Temperature Controller N440

The N440 is an ON/OFF action digital temperature controller which provides maximum versatility at an economic price and can be a great substitute for the obsolete analog controllers.
It accepts thermocouples type J, K or Pt100 RTD and features one relay and one voltage pulse output.
Keypad programming is simple and intuitive and parameters setting can be selectively locked.
The N440 is aimed at simple temperature heating or cooling processes applications that require low cost and yet demand good display accuracy with simple operation.
