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.
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
