Working
Instrument accepts signals from Photo Sensors, Proximity Switches, Limit Switches, Contact closures, Encoders, Voltage Pulses etc. Instrument can work upto 2 KHZ of switching frequency. The Incoming signal is filtered, conditioned, wave shaped with help of filters and choppers. The signal is fed to Synchronous counter I.C. which drives seven segment display. At the same time signal is compared with set value. At the set point relay change over takes place. The Relay can be operated in Delayed On, Delayed Off, Auto Reset modes as per the application.
