ATC9311 Analogue Controllers Description

ATC9311 is a micro-controller based analogue thermostat with a relay or SSR control output. The 3 digits indicator can be selected to display process or set value via button press. The controller is availabe for type J or K sensor input.

The controller comes with built in selectable On-Off or time proportional control and the output state of the relay is indicated by a LED. Setting of control temperature is easily performed through the knob on the front panel.
