Overview
The Emerson 5X00501G01 is a 16-channel analog input electronics module for the Ovation Distributed Control System. It processes 4-20 mA current-loop signals through a matching personality module and connects to the controller via the required 5X00497G01 four-slot I/O base. Furthermore, it provides 14-bit A/D conversion and internal diagnostics for open-loop, out-of-range, and auxiliary power fuse conditions.
Signal Processing and Channel Configuration
The module accepts 16 analog current inputs with a nominal range of 4-20 mA. It converts field signals into digital values for controller processing. Its 14-bit conversion resolution provides measurement granularity, while the complete-channel refresh rate is 200 ms for all 16 channels.
The conversion sampling rate depends on the selected power-frequency rejection mode:
- 50 samples/s with 50 Hz rejection.
- 60 samples/s with 60 Hz rejection.
The input impedance is 130 ohm +/-0.1%. Reference accuracy is +/-0.10% of full scale +/-0.5 LSB under the specified conditions of 25 +/-1 deg C, 50 +/-1% RH, and 0 V common mode.
Personality Module and Field Wiring
The 5X00501G01 works with the 5X00502G01 personality module, which supports the documented two-wire and four-wire transmitter arrangements. The personality module provides the field interface, while the electronics module performs analog signal conversion and channel processing.
In addition, the module provides 19.18 V transmitter loop power at 20 mA. Auxiliary power consumption differs between the two wiring arrangements, so the selected transmitter configuration must be considered when checking the power requirements.
Diagnostics and Electrical Isolation
Internal diagnostics distinguish open-loop conditions, out-of-range signals, and auxiliary-supply fuse faults. The documented open-loop detection band is 0 to 2.5 mA.
The module provides 1000 V AC/DC isolation between channels and logic. However, channel-to-channel isolation uses a common reference rather than independent isolation for each input. This distinction matters when evaluating field grounding and signal reference arrangements.

Configuration Requirements
The 5X00501G01 requires the following associated components for the documented I/O configuration:
- 5X00497G01: Four-slot I/O base required to accommodate the electronics module.
- 5X00502G01: Matching personality module supporting two-wire and four-wire transmitter arrangements.
Therefore, verify both associated model numbers when identifying replacement modules or checking an existing Ovation I/O assembly.
