Product Brief:

1C31129G02 is Emerson Ovation digital input personality module G02 hardware revision works paired with 1C31127G01 electronic module

It is plugged onto I/O base together with host module defines 16 differential discrete input channels for field contact and switch signal acquisition

This personality module adopts differential input design effectively suppresses common‑mode interference for long‑distance field signal cables

It supports dry contact and 0‑60VDC wet input widely used for thermal‑process equipment status feedback under harsh electromagnetic environment

1000VAC channel‑to‑backplane and channel‑to‑channel isolation blocks ground loop interference and transient voltage damage

It transfers field discrete status to host electronic module for signal filtering and backplane data transmission

No extra software configuration required after correct physical installation host module identifies personality hardware automatically

Shares hot‑swap channel diagnosis and surge suppression features from matched 1C31127G01 electronic module

This is EOL discontinued spare part widely used for maintenance and renovation of thermal power plant Ovation DCS system

Please confirm matching host module model before purchase

Strict ESD anti‑static protection shall be followed during installation and replacement
