Product Description
Emerson 12P1731X072 KJ3201X1-BA1 Digital Input Module
Product Overview
- The Emerson 12P1731X072, also referenced as KJ3201X1-BA1, is a Digital Input Module designed for the DeltaV Distributed Control System (DCS) with S-series Traditional I/O. This module processes 24 VDC dry contact or high-side digital input signals from field devices, such as switches and relays, for use in process control applications. It is widely used in industries like oil and gas, chemical, and power generation, providing reliable integration with DeltaV systems through traditional I/O configurations.
