T801 Light column display controllerDetailed product description：

The T801 light column display controller has functions such as display, control, transmission, communication, and universal signal input. It can be widely used in fields such as electricity, metallurgy, chemical industry, petrochemicals, paper printing and dyeing, brewing, tobacco, aerospace bases, etc.
By adopting the latest jumper free technology, the input port is equipped with universal signal input function. By changing the internal parameters, multiple input signals (various thermocouples, thermal resistors, remote pressure, mV, standard voltage/current signals) can be easily switched between, improving the versatility and reliability of the instrument.
Adopting high brightness LED digital display and high-resolution light column display (proportional display), the display of measurement/control values is clearer and more intuitive.
The input/output circuit adopts optoelectronic isolation, with strong anti-interference ability, and can be equipped with a serial communication interface. It can communicate bidirectionally with various serial interface devices to form a network control system.
It has multiple standard external dimensions and can be applied to various measurement and control scenarios. The whole machine adopts a snap in structure, which is very easy to install.
