Product Brief:

13A0070H17 is Emerson Ovation series digital input module. It is responsible for collecting 24VDC on‑off status signals from field relays, limit switches and auxiliary contacts. Optocoupler isolation separates field circuit from DCS internal circuit to suppress ground interference. Input filter circuit filters out field pulse interference, improving signal stability. Each channel corresponds to status LED for convenient on‑site inspection. This is EOL discontinued spare part,widely used for maintenance and renovation of thermal power plant Ovation DCS system. Please confirm hardware revision and field signal voltage before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement。
