Ambetronics offershas introduced launched a digital time switch .At a given time or time set by users this digital time switch that automatically switches On and Off factory sirens, hooters, gong bells, etc, at a given time or time set by users. The unit has two independent channels hence with one unit two independent loads can be operated. The device has built in Ni-cd rechargeable battery Tto run the internal clock timing in case of power failure, the digital time switch device has built in Ni-cd rechargeable battery. The On/Off timings are stored in EEPROM memory Ffor more than 10 years the on/off timings are stored in EEPROM memory. The digital time switch device is very easy to use with help of only 3 keys and 6 LED, for CH-1, CH-2, RL1, RL2, On time and duration, on the front panel. The clock is in 24 hour format and the display is made of 5 digit 12.5 mm height 7 segment LEDs. Digital time switch The device is compact in size of 92 [W] x 48 [H] x 120 [D] mm panel mounting and it . It is widely used in factories, schools and colleges for automatic bell ringing, switch On/Off ovens, pumps, exhaust fans, compressors, neon sign boards, stair case and passage lights, home security by light control, etc. This device It is very useful in saving electrical energy by switching off the load during unwanted time.
