HCS Heaters Controls and Sensors Limit Controllers

Product Description

 

These FM approved Limit Controllers will shut down the process by disconnecting power from the process if the controller reads a value above setvalue for a Hi Limit Controller or below set point if configured as a low limit control. 

These Limit Controllers will remain in this state until the temperature has dropped below the set value and the reset button has been pressed. The control also has a timer to indicate the total time the setpoint is exceeded i.e. (duration of over temperature) it also has a register that will indicate the maximum temperature reached. Field programmable Low / High Process alarms and deviation alarms or band alarms are an option.

Limit Controllers Features:

  • FM approved Limit Controllers
  • Compact economical 1/16 DIN size
  • Easy to use, yet powerful
  • Time of over temperature condition indication
  • User selectable as high or low limit
  • Universal Inputs, Timer, Register, Retransmission, Communication
  • NEMA 4 IP65 Front Panel
