Ondyne 70190-21 Dew Point Controller
 |
Ondyne 70190‑21 is a dew‑point controller used in industrial moisture‑control loops, featuring a temperature‑humidity sensor, PID logic, and alarm outputs. Common failure modes for this class include sensor drift or breakage, power supply degradation (especially the 24 V DC rail), firmware corruption, and relay/contact wear on the output stage. Initial diagnostics should verify the input voltage to the board, check continuity of the sensor leads, and review any error codes displayed on the panel or communicated via Modbus/serial interface.[oss-gpt-20b] |
