Smart Bi‐Directional Isolator Relay Delay with RV-C

00-01136-000

The Bi‐directional Isolator Relay Delay or B.I.R.D.® is a core piece of a DC Management System that
includes both a coach and a chassis battery. This electronic has 3 primary functions:

1) Bridging two battery banks together when a charging source is present from either one.
2) Isolating the batteries when the charging source is removed or when both battery banks are
fully charged.
3) Providing aux start power when the chassis battery is low and unable to start the vehicle.
