Product Brief:

13A0066G02 is Emerson Ovation series speed monitor module, upgraded successor of 13A0066G01, specially designed for steam turbine shaft speed monitoring in power plant. It receives pulse signals from magnetic speed probes installed on turbine shaft, converts pulse frequency value into actual rotating‑speed data and transmits to Ovation controller. It supports overspeed threshold judgment, can trigger alarm signal when rotating‑speed exceeds set value. Optimized signal filtering circuit strengthens suppression of field electromagnetic interference. 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。
