4-20mA Power Plant Components Dry Type Transformer Temperature Controller RS485 Communication

DINKONDA GLOBAL Power Plants Special LD-B10-10 Series Dry-type Transformer Intelligent Temperature Controller, RS485 Communication And Standard 4-20mA Analog Current Output Function

Product Introduction
The LD-B10-10 series dry-type transformer temperature controller (referred to as the temperature controller) is an intelligent temperature controller designed specifically for the safe operation of dry-type transformers. It is designed and manufactured in accordance with the industry standard JB/T7631-2016<<Electronic Temperature Controllers for Transformers>>. Equipped with high-performance microcontrollers and other interface circuits, it has the functions of measuring, displaying, and real-time monitoring the temperature of transformer windings and iron cores; It has the functions of automatic start of cooling fan, switching between manual/automatic control of fan, timed start stop control of fan, and remote transmission of fan operation signals; It has the functions of over temperature alarm output, over temperature trip, and iron core alarm output, which can effectively distinguish fault signals such as sensor open circuit, ensuring that the temperature controller will not mistakenly send over temperature alarm or over temperature trip signals when the transformer is stopped or powered on; Equipped with a "black box" function that stores the measured values of each channel in case of power failure; Equipped with temperature simulation output function; Equipped with RS485 communication and standard 4-20mA analog current output function, it enables remote temperature and status monitoring.
