Emerson SE4006P2 (KJ3241X1-BK1) DeltaV S-Series serial communication interface module, supports RS232/RS422/485 and Modbus protocol, gateway spare for connecting third-party PLCs and analyzers to DeltaV DCS.

Product Overview

• Part No: SE4006P2, KJ3241X1-BK1
• Brand: EMERSON

• Category: S-Series Serial Interface Communication Module SE4006P2 (KJ3241X1-BK1) is a serial interface communication module belonging to Emerson DeltaV S‑Series distributed control system. It acts as a protocol gateway to realize data exchange between DeltaV controllers and external serial devices including third-party PLCs, online analyzers, variable frequency drives and legacy equipment. The module is preloaded with Modbus communication driver, and supports additional industrial serial drivers for diversified device access. It is equipped with two independent electrically isolated serial ports configurable for RS232, RS422 full-duplex or RS485 half-duplex modes. The module supports hot‑swap online replacement and can be deployed in redundant pair configuration to improve system availability for critical control loops. Front panel LED indicators display module running status, port communication activity and fault alarms for convenient field troubleshooting. It serves as essential maintenance spare for renovation and expansion of petrochemical, power and water treatment automation systems.
