Temperature Controllers
ATC9311
Analogue Temperature Controller
The ATC9311 is a simple 3-digit, single-contact temperature controller with Fe-Const thermocouple input and simple analogue setting. The set value can be monitored digitally, and On-Off or time-proportional control is easily selected from the keypad. Deviation is shown in ±5 °C steps on the display. The device's operation can be easily monitored via the control output status LED.
