Product Overview

The ATD5A-00 is a DIN rail mounted head-mount temperature transmitter designed to convert resistance temperature detector (RTD) resistance variation into standardized 4–20mA proportional analog signals for industrial process temperature monitoring and closed-loop control. This signal conditioning module isolates weak sensor input signals from field electromagnetic interference, stabilizes temperature reading transmission over long cable distances, and eliminates measurement errors induced by lead wire resistance drift in field wiring loops.

It supports direct connection to Pt100 RTD sensors, with configurable measuring ranges via simple on-site parameter setup, and delivers consistent, repeatable readings for critical thermal control points. Process control engineers, instrumentation maintenance staff and system integrators gain practical advantages from its narrow modular DIN rail footprint that conserves cabinet space, built-in surge and reverse voltage protection, and stable performance in continuous 24/7 plant operation. The standardized 4–20mA output seamlessly interfaces with all mainstream PLC, DCS and local indicator panels, simplifying system integration for heating, cooling, reaction vessel and fluid thermal regulation processes across multiple industrial sectors.
