Car Battery Voltage Monitor C CAN CAN Bus interface
Car Battery Voltage can be monitored with the C CAN CAN Bus interface and control module.
C CAN can be configured to monitor the battery voltage on vehicles. Offering individual control of up to 8 outputs based on ba
ttery voltage, C CAN can be used for the staged shutdown of equipment as battery voltage lowers, leaving critical equipment on whilst maintaining the ability to still start the vehicle.
For Can bus controlled systems with no operator accessible on/off switch this feature gives automatic control over functions the operator of the vehicle has no control over.
Standard features include:
- Independent variable low voltage trigger setting for each of the 8 outputs.*
- Independent variable high (ON) voltage trigger setting for each of the 8 outputs.*
- Variable on off timing for both the low and high voltage settings for each of the 8 outputs.*
- 4 different selectable return to ON schemes if a low voltage condition is detected for each of the 8 outputs.*
- Battery voltage is above the preset high voltage.
- Battery voltage is above 13.6V on 12 V systems, 26V on 24V systems.
- Ignition is switched off and back on again and voltage is above the preset high voltage.
- Engine is running (CAN Bus detected RPM).
- For critical equipment, outputs can be set for on with no voltage monitoring control, ie: once on they remain on until switched off.
With C CANs ability to be tailored for different applications Battery Voltage Monitoring can be combined with other functions like “High Beam detect” for driving light control, “Park brake off with canopy doors open” for an alert output, “Run While Locked,” all from the one unit.
C CAN’s features are configurable by uploading a configuration file via its onboard serial port. Combined with an inbuilt CAN Bus sniffer this makes interfacing to new vehicles a simple process.
For customers wanting to tailor the module, we offer online support. This includes real time analysis of CAN Data, formulating a configuration file to suit your application, load and test. This service eliminates vehicle compatibility issues other manufacturers have and reduces turnaround times on new designs.
* 8 outputs are available on C CAN+ and C CAN+ HC only.
| Dual read only CAN Bus Interface monitoring up to 7 different CAN Bus functions. |
| User programmable interface for vehicle type ending vehicle compatibility issues. ie: Module is not locked to one vehicle type, but can be interfaced to most CAN Bus systems simply by searching that CAN Bus for the CAN Data string required and writing that into the modules Configuration file. |

| Create a multifunction control module controlling multiple peripherals in the vehicle using any of the outputs independent of each other. ie: Output 1 = VSS (Speed out). Output 2 flashing when the control switch at input 1 is on eg. for an LED indicator showing system status. Output 3 = Park Brake on. (Canopy door alert.) Outputs 4-6 combined = Ignition control. Run while locked. Output 7 = High beam on. Driving light control. Output 8 = brakes, park brake and accelerator pedal for antitheft. |
| Control outputs independent of each other with a logical output equation. AND, OR, NAND, NOR and invert 1-4 inputs to switch an output on or off. ie: Input 1 & Input 3 & Input 7 & Input 8 = output 2. Output 2 is on if all inputs = on. Output 2 is off if any input is = off. |
