Product Short Description
Product Description
The ABB TR104 is a compact, high-performance, 1-channel DIN rail-mounted temperature transmitter designed for industrial process automation. It converts low-level signals from resistance temperature detectors (RTDs) and thermocouples into a standardized, isolated 4–20 mA analog output using two-wire loop-powered technology. This device serves as a critical interface between field temperature sensors and control systems (such as PLCs, DCS, and SCADA), providing galvanic isolation, signal linearization, and noise immunity to ensure accurate and reliable temperature measurement in harsh industrial environments. It is part of ABB’s T-series universal loop-powered transmitters, optimized for space-saving installations and easy integration into distributed control architectures.
