DPDT (Double Pole Double Throw) set of relay contacts
contact ratings - 5 amperes
Contains a DPDT (Double Pole Double Throw) set of 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, item #222, or item #224. 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 Relay Board
Item #555 - The expansion "Relay Board" is NOT supplied with a two pin mating harness (item #222, or item #224) to facilitate easy connection to the "EXP" connector provided on the Trak-DT family of boards. This way the standard DPDT relay is "expanded" to a 4PDT, thus doubling it's number of contacts. It also has two barrier strips to wire the relay contacts and coil. The relay contacts are rated at 5 amperes.
