Emerson KJ3201X1-BA1 DI Card Dry Contact

Description

The Emerson KJ3201X1-BA1 DI Card Dry Contact is a discrete input (DI) module designed for industrial automation systems. It is installed on DIN rails or card racks within DeltaV controller cabinets, not in field locations. Key technical specifications include support for up to 32 channels of discrete (switch) input signals, operating with 24 VDC, and specialized in dry contact signal reading—this means it detects contact open/closed states without supplying voltage to field circuits, delivering reliable, widely used DI performance.

The module features per-channel LED status indicators on its front panel, providing real-time visual feedback for each input to enable quick field fault diagnosis. It operates with a distributed architecture: instead of connecting directly to field wiring, it communicates via bus with CHARMS Electronic Modules (CEM), which interface with field wiring through CHARMS Plug-in Modules (CPM); a single KJ3201X1-BA1 card can manage multiple CEM units, and it also supplies power and management to downstream CEMs. Additionally, it supports DeltaV’s plug-and-play and automatic identification functionality via Electronic Device Description (EDD), streamlining integration into DeltaV control systems.
