20 mA output range)
Isolation Channel-to-Channel and Channel-to-Backplane isolation.
Accuracy Typically ±0.1% of full scale (under reference conditions).
Power Supply Supplied from the node baseplate (24 V DC). The output power for the field loops is sourced externally.
Safety Certification TÜV Rheinland certified per IEC 61508 for use in SIL 3 applications.
Safety Function Output on Failure: The module is designed to drive the output to a predefined HOLD state (maintains the last output value) or a specified failure value upon detecting an internal fault or upon command from the safety controller. This is a critical safety feature.
Operating Temperature -40 °C to +70 °C (-40 °F to +158 °F)
Mounting Plug-in module for a N-Node or F-Node baseplate.
