Highlights

  • More reliable than fuse and relay technology
  • 12 high current (15A) outputs
  • 12 digital and 8 analog inputs
  • Compact, sealed, robust enclosure
  • Enhanced diagnostics and protection
  • 5 V sensor supply
  • Adjustable over-current setpoint
  • Output current feedback

Overview

The Power Distribution Module (PDM) expands CAN bus control networks by replacing existing relay and fuse boxes with more reliable solid-state switches that can directly drive work lights, wiper motors, cooling fans, directional DC motors and other high current loads. The I/O is multiplexed using a CAN bus network which greatly simplifies the wiring harness for ease of installation and improved reliability. For applications not requiring a CAN bus controller, the inputs can directly trigger the outputs so there is no need for a separate controller.

Each of the 12 IX3212 outputs can switch or proportionally control up to 15 A loads in 2.5 A increments and feature built-in over-current detection and shut-down capability. Outputs are paired to run up to six electric motors with H-bridge direction control. Twelve digital inputs monitor switched battery, ground and floating inputs. Additionally, eight analog inputs are available with a 5V sensor supply. The enclosure is fully sealed and potted to withstand wash down and protect from dust.
