Product Brief:

1B30023H04 is Emerson Ovation I/O branch bus terminator module, it is the upgraded hardware revision of 1B30023H02. It is installed at the tail end of Ovation I/O branch bus, equipped with 12‑pin bus connector for quick plug‑in connection. It provides precise terminal impedance matching for I/O communication bus, effectively eliminates signal reflection and oscillation generated on long‑distance bus lines, filters surge interference on the bus, ensures reliable data transmission between controller and each I/O module. Optimized hardware circuit enhances anti‑interference performance under complex field working conditions. It supports 24VDC redundant power supply to improve system operation reliability. On‑board LED indicators display power, bus running and fault status for convenient on‑site inspection and fault judgment. This is EOL discontinued spare part,widely used for maintenance and renovation of thermal power plant Ovation DCS system. Please confirm I/O base hardware version and bus branch layout before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement.
