WebRelay Users Manual
Section 2: Installation and Connections
Installation consists of mounting the WebRelay, connecting it to an Ethernet network, providing power,
and connecting the relay contacts to the device that will be controlled. Optionally, a control signal may
be connected to the optically-isolated input. The installation is completed by configuring the module
using a web browser.
The WebRelay supports connection to 10Mbps and 100Mbps networks. Although 100Mbps networks
are faster, the amount of data transferred to and from this device is very minimal and little if any
performance increase will be gained by setting it to 100Mbps. There are advantages however, to
operate this device at 10Mbps. At 10Mbps, less power is required, the unit runs cooler, and the lifetime
of the device is extended.
2.1 Installation Guidelines
•
This unit must be installed by qualified personnel.

property damage.
•
Do not use to directly control motors or other actuators not equipped with limit switches or other
safeguards to protect from equipment or wiring failures.
•
The WebRelay should be located in a clean, dry location where it is protected from the
elements. Ventilation is recommended for installations where ambient air temperatures are
expected to be high. See
Appendix H: Mechanical Information
for additional mechanical details.
•
The WebRelay must installed inside an NRTL certified industrial control panel or similar NRTL
certified fire/electrical enclosure.
•
If the WebRelay is used in a manner not specified by Xytronix, the protection provided by the
equipment may be impaired.
2.1.1 Wall Mounting
Mount the WebRelay to a wall by using two #8 screws. Attach the
screws to the wall vertically spaced exactly 2.5 inches apart. The
head of the screw should be about 1/10 inch away from the wall.
