µCAN-BOX Family –
Reliability in Harsh Environments

MicroControl’s I/O modules of the µCAN-BOX product family provide the link for digital and analogue I/O signal networking on a CAN bus. The premium electronics of our µCAN modules facilitates connection of a wide range of sensors and actuators.

A/D conversion directly on the spot has significant advantages: due to their robust design the modules may be installed directly at the signal source – even in adverse environmental conditions. An additional control cabinet is not needed. The electronics of the µCAN-BOX series is tightly packed in a rugged aluminium casing (IP66 rated) protecting it reliably from dust and water. Signal wires may be connected via metric cable connectors or M12 plug-in connectors.

The µCAN-BOX Family

Improved compatibility

All modules are equipped with a high-speed CAN interface which supports both CAN 2.0A and CAN 2.0B, thus supporting the layer 7 protocols CANopen, J1939 and a multitude of vendor-specific variants. Module ID and bit rate are set via DIP switch or CAN bus.

For harsh environments

The µCAN-BOX modules are used in extreme conditons where reliable sensor and actuator technology is required:

  • Construction cranes and road construction machinery
  • Off-road and heavy-duty vehicles
  • Tractors and harvesters
  • Wind and solar power plants

Optimized design

Optical wave guides in the lid indicate the status of the device. For use in mobile applications, the electrical features are specified within a temperature range from -40°C to +85°C.

Easy diagnosis

All modules of the µCAN-BOX series feature easy diagnostics of the CAN state via two LEDs in the device.
