Product Brief:
13A0066G04 is Emerson Ovation series speed monitor module, follow‑up iteration version of 13A0066G01 and 13A0066G02, widely applied in steam turbine shaft speed monitoring for thermal power plants. It receives multi‑group pulse signals from magnetic speed probes on turbine shaft, converts pulse frequency into actual rotating‑speed value and uploads data to Ovation controller. It supports overspeed threshold judgment and alarm output, adds signal cable break detection function. Optimized filtering circuit greatly improves anti‑interference performance under complex electromagnetic environment of power plant. On‑board LED gives visual feedback of power, channel running and fault conditions. This is EOL discontinued spare part,widely used for maintenance and renovation of thermal power plant Ovation turbine control system. Please confirm hardware revision and matching speed probe parameter before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement。
