Emerson 5X00622G01 Ovation DCS RTD input module with 16 channels, supports 2/3/4-wire Pt100, Pt1000, Ni120, Cu10 RTD sensors, high-precision temperature acquisition for boiler, turbine thermal parameter monitoring, critical spare part for power plant Ovation control system.

Product Overview

• Part No: 5X00622G01
• Brand: EMERSON / Westinghouse Ovation

• Category: 16-Channel RTD Temperature Input Module 5X00622G01 is a high-density resistance temperature detector (RTD) input module developed for Emerson Ovation distributed control system. It collects resistance signals from field RTD temperature sensors and converts resistance values into accurate temperature data for Ovation controllers. Each channel can be independently configured for 2-wire, 3-wire or 4-wire sensor connection modes, compatible with mainstream RTD types including Pt100, Pt1000, Ni120 and Cu10. The module adopts automatic cold junction compensation and built-in linearization algorithm to guarantee stable measuring precision. Comprehensive channel diagnostics detect open circuit, short circuit and sensor abnormal faults to support equipment predictive maintenance. Hot-swap design enables online module replacement without interrupting temperature monitoring loops. Front panel LED indicators display module operating status and channel fault alarms for rapid field troubleshooting. Widely used maintenance spare for boiler flue gas, steam pipeline, bearing and generator winding temperature monitoring in thermal power units.
