Users Manual
Section 2: Installation and Setup
Installation consists of mounting WebRelay-10
TM
, connecting to an IP network, providing power, configuring via a
web browser, and wiring relay contacts to the device that will be controlled.
2.1 Mounting
WebRelay-10
TM
can be be mounted to a standard (35mm by 7.55mm) DIN rail. Attach the module to the DIN rail by
hooking the top hooks on the back of the PCB card to the DIN rail and then snap the bottom hooks into place.
Remove from DIN rail using a flat-head screwdriver.
2.2 Connection
CAUTION: MAKE SURE POWER IS SHUT OFF BEFORE WIRING!
Connection to WebRelay-10
TM
is made through the ¼ inch male tab connectors. Mating connectors (¼ inch female
tab connectors) can be purchased at electrical supply stores.
It is recommended that the load (device to be controlled) not be connected to WebRelay-10
TM
until after WebRelay-
10
TM
has been configured and tested. By doing this, wiring and configuration mistakes will not cause the load device
to turn on unexpectedly.
IMPORTANT: MAKE SURE WIRES ARE PROPERLY ATTACHED (CRIMPED) TO THE CONNECTORS,
AND THAT CONNECTORS ARE PROPERLY ATTACHED TO THE CIRCUIT BOARD!
2.2.1 Power Supply Connection
WebRelay-10
TM
requires power for its internal logic circuits. Connect a 10-36VDC power supply to the
Vin+ and Gnd terminals. Note that a regulated power supply is recommended.
Multiple WebRelay-10
TM
units may be connected to a single power supply by connecting the power
supply input terminals in parallel. The power supply must have a high enough current rating to power all
units connected (see specifications for current requirements for specific model number).
2.2.2 Network Connection
Connect the Ethernet port to a 10 Base T or 10/100 Base T Ethernet connection. This typically connects to
an Ethernet hub, switch, or router. For configuration, WebRelay-10
TM
may be connected directly to the
Ethernet port on a computer using a “crossover” cable. Otherwise for connection through a hub or router, a
standard “straight-thru” cable should be used.
