Tecnetics Industries Inc. 21166701 LED Display Board
 |
The 21166701 is a Tecnetics Industries Inc. LED display board used as a PLC/add‑on module in industrial control systems. Common failure points for this class of boards include burned or cracked power input traces, damaged opto‑couplers on the I/O lines, and degraded LCD driver ICs that cause flickering or blank displays. First‑check diagnostics: verify 24 V DC supply voltage at the board’s VCC pin, inspect all connectors for corrosion or loose contacts, and run a continuity test across the LED driver traces; if available, review any error codes logged by the host PLC for I/O faults.[oss-gpt-20b] |
