Outputs
The LMU’s outputs are designed to drive external relays. These outputs provide a high-current, open-collector driver that can sink up to 150 mA
each. These drivers may be used to drive external relays that can then control vehicle functions such as door locks, fuel shut-off valves, sirens and
lights. If additional current is required to drive the relays, external circuitry can be added to source the current. This diagram is a typical use of an
output to drive a relay.
