Description

RT228U combines two RT28U controllers in one 96×96 mm case. Thanks to its lower cost than the combined cost of 2 separate RT28U controllers, this model is often preferred when 2 technological parameters are controlled in one machine or installation or of separate adjacent processes. Typical applications are control of 2 temperatures, temperature and humidity, pressure and temperature, pH and temperature, and other combinations. Each of the 2 incorporated controllers is equipped with universal input and controls its relay outputs by an ON/OFF algorithm. Thanks to its programmable inputs and displays as well as relay duplex outputs (2 relays per controller, 4 relays per whole device), RT228U is a widely applicable device.
