Emerson KJ3241X1-BK1 S-Series Serial Interface Card

Description

The Emerson KJ3241X1-BK1 S-Series Serial Interface Card is an industrial-grade serial communication module designed for reliable system integration in automated processes. It operates at 220V, has an output frequency of 50 Hz, and holds CE certification. Equipped with RS-232, RS-422/485 (half/full duplex) communication interfaces, each port supports 32 data channels with electrical isolation between ports to prevent cross-interference. The module has a compact footprint of approximately 176 mm × 140 mm × 43 mm, weighs 1.2 kg, and offers IP20 (some models IP66) protection for suitability in varying industrial environments.

Key features include high reliability with low drift and built-in multi-protection for overvoltage, undervoltage, and overload conditions. It supports various logic operations, timing, and counting functions, and enables quick configuration in the DeltaV environment. Designed as a single-slot, 16-bit bus-compatible card, it adapts to multiple cabinet layouts and meets the ISA-S71.04-1985 standard for resistance to shock and vibration. The module integrates a logic processing chip, isolation circuit, and communication interface board, with a terminal block for field signal access (with protective cover), a metal heat sink for thermal stability, and mounting brackets supporting DIN rail or wall-mounted installation. It is compatible with multi-brand field buses including ABB, Rockwell, Schneider, and GE, and is ideal for applications in petrochemical, papermaking, food processing, power, metallurgy, and water treatment industries.
