Product Introduction
DY-400S Touchscreen Low-Voltage Transformer Switch, primarily used for converting standard thermocouples and platinum resistance thermometers, working thermocouples and resistance thermometers, and DC low-level signals during measurement. It can route any channel to the output through manual operation or standard interface control. The switch contacts have a very low thermoelectric potential (less than 0.2 microvolts). Easy to operate, it is an essential piece of equipment for automation verification (models with RS485 communication interface), calibration, and measurement systems.
【Main Application】
Used for on-site and laboratory verification, calibration, or testing of temperature, compatible with manual thermoresistor and thermocouple verification systems. Any input channel can verify standard resistors, standard thermocouples, standard platinum resistance thermometers, industrial platinum thermoresistors, industrial copper thermoresistors, thermocouples, and auxiliary instruments for various verification subjects.
【Operation Method】
Switch channels manually or via communication control.
When measuring resistance thermometers, you can switch between three-wire and four-wire measurements without the need for a second wiring.
This model features a communication interface (485 communication). With the accompanying supervisory software, digital multimeter, or our company's thermal automation calibration system control box, it can be upgraded to full automatic scanning. It facilitates desktop flat wiring and is intuitive and easy to operate.
Description: If the existing specifications and models do not meet your requirements, we can offer custom-made solutions for you.

Applications
Any input channel can be used to calibrate standard resistors, standard thermocouples, standard platinum resistance thermometers, industrial platinum resistance thermometers, industrial copper resistance thermometers, thermocouples, and auxiliary instruments for various test objects.
