Prototrak 16269-1 Controller

Prototrak 16269‑1 is a CNC control board used in ProtoTRAK machine tools, handling motion sequencing, I/O routing and communication with drives. Common failures on this class of controllers include burnt or tripped power fuses, degraded MOSFETs causing over‑temperature shutdowns, and corrupted firmware from repeated power cycling; external RS‑232/USB interfaces may also fail due to loose connectors. First‑check steps: verify the 24 VDC supply voltage and current rating at the board’s input terminals, inspect for burnt components or cracked solder joints, and review any logged error codes via the control panel or diagnostic port. If power is stable, test all I/O lines with a multimeter and confirm firmware integrity by attempting a safe reboot or re‑flash if available.[oss-gpt-20b]
