Brief Product Description

Emerson 5X00622G01 (former Westinghouse) is a 16-channel RTD resistance temperature detector input module for Ovation DCS distributed control system. It receives resistance signals from field RTD temperature sensors (such as Pt100, Pt1000), converts resistance value into digital temperature data and sends it to Ovation controller for monitoring and control. The module supports 2-wire,3-wire and 4-wire RTD wiring modes, with high precision resistance sampling and built-in signal filtering to suppress field noise. It has per-channel self-diagnosis function, can detect sensor open circuit, short circuit and circuit fault. Single-slot plug-in installation for Ovation I/O rack backplane, widely used for temperature measurement in power plants and process industries. Fully tested surplus and refurbished Emerson 5X00622G01 modules are available for legacy Ovation DCS maintenance, RTD temperature input module replacement and plant control system retrofit projects.

FAQ (Frequently Asked Questions)

• Q: Temperature reading abnormal or no measurement after installing 5X00622G01?
  A: Check RTD sensor and wiring, confirm 2/3/4-wire configuration matches DCS setting, inspect shielding grounding, check backplane contact, perform channel calibration and eliminate external thermal interference.
• Q: Does Emerson 5X00622G01 support hot-swap replacement?
  A: Hot swap is supported, but evaluate process monitoring risk before online replacement and perform lockout-tagout to avoid false alarm.
• Q: What system platform is 5X00622G01 used for?
  A: It belongs to Emerson Ovation DCS, 5X series RTD temperature input module.
• Q: What sensor types and wiring modes are supported?
  A: Mainly Pt100/Pt1000 RTD, support 2-wire, 3-wire and 4-wire connection.
• Q: Is Emerson 5X00622G01 available for new control projects?
  A: This legacy Ovation RTD input module is end-of-life for new installations. Only fully tested surplus and refurbished units are supplied for existing DCS system maintenance and retrofits.
