TEMPERATURE MEASURING INSTRUMENTS / TEMPERATURE CONTROLLERS
 TEMPERATURE CONTROLLER-2020D(1)

Digital Temperature Controller- 2020D

Setpoint and process both are displayed simultaneously. The process display is 12.5mm height.
The setpoint display is 8mm height. The power supply is 90-260 VAC.
NOTES
1. ON-OFF Control: Relay is on upto the set temperature and cuts off at the set point. System temperature will come down and again relay will go on at temperature 2 °C below the set point. Same function is repeated. Adjustable dead band is provided for specific application. Time-Proportionating Control : Relay will be ON and OFF in band of ±2 °C of set-point. ON-OFF : time will adjust as per the heat requirement of the system. Of course total time cycle will be of 15 seconds.
2. 4½ digit Temperature Indicator/Controller Nippon 2020A.
3. Contact factory for supply volts of 90 – 260 VAC & retransmission output

Principle
 Input signal is signal conditioned, linearised and amplified.  It is compared with the set point and accordingly relay operates.
Inputs  J,K,R,S,T and other thermocouples, R.T.D's like Pt-50, Pt-100 (2~3 wire), 0-1VDC, 4-20 mA... Etc.
Range, Indicating  Refer Table - A
Accuracy, Resolution Ambient Compensation Automatic
Setting By push button - COARSE/FINE pots or by membrane key - trimpot
Setting Accuracy Better than 0.2%
Output  Relay contacts rated at 230V/6A.
Control ON-OFF or Time-Proportional (Refer Note on back side)
Sensor Open Protection  Built-in Indicates ' 1', Relay cuts-off.
