Standard PID or Fuzzy Logic Control Mode (keypad selectable)
Lockout of keypad operation of all except set point
Settings for min. and max. temperature set point
Heat or cool mode
14 bit resolution
Universal AC power 85-265 VAC
Nema 4 Front Panel
Alarm relay control output 3A @ 250VAC
Remote Set Point - 4-20 ma from remote control computer, PLC, etc. keypad selection of control of set point from front keypads or remote 4-20 ma signal.
4-20 ma transmit output of process temperature for remote temperature indication.
2nd output - relay or 4-20 ma output for heat/cool applications or control of two independent heating loads from single set point.
The Fuzzy Logic controller is available with either a proportioning zero crossover or phase angle controlled output to operate a back to back SCR arrangement. This option adds to the base price and provides terminals for two sets of Gate/Cathode connections on the rear of the instrument. This provides a more advanced type of power control than the SSR output option for control of a solid state relay (SSR), and is more economical than using the 4-20 ma output to control a standard SCR Power Controller.
Same as previous option but provides 3 sets of Gate/Cathode connections for operation of a 3 Phase SCR-Diode load..
