RT28U is a low-cost multifunctional
programmable controller. Its universal
input accepts the most common RTDs,
thermocouples, and linear signals.
The device can be equipped with up to 2
relay outputs, which can control various
actuators using ON/OFF control algorithm,
and the optional RS485 interface enables
networking. RT28U allows adjusting
of the built-in digital filters
and the programmable output delay,
resulting in increased operation reliability
in case of industrial interferences.
