Emerson KJ3241X1-BA2 Serial Interface Module

Product Introduction

The Emerson KJ3241X1-BA2 Serial Interface Module is designed to provide reliable serial communication between control systems and peripheral devices in industrial automation. It serves as a bridge between Emerson distributed control systems (DCS) and field devices, allowing data exchange over serial protocols such as Modbus, RS-232, and RS-485.

This module enables robust data transfer with low latency, precise timing, and advanced error detection to ensure the integrity of signals in demanding process environments. It supports multiple serial devices simultaneously and integrates seamlessly with Emerson DeltaV and Ovation systems.

Product Parameters

Product Applications
