KL3103X1-BA1 Dry Contact Input Emerson

Description

The KL3103X1-BA1 Dry Contact Input Module is an Emerson industrial automation component, categorized as a discrete input card for use with DeltaV control systems. While direct technical data for this specific model is unavailable, it shares core functionality with the comparable Emerson KJ3201X1-BA1 discrete input card. Designed for installation on DIN rails or card racks within DeltaV controller cabinets, it is engineered to read dry contact signals without supplying voltage to field circuits, only detecting the open or closed state of contact points. It supports up to 32 channels of discrete (on/off) input signals, enabling high-density monitoring of field device statuses. Each channel features a front-panel LED indicator for real-time visual status display, simplifying rapid on-site fault diagnosis. The module uses a modular, indirect connection architecture: field wiring connects to CHARMS Plug-in Modules (CPM), which interface with CHARMS Electronic Modules (CEM), and communication with the card is handled via a bus. A single card can manage multiple CEMs, providing power and management to downstream CEMs, and supports DeltaV’s plug-and-play and automatic device recognition features for seamless system integration.
