The TS0843 provides 4 double pole, double throw relays to activate physical devices from either positive or negative level sensitive triggers.
The TS0843 can be used as a whole unit of 4 relays or snapped apart along deep ridges pressed into the board to be used as single or double relays. When used as a set of 4, a power track running the full length of the board provides common power across the relays from a single power connection.
Relays can be connected to anything which is electrically controlled eg. lighting circuits, air conditioners, pump motors & generators etc.
