Sentex Systems 1100050 Keypad Control Board

Sentex Systems 1100050 Keypad Control Board is a compact access‑control interface that powers the MINI‑KEY keypad and relays door or gate commands to the main controller. Common failure modes include loss of power to the board (often due to a blown fuse or bad connector), non‑responsive key matrix (shorted contacts or burnt diodes on the keypad PCB), and erratic relay output caused by capacitor leakage or solder joint fatigue. First‑check diagnostics: verify 24 V DC input at the board’s supply terminals, inspect the keypad matrix for visible damage or corrosion, and test the relay outputs with a multimeter while cycling the keypad to confirm proper logic operation.[oss-gpt-20b]
