Product Brief:

1C31142G01 is Emerson Ovation compact contact input module G01 hardware revision for dry‑contact discrete signal acquisition

It is plugged onto matched I/O base unit directly collects contact‑closure status from field relays breakers and auxiliary switches

This integrated compact module combines electronic circuit and personality hardware no separate personality module required simplifies field spare‑part management

Built‑in hardware filter eliminates contact bounce interference improves signal stability under plant harsh electromagnetic environment

1000VAC isolation separates field contact side from DCS logic backplane blocks ground‑loop and transient surge damage

On‑board LED indicators display power communication and module fault status convenient for on‑site troubleshooting

The module supports hot‑swap operation can be replaced online without system shutdown for convenient site maintenance

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

Please confirm matched I/O base unit before purchase

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