Temperature Controllers
AT411
Analogue Temperature Controller
The AT411 is a conventionally designed, single-contact temperature controller with Fe-Const thermocouple or Pt-100 resistance thermometer input and simple analogue setting, capable of On-Off or time-proportional operation. The device's operation can be easily monitored via the power LED and the control output status LED. Its 8-pin socket or plug-in terminal block connection makes installation and service easy.
