The LIM 902, 404 regulators are simple and reliable analog regulators. The LIM 404 controller has an LCD display which shows the measured value. The set value is changed with a knob. The controller has a dedicated input for a J, K or Pt100 thermocouple. The 10A relay output allows you to control small loads without the use of additional contactors. The controller has a choice of ON / OFF control with hysteresis or proportional control P. LIM 404 can be additionally extended with an alarm relay 2A (option), which operates in the range of ± 10% of the set value.
