Mining, Agriculture & Heavy Equipment
Configurable auxiliary power control and circuit data for mobile plant and agricultural machinery.
The challenge
Electrical downtime can disrupt production and maintenance plans.
Mining and farm machinery work in dust, vibration, heat and washdown, where an electrical fault can stop a machine.
Unplanned downtime
A single electrical fault can idle a machine and hold up the whole operation.
Harsh conditions and ad-hoc wiring
Vibration, dust and moisture can wear relays, fuses and add-on wiring over time.
Poor visibility
Without retained logs, intermittent electrical symptoms can be hard to reconstruct.
How Hardwire helps
Configurable auxiliary power control for mobile plant.
Solid-state switching
Solid-state outputs replace mechanical relay switching on auxiliary circuits.
IP67 enclosure
The PDM28 is rated IP67 and −55 to 90 °C (manufacturer specification).
Circuit data
Current and fault data for connected auxiliary circuits; remote monitoring not included.
Diagnostic logs
Logged circuit events that can help narrow fault-finding.
Typical applications
Where it’s used on the machine.
Candidate 12/24 V auxiliary circuits on mobile plant and farm machinery, subject to load limits and machine design approval. Hazardous-motion functions stay on circuits designed and approved for them.
Work lights
LED work and flood lights, with inrush checked.
Cab HVAC controls
Blower and control supplies in the cab.
Telematics
Fleet tracking, payload and monitoring units.
Camera supplies
Reversing and proximity camera power.
Selected valve-control interfaces
Only where the machine design approves it.
Other auxiliary supplies
Radios, beacons and dealer-fitted equipment.
