Revision 2.6 WebRelay-Quad™ Users Manual
Section 1: Introduction
WebRelay-Quad™ is a compact, four-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-Quad™ using a web browser or a
custom application. Computers, PLCs, or automation controllers may control and monitor
WebRelay-Quad™ without user intervention. This works by sending text commands over the
network and reading XML status pages from WebRelay-Quad™, or by using Modbus/TCP
protocol.
WebRelay-Quad™ has many applications and is only limited by imagination. It works very well as
a stand-alone device that can be controlled using a web browser or as a convenient way to add
I/O to a computer. It can be used in industrial applications to control motors, lights, coils, pumps,
valves, etc.

1.2 WebRelay-Quad™ Models Available
WebRelay-Quad™ is currently available in two models. The only difference between the two
models is the power supply requirements.
Note: The WebRelay-Quad X-WR-4R1-I and X-WR-4R1-E have been replaced by X-WR-4R3-I
and X-WR-4R3-E respectively. These new models use the same firmware and are 100%
compatible with the original module. They use slightly larger relays which provide higher switching
current capacity.
Part Number Power Supply Requirements
X-WR-4R3-I 9-28VDC
X-WR-4R3-E Power Over Ethernet or 5VDC
