Description

SST‑SR4‑CLX‑RLL‑Serial Communication Module

1. Product Title

 SST‑SR4‑CLX‑RLL‑ ControlLogix Serial Gateway Module

2. Product Overview

The SST‑SR4‑CLX‑RLL is a plug‑in rack‑mount communication interface for Allen‑Bradley ControlLogix PLC chassis. Equipped with four independent galvanically isolated serial ports, it performs protocol translation between ControlLogix backplane tags and Modbus RTU / ASCII field devices. SST‑SR4‑CLX‑RLL eliminates the need for external third‑party gateway hardware, enabling direct data exchange with serial‑based instruments, drives and legacy controllers. Each channel can run as master or slave, with configurable baud rate and parity settings, simplifying integration of older serial equipment into modern Rockwell automation systems.
