Features

The VMM0604 has 6 general purpose inputs that can be configured as active high or active low signals.

In addition, they can be used to read analog voltages or as 6 frequency inputs (2 AC-coupled and 4 DC-coupled).

The VMM0604 has 4 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/EP455 environmental standards 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 VMM0604 continuously monitors its eight outputs for fault information.

Faults detected include short circuits (ground or power), overcurrents, and open loads.

The VMM0604 allows the outputs to protect themselves electronically, thus 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 VMM0604 has 12 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 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.

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.
