PAC-1I Analog Input Module

Feature & Principle

It samples standard analog signals from transmitters such as pressure, flow and level sensors. After isolation and A/D conversion, the signal is transmitted to the main controller via internal bus. Isolation design suppresses ground loop interference, supports range configuration and channel fault diagnosis, ensures stable collection of field process variables.

Specifications
