MeloAuto-Trusted PLC & DCS Parts Supplier
The KJ3242X1-BK1 intelligent interface module links field devices to DeltaV controllers through a dedicated communication path. Emerson designs this card for applications that require local signal processing before data reaches the controller. It handles protocol conversion and device diagnostics at the cabinet level.
Communication Ports and Channel Capacity
The module provides two independent communication ports, and each port supports up to sixteen field devices. RS-485 serial interfaces handle the field-side traffic at configurable baud rates up to 115.2 kbps. An onboard processor manages protocol conversion without burdening the controller. Additionally, per-port LEDs display traffic and fault conditions in real time.
Physical Dimensions and Power Details
The card measures 210 mm in length, 90 mm in width, and 45 mm in depth. It weighs roughly 0.45 kg, and it seats in a standard DeltaV carrier slot. The backplane supplies 24 VDC at a maximum draw of 0.8 A. Internal capacitors hold enough charge to complete a clean shutdown during brief supply loss.

Installation and Configuration Notes
Technicians seat the KJ3242X1-BK1 in its carrier slot and secure the rear backplane connector. Field wiring lands on the terminal block through shielded twisted-pair cable. Engineers configure baud rate and device addresses through the DeltaV configuration tool. Consequently, the module begins polling field devices as soon as the controller loads its database.
Why This Module Fits Intelligent Field Integration
Plant teams select the KJ3242X1-BK1 for its dual-port capacity and onboard processing power. Local protocol conversion reduces controller scan time and network congestion. The diagnostic LEDs shorten troubleshooting during device communication faults. This module suits refineries, chemical plants, and power generation facilities.
