Overview
Configured for multi-channel RTD temperature signal acquisition in the Emerson Ovation Distributed Control System, the Emerson 5X00119G03 (5X00119G03 RTD Input Module) provides direct electrical conversion of resistance-based temperature signals into digital process data. The module accepts eight independent RTD inputs and supports 2-wire, 3-wire, and 4-wire sensor connections. Signal acquisition, sensor diagnostics, and channel processing occur within the Ovation I/O architecture.

Process Signal Acquisition and Channel Isolation
The 5X00119G03 processes resistance changes from connected RTD elements and converts the measured values into digital temperature information for the Ovation control system. Three-wire and four-wire connections can compensate for lead resistance effects more effectively than two-wire installations.
Each input channel operates as an independent measurement path. Therefore, field wiring practices should maintain separation between RTD circuits and high-energy conductors. Channel-to-channel isolation characteristics should follow the applicable Emerson Ovation hardware documentation for the installed system configuration.
The module also monitors field circuit conditions and reports open-circuit or short-circuit sensor conditions through its diagnostic functions.

Field Installation Guidelines
Install the 5X00119G03 in the compatible Emerson Ovation I/O hardware specified for the system configuration. Verify the module seating and connector engagement before applying or restoring field connections.
Route RTD cables separately from motor feeders, switching circuits, and other high-noise conductors. Use shielded instrumentation cable where required by the installation design. Terminate cable shields according to the site’s grounding architecture to avoid ground-loop currents.
Match the field wiring configuration to the installed RTD sensor type. In particular, maintain correct conductor continuity for three-wire and four-wire measurements. Verify sensor identification, terminal assignments, and diagnostic status before placing the associated control loop into service.
