Bag Filter Timer"has been designed to operate the equipments used for dust collection purpose in modern Industries. The Timer is wall mounting type and hazard free in operation. The"Timer is having a Power ON indication along with LEDs, which provide visual indication for energized relay for the selective solenoids. Once switched ON the controller operates the solenoid valves with a certain time duration (ON time) measured in milli seconds and with a preset time interval measured in seconds (Off time). The"Timer is designed with a facility of" RUN and TEST mode selection switch and CHANNEL selector switch. The"Timer is provided with two digital inputs, one for Remote Start and another for High Pressure . The"Timer is having 1 to 10 relays (2 relays for common and 8 relays for solenoids) for 16 solenoids. It has 2 fuses F1 F2. Fuse F1 is 250mAmps for transformer and fuse F2 is for solenoid input current. It is also provided one Relay output for Timer Running Indication. Safety measures: Enclosure IP55. Power Supply Card is fuse protected. All Solenoid Outputs are fuse protected. All Relay Contacts are surge protected by R-C Ckt. Specifications: No. of channel : up-to 16Nos On Time duration" : 50 milli seconds to 250 milli seconds Off Time duration" : 5seconds to 125 seconds Potential Free Relay output :" 3Amps for 220VAC / 10Amps for 24V DC for solenoid operation Solenoid Power Supply : 220V AC" ( 110V AC / 24V DC optional )" Controller input Power Supply : 220V AC +/- 10%, 50 Hz ( 110V AC +/- 10%, optional )" Enclosure" : Wall mounting type IP55 enclosure. Operating Temperature" :" 0 to 55 Deg.C Size" :300mm(W) x 210mm(H) x 150mm (D including canopy)
