Parker VMM2404 Controllers

APPLICATIONS

The VMM2404 is a general purpose controller for vehicles and other applications where the stabilized voltage is less than or equal to 32 Vdc.

The unit has 24 inputs and 8 outputs and a CAN/J1939 communications port.

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

Features

The VMM2404 is available in two versions. The controller has 9 dedicated digital inputs and 15 general-purpose inputs that can be configured as active-high or active-low signals.

The general-purpose inputs can be used as frequency inputs (2 AC-coupled and 13 DC-coupled) or to read analog voltages within 4 programmable ranges.

The 0837001 unit has an analog voltage range of 0-32 volts DC for 12 or 24 volt systems.

It can be used with 0-5 volt DC input signals but has a lower resolution.

0837002 The analog range is 0-16 volts DC and is primarily recommended for 12 volt systems.

This device provides high resolution for 0-5 volt DC input signals.

The VMM2404 has four high voltage side outputs with a maximum PWM frequency of 500 Hz and four low voltage side outputs that can be current sensed.

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

The system meets the stringent SAE J1455/EP455 environmental standards and advances multiplexing technology with enhanced diagnostic capabilities and Windows-based ladder logic programming.

The VMM2404 can be used alone or in conjunction with other multiplexing modules.

The controller is self-programmable and features LED status indicators for input, output, power and network activity.

Reliability

The VMM2404 continuously monitors its eight outputs for fault information. Faults detected include short circuits, overcurrents and open loads.

The VMM2404 allows the outputs to protect themselves electronically, allowing the system to reduce the number of fuses.

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

The VMM2404 has 30 red LED diagnostic indicators that can be used to display the status of inputs, outputs, power supplies, and the Controller Area Network (CAN).

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