Emerson Ovation 1C31116G04 is analog input electronic module (EMOD) for Ovation DCS system. It collects multi-channel analog signals from field transmitters such as pressure, flow and level sensors, supports 4-20mA and voltage signals. It features high precision A/D conversion, wire break detection and channel fault diagnostics. It must pair with matching personality module (PMOD) for field wiring and signal conditioning, widely used for boiler and turbine process monitoring in power plants.

Emerson Ovation 1C31129G03 is analog output personality module (PMOD). It works together with analog output EMOD to provide field terminal wiring, surge protection and signal conditioning. It converts digital control commands from controller into standard 4-20mA analog signals to drive field control valves and positioners. With overvoltage protection and noise filtering function, it is applied in critical closed-loop regulating control circuits in thermal power units.

Emerson Ovation 1C31132G01 is digital input personality module (PMOD) for Ovation DCS. It is matched with digital input EMOD, providing terminal block wiring, signal filtering and group isolation for field discrete signals. It receives contact feedback from limit switches, equipment status relays and proximity sensors, suppresses contact bounce and electromagnetic interference. Commonly used for equipment status monitoring and interlock signal acquisition in power plant control systems.

Emerson Ovation 1C31219G01 is RTD temperature input electronic module (EMOD). It is designed to receive resistance signals from PT100 and other RTD temperature sensors. It provides high-precision temperature measurement, open circuit and short circuit detection, channel self-diagnosis function. Paired with dedicated RTD personality module, it is widely used for boiler metal temperature, bearing temperature and flue gas temperature monitoring in thermal power plants.
