ABB TP857 3BSE030192R1 Temperature Transmitter Base Unit

Product Description

The TP857 (Part Number: 3BSE030192R1) is a high-integrity industrial temperature transmitter base unit engineered for the ABB S800 I/O system and associated 800xA automation platforms. This module serves as a precision interface for process temperature measurement, converting low-level signals from field sensors into a stable, interference-resistant 4–20 mA current loop. It is specifically designed to meet the rigorous demands of continuous process monitoring where signal accuracy and long-term stability are critical for plant safety and efficiency.

Built with a focus on functional safety, the TP857 3BSE030192R1 supports high-resolution signal conditioning for both Thermocouple (TC) and Resistance Temperature Detector (RTD) inputs. Its rugged aluminum or stainless steel housing provides IP66/NEMA 4X protection, ensuring reliable performance in environments characterized by extreme temperatures, vibration, and electromagnetic interference. The module features advanced internal diagnostics and is SIL2 compliant, making it a standard component for Safety Instrumented Systems (SIS) in the global energy and chemical sectors.
