APPLICATIONS

The VMM3120 is a general-purpose controller for vehicles and other applications where the steady-state voltage is less than or equal to 32 Vdc.

It has 31 inputs and 20 outputs and two CAN/J1939 communication ports.

The module is fully compatible with other Parker Vansco multiplexer modules.

Features

The VMM3120 has 17 digital inputs. The digital inputs are used to read high level active signals.

Two of the inputs can be used for power control.

In addition, it has 10 inputs that read analog voltages and 4 frequency inputs (2 AC-coupled and 2 DC-coupled).

The VMM3120 has 16 high voltage side outputs with a maximum PWM frequency of 500 Hz and 4 low voltage side outputs with current detection.

The outputs can drive any type of vehicle load, including relays, solenoids, fans, and more.

The system meets the stringent SAE J1455 environmental standard and advances multiplexing technology with enhanced diagnostic capabilities and Windows-based ladder logic programming.

The unit can be used alone or in conjunction with other multiplexing modules.

The multiplexing system is designed to simplify and reduce troubleshooting, maintenance and documentation time for electrical systems.

The modules are self-programmable and feature LED status indicators that show the status of inputs, outputs, power supplies and network activity.

Reliability

The VMM3120 continuously monitors its 20 outputs for fault information. Faults detected include short circuits (ground or power), overcurrents, and open loads.

The VMM3120 allows the outputs to protect themselves www.abb-drive.com electronically, thus allowing the system to reduce the number of fuses.

In the event of a fault, the device disables the output where the fault occurred.

On-board diagnostics allow for easy troubleshooting, and the auto-programmable module saves time and maintenance costs by keeping module and program inventory to a minimum.

VMM users appreciate the module’s rugged design as well as the stringent industry environmental requirements and communications (SAE J1939) standards.

All of these features make the controller easy to integrate into any on- or off-highway vehicle.
