Honeywell SDW-550 5 Port Industrial Ethernet Switch

Product Overview

The Honeywell SDW-550 is a five port 10/100Base industrial Ethernet switch manufactured by Westermo. It enables communication between USI-0002 modules in the Control Processor and field devices, providing galvanic isolation and robust network segmentation.

Key Features

One 24 Vdc power connector and five isolated RJ-45 TX ports divided into two sections. Ports 1, 2 and 3 connect to the field; ports 4 and 5 connect to the CP backplane for enhanced surge protection. Complies with IEC 61010 standards with raised isolation levels between port sections.

Technical Specifications

Installation Guide

Mount the SDW-550 on a standard DIN rail. Ensure 55 mm rail length with 10 mm free space at each end. Connect ports 1, 2 and 3 to field devices and ports 4 and 5 to the CP backplane. Power via 12V 48V DC supply. Observe polarity on the 24Vdc power connector.

Engineering Advantages

Galvanic isolation protects the Safety Manager from network surges. Wide operating temperature range (25°C to +70°C) suits harsh industrial environments. Low power draw (max 320 mA) and compact footprint reduce cabinet heat and space demands. CE, TUV, UL and FM approvals ensure global compliance.

Frequently Asked Questions

Q1: Why are the RJ-45 ports divided into two sections?

A1: Ports 1, 2 and 3 connect to field devices; ports 4 and 5 connect to the CP backplane. This separation provides raised isolation and surge protection per IEC 61010.

Q2: What is the purpose of galvanic isolation?

A2: It protects the Safety Manager and control system from electrical noise and voltage spikes present in field networks.

Q3: Can this switch operate in cold environments?

A3: Yes, it operates reliably from 25°C to +70°C, suitable for most industrial and outdoor cabinet installations.
