Decalock-10-rm-0722 10 Channel Earth Interlocking System For Electricals Use

Decalock is specifically designed to monitor equipment’s earthing connection with the feasibility of stalling the equipment in case of a fault in the earth loop. The system consists of two separate units namely Main Unit and Interface Unit. The Main Unit continuously monitors 10 channels with a 5-seconds interval. The main unit communicates with the Interface Unit which is provided with an individual interlock for all the. 10 channels. When any channels earth loop resistance is more than 10 Ohms or faulty, the main unit communicates with the interface unit which engages or disengages the interlock, stalling the respective equipment until checked and corrected. Hence the name DECALOCK-10-RM-0722.

The main unit and interface unit have LED indication facility to determine which channel is/was faulty and what is the state of any relay at any given time respectively. The main unit is an S.S box consisting of a flame proof enclosure with a display window and two push buttons along with a 10+2 way terminal block for connections (Please refer to the block diagram). The layout of the display in the window of the FLP enclosure consists of 1 No. of 10 mm RED colored  LED display, 1 No. Of GREEN colored LED display, 1No. YELLOW LED, 10 Nos. of RED LEDs. The red and yellow displays show the channels earth loop status. It shows from ‘01’ to ‘10’ channels.
