Ignition and Inputs

The LMU-5000™ provides up to 7 High/low selectable inputs and one Ignition Sense

input.. These inputs are protected from typical vehicle transients and can be directly

connected to most vehicle level logical inputs from 4 volts up to the vehicle power input

level (typically 12 VDC). Their input impedance is approximately 10k . One of these

inputs is dedicated to sensing the vehicle's ignition status to provide for flexible power

management. The other seven inputs may be used to sense vehicle inputs such as cooling

unit operation, a hidden driver "Panic" switch, taxi on-duty/off-duty meter status or many

others.

The ignition input is pulled to ground through the 10k resistance, where the other inputs

can be configured to be normally High (i.e. pulled to +12v through a 200K10k resistor)

or Low (i.e. pulled to ground through a 100K10k resistor). The diagrams below show

how to connect the inputs in both a high- and low-biased configuration:
