Our range of Micro-controller based PID temperature and process controller is dual heat/cool output in the form of DC pulse with direction control for motorised valves. 

Specifications:
DesignHigh-speed 8-bit microcontroller based with 12bit ADC/DAC
Temperature Sensor Input / Process InputThermocouple type J, K, R, S, B, C, D or RTD(Pt-100) 2 or 3-wire input. DC voltage, (4 – 20)mA. (Fixed / Universal in nature and it is user selectable using the keyboard in combination with a DIP switch.
No. of InputsSingle or Dual inputs
Temperature Range / Process RangeFull range of the specified input type. For process input the range is programmable from 0 to 3500 count or -2000 to +2000 counts with the facility to select the decimal point at 0.000, 00.00, 000.0 locations.
AccuracyBetter than ± 0.1% of the specified range.
Resolution0.1/1°C/unit
Sampling rate / Display rate40mS / 1 second
Indicating Accuracy+/- 1°C for Thermocouple +/- 0.1°C for Pt-100 and for other inputs – absolute to the input signal.
Display4 digits 0.5" /0.3” Red 7-segment display for process variable and Set Value.
Control Algorithm (User selectable)i) PID or ON/OFF selectable (when specified for switching output). Direct action or Reverse action (User selectable) 
ii) Dual heat/cool output in the form of DC pulse with direction control for motorised valves.
TuningAuto/Manual
Control Outputs (Switching)DC pulse 0 to 10VDC – 2 nos. External AC/DC SSR can be used to control final control device or forward /reverse valves)
