EMERSON KJ3207X1-BB1 Digital Input Module
EMERSON KJ3207X1-BB1
1. Overview
KJ3207X1‑BB1 is a 32-channel digital input module provided by Emerson for the DeltaV Distributed Control System (DCS). It adopts a Backplane-Board (BB) structure and can be directly mounted on the backplane of a control station or node unit. The module supports Fieldbus communication, enabling it to collect discrete signals from on-site switches, sensors, and other devices, and transmit these signals to the control system for real-time monitoring and logical operations.
