DR5 Switch Controller
The DR5 Digital Remote offers additional logic input and
output ports, enabling the use of simple analog switch controls
in any HAL system. Lighted switch panels for room combine
applications are easily integrated into a HAL system using the
eight switch inputs and eight LEDs outputs on the DR5. Unlike
the HAL and DR4 Logic I/O, the DR5 Logic Out is intended
to drive the LED indicator on a room combine panel, and is a
writable parameter. The DR5 is designed to fit in a standard US
dual-gang electrical box, or mount directly near a room combine
panel.
