TT-216 is an input and output galvanically isolated head mounted temperature transmitter, similar to other models we have, this model works with all thermocouple and RTD inputs, but to make sure your site are on the safe side, the isolation is incorporated in this transmitter, the input and range are also programmable via our computer and cell phone software.the input is configurable via PC and android cell phone.

MXD Series DIP-Switch Temperature Controller The MXD Series is a compact, panel-mount temperature controller that brings precision and simplicity to industrial and commercial thermal applications. Designed for fast, error-free setup, it features thumbwheel digital setting with 0.5% accuracy, eliminating complex menu navigation. Users can freely switch between ON/OFF and PID control modes via a front-panel toggle, with built-in LED indicators for real-time status monitoring. The controller delivers reliable performance with a 100ms sampling rate, 2,000VAC isolation, and robust heat tolerance, ensuring stable operation in demanding environments. Ideal for heat-sealing machines, shrink-packaging equipment, injection molding, HVAC systems, food processing, medical devices, and laboratory research, the MXD Series offers industrial-grade durability in a user-friendly package – where precision meets simplicity.  

This is a single phase SCR power regulators and temperature controllers 2 in 1 units, in a typical heating system, you would need a temperature controller and a SCR power regulators, and they are two separate devices, we go further and build this two devices in one package, this saves a lot of efforts for panel builders when it comes down to wiring, and RS-485 modbus is a standard feature, controller can be integrated to systems with HMI or PLC etc. the load can be directed wired to this thyristor power regulators, and it works with all kinds of inputs, Thermocuple, RTD, analog signal
