Section 1: Introduction

WebRelay-10™ is a robust, 10-relay module with a built-in web server. It can be controlled and/or
monitored over any IP network including private networks, IP-based industrial control networks, and the
Internet. Users can operate WebRelay-10 using a web browser or a custom application. Computers,
PLCs, or automation controllers may control and monitor WebRelay-10 without user intervention. This
works by sending text commands over the network and reading XML status pages from WebRelay-10,
or by using Modbus/TCP protocol.
