Emerson KJ3243X1-BK1 S-Series Profibus DP Interface Card

The KJ3243X1-BK1 connects S-Series controllers to Profibus DP field networks through a dedicated interface card. This module handles high-speed cyclic data exchange between the control system and distributed devices. Engineers rely on this card for stable communication in continuous process applications.

Network Interface and Communication Ratings

The KJ3243X1-BK1 provides one Profibus DP port that supports transmission rates up to 12 Mbps. The interface handles up to 126 network nodes across a single segment. Furthermore, the card supports both cyclic and acyclic data services for flexible device integration. The module operates across a temperature range of 0°C to 60°C.

Physical Dimensions and Component Count

This interface card measures approximately 130 mm in length, 80 mm in width, and 25 mm in depth. The unit weighs about 0.18 kg, so technicians seat it quickly into the S-Series backplane. The assembly includes one Profibus connector, one backplane interface, and two mounting rails. In addition, front-panel LEDs show network status and fault conditions clearly.

Energy Storage Characteristics

The KJ3243X1-BK1 contains no internal energy storage components because it draws power directly from the chassis backplane. Therefore, the card requires no battery replacement and generates minimal heat. This architecture also keeps long-term maintenance costs low.

Integration Notes

System integrators pair the KJ3243X1-BK1 with S-Series controllers that manage Profibus DP device clusters. The single port design suits segmented networks where deterministic polling matters most. Consequently, engineers achieve predictable scan times across remote I/O stations.
