Description
Product Overview
The Emerson Ovation 5X00622G01 is a 16-channel RTD input module for the Ovation distributed control system. It measures resistance from RTD temperature sensors and converts resistance values to accurate temperature readings for the Ovation controller. The card supports multiple RTD sensor types and 2/3/4-wire sensor wiring configurations. It is widely used for boiler, turbine and balance-of-plant temperature monitoring in power generation, pulp & paper and water treatment facilities. OEM production has ended; available stock consists of surplus or refurbished tested replacement units for Ovation I/O racks.

Engineer Notes
- This is a fully integrated I/O module; no separate personality card required. Hot-swap can be performed when site lockout/tagout procedures are followed.
- Front panel LEDs indicate module health and per-channel fault states. The module detects open sensor leads, shorted wiring and out-of-range resistance values. Broken RTD wiring is the most common field fault.
- 3-wire or 4-wire wiring is recommended for long cable runs to reduce lead resistance measurement error. 2-wire configuration adds higher uncertainty and should only be used for short sensor cables.
- Use shielded twisted pair cable for all RTD wiring. Separate sensor cables from high-current AC power cables to reduce induced electrical noise.
- The module supplies low-level excitation current to each RTD. No external excitation supply is required.
- Apply ESD controls while handling. De-energize rack power before module removal or insertion if hot swap is not approved. After replacement, configure RTD type and wiring mode in the Ovation point database and calibrate each channel.
Pre-Shipment Test Protocol
- Visual inspection: Check PCB, edge connector, front panel LEDs and housing for bent pins, corrosion or component damage.
- Continuity and isolation test: Verify 1000VDC isolation between field RTD circuits and backplane logic.
- Functional bench test: Connect precision resistance decade box to each channel, inject resistance values corresponding to low, mid and high temperature points, confirm module temperature readings match reference values.
- Fault simulation: Simulate open sensor and shorted input on each channel, confirm module logs diagnostic alarms.
- Power cycling: Cycle backplane power 10 times, confirm channel readings remain stable after each restart.
- Save test logs and photos for QA records.
Buyer FAQ
Q: Can I swap 5X00622G01 directly with 5X00583G01 RTD module? A: Physical form factor fits the same rack slot. Confirm controller firmware and point database configuration. Verify RTD type and wire mode definitions before cutover.
Q: Does this module work for thermocouple temperature inputs? A: No. This module only accepts RTD resistance signals. Select thermocouple input modules for millivolt TC sensors.
Q: Is this new original Emerson factory stock? A: OEM production has stopped. Available units are surplus or fully refurbished tested stock. We offer a 12-month warranty on tested units.
Q: Are terminal blocks included? A: Terminal blocks are not included unless explicitly noted on your quote. Confirm terminal assembly availability at order placement.
