The VMM1210 is a general purpose programmable logic controller (PLC) for
vehicle and other DC applications with steady state voltages less than 32V. It has
12 inputs and 10 outputs as well as a CAN/J1939 communication port.

This module is 100% compatible with other Vansco Multiplexing Modules.
The VMM1210 performs the following tasks:
Receives Digital/Analog/Frequency inputs:
The VMM1210 has 8 digital inputs capable of reading either active high
or active low type digital inputs. In addition, it has 4 inputs capable of
reading analog voltages, frequency values or active low type digital inputs.
Activates Outputs:
The VMM1210 has 8 high current (10A max) high side outputs. In
addition it has two low current (3A max) outputs capable of driving either
high side or low side loads, and can also be arranged in an H-Bridge
configuration. Outputs can drive any type of vehicle load including lights,
relays, solenoids, fans, etc.
Monitors Outputs:
The VMM1210 monitors its 10 outputs continuously for fault information.
Faults include short circuits (to ground or power), over currents and open
load. The VMM1210 allows systems to reduce the number of fuses by
allowing the outputs to protect themselves electronically.
