PTI Access Controls PT 234A Circuit Board
 |
PTI Access Controls PT 234A MUX Board is a 16‑channel monitored‑line interface adaptor used to multiplex door alarm and sensor signals into a PTI access control system. Common failures include burned or tripped diodes on the line input/output traces, damaged relay contacts that lose the open/closed state indication, and corrosion or loose solder joints at the terminal block pins; power supply voltage excursions above 18 V can also damage the board’s ICs. Begin diagnostics by verifying the 12–18 V DC/AC supply to the board, inspecting the terminal block for proper polarity and secure connections, and checking each channel with a multimeter for continuity and correct EOL resistor values; finally review any error codes or status LEDs on the host controller that reference the MUX.[oss-gpt-20b] |
