Product Description
Overview
The Emerson KJ3001X1-BA1 is an 8-channel digital input card engineered for DeltaV S-Series control systems. It provides isolated 24 VDC dry contact inputs, enabling reliable monitoring of industrial devices such as switches, relays, and contactors. Isolation protects the system from ground loops and electrical noise, ensuring consistent and accurate signal acquisition.
