maintains relay position between trips and power cycles
requires momentary power to coil to operate and latch
contact ratings - 8 amperes
Contain a DPDT (Double Pole Double Throw) set of latching relay contacts. Designed to work in conjunction with the Dallee Signaling / Automation detection systems like the Trak-DT, Trak-DTT, Trak-DTT2, and Trak-DTL. They will also work with the Dallee Trak-DTRL but will require a 3 pin wire harness. Mating wire harnesses for the Trak-DT items are NOT supplied with this unit. They can also be used with other 12 volt switch control systems to obtain higher current outputs via the relay. The board measure 1.75" x 2" and contain two standoff's for mounting with #6 screws.
Dallee Electronics Latching Relay Board
The RELAY BOARD Latch consists of a Double Pole Double Throw (DPDT) 12 volt DC latching relay. The RELAY BOARD Latch has two input coils with a common connection to the "+" (B.6). It will latch any momentary input and remember that position. It can either be used with 12 volts DC coil power or by connecting to other DALLEE products with the appropriate optional wire harness.
When used as an expansion relay board to other DALLEE products, connect the two prong wire harness, item #222 or item #224, to the "expansion jack" (EXP) on the Trak-DT or other DT type board and each wire to the proper coil terminals of this board (shown on back). Only 1 red wire needs to be connected from the Trak-DT units but both must share the same 12v regulated DC.
When connecting to item #566, Trak-DTRL, you will require a 3 pin wire harness, item #223, or item #225.
