Apollo IO Card Chip RM56258114 12785575 Sealed Connector Plug and Play Module For Paver

Replacement part for RM56258114 / 12785575 / 56258114 — built for fast on-site swap and stable signal throughput

• Sealed multi-pin connector interface — the plug face is protected against grit, wash-down water and diesel splash, so pins stay clean when the cabinet is opened on site.
• Plug and play replacement — no rewiring, no re-pinning, no parameter reload. Unplug the failed board, seat the new one, close the cabinet and resume paving.
• Corrosion preventive conformal coating — the board surface is coated to resist humidity, salt spray and condensation cycling between night and day shifts.
• Stable digital I/O signal path — shielded routing and soldered joints keep switching noise away from sensor readings for feeder and propulsion control.
• Matched to genuine Apollo part numbers — RM56258114, 12785575 and 56258114 are cross-referenced on the label so your maintenance team can verify the fit before installation.

The card sits in the paver's main electrical cabinet and works as the hand-off point between field sensors, the control modules and the operator panel. Signals from the screed, feeder and travel circuits arrive at the board, are conditioned, and are passed on as clean commands. Keeping that chain intact is what protects paving tolerance and daily output.

• Operator display shows control or communication errors that clear after a restart
• Screed heating responds late or runs unevenly across the width
• Feeder or conveyor speed drifts without a change in setting
• Functions drop out when the machine is hot or after a wet shift

If two or more of these appear together, inspect the cabinet connectors first, then confirm the IO card before ordering deeper electronic parts.

Switch off the machine and isolate the battery before opening the cabinet. Photograph the connector layout, release the locking tabs, and seat the replacement board fully until the tabs click. Confirm grounding, close the cabinet and run a short function test on screed heat, feed and travel before returning to the job site.

Stock is held for single-piece orders as well as fleet replenishment, with dispatch in 7–10 days and packaging in an anti-static bag inside shock-proof foam and an export carton. Paver configurations vary across build years, so send your machine model and the number stamped on the old board and our parts team will confirm the match before shipment.
