CAN Box 8FR-6

Programmable Power Supply Solution

CAN Box 8FR-6 is a programmable controller for power distribution for mobile machines and commercial vehicles. It enables power supply to multiple consumers and can also be used to control functions.

The CAN Box 8FR-6 contains:
  • Eight fuse and relay outputs with up to 15 A
  • Six high-side outputs with up to 2 A
  • Eight analogue inputs
  • Four digital or frequency inputs with switchable pull-up
  • Two CAN bus interfaces

All outputs are equipped with current measurement. The relays provide digital feedback of each output (NO/NC), allowing diagnosis of defective fuses or monitoring of relay status.

You can program ICCS CAN Box 8FR-6 with WEcontrol Designer. This IEC61131-3 compliant programming environment offers a wide range of PLC functionalities, software simulation and online debug over CAN.

  • Power supply of multiple consumers
  • Transmission of analogue signals on CAN bus
  • CAN-to-CAN gateway functions
  • Various diagnostic options (e.g. defective fuses, relay status, current measurement on all outputs, temperature measurements, etc.)
  • Load reduction of other control units by taking over the control of numerous consumers
  • Retrofitting of existing systems
