3 Phase Power PID Logic Enabled Temperature Controller



PID Logic Enabled Temperature Controller Panel – 3 Phase Power

CHR Inc’s PID Logic Enabled Temperature Controller Panel is designed for Higher Power heating applications which require more wattage.  Utilizing 3 Phase supply power makes perfect sense in reducing the amperage needed to deliver the needed power.

3 Phase PID Logic Digital Temperature Control System which features:

  • PID logic enabled Micro-Processor Temperature Controllers
  • Temperature Range to be easily programmed
    • Maximum allowable Set Point programmable
    • Staff ability to change Set Point within specified range
    • Lock-out possible
  • LED Display shows both Set Point & Process value
  • Step Down transformer
  • 3-phase Solid State Relay power output
  • Heat sink for heat dissipation
  • Sturdy Steel Enclosure – gasketed to be Weather-Proof
  • Plastic viewing window to read controllers
  • 100 Ohm RTD, virtually any type Thermocouple
  • Quick Disconnect Terminals to mate with Heater Power Cord
  • Power Cord – 12’ power cord to supply power, 3 wire

PID Temperature Controllers

3 Phase Digital Temperature Controller equipped with PID Logic, Auto Tune

This Temperature/Process Control Panel offers advanced control features for the most demanding temperature or process applications.  Each PID Controller is enclosed in a 1/32 DIN housing, the Process Control Panel is designed with dual, 4-digit LED displays for local indication of process value and setpoint.  Control methods include ON/OFF, PID, self-tune, and manual tune. PID control is supported with 64 temperature and time (ramp/soak) control actions. The dual loop output control allows simultaneous heating and cooling control. The second output can be configured as an alarm mode using one of the thirteen built-in alarm functions.  RS-485 communication is standard. Up to 247 communication addresses are available with transmission speeds of 2400 to 38,400 bps. The controller also features universal input, selectable temperature units (°F ,°C), selectable resolution, quick sampling rate and security protection.

  • Designed for Two Inputs and Two Outputs (possible to use only one)
  • Mounted in an aluminum enclosure with Extruded Sides
  • Utilize PID/Self Tune for accuracy
  • Staff ability to change Set Point if needed (maximum set point will be pre-set to prevent user errors)
  • Power output from Solid State Relays
  • On/Off Power Switch, Sturdy Rocker Style Switch
  • 10’ Power Cord
  • Equipped with EcoMate Quick disconnect terminals at the back of the enclosure to mate with CHR Inc. Heaters
