WebRelay-10 Users Manual
Installation and Setup
2.2 Connections
CAUTION: MAKE SURE POWER IS SHUT OFF BEFORE WIRING!
CAUTION: THIS UNIT SHOULD BE INSTALLED BY A QUALIFIED TECHNICIAN.
MIS-WIRING OR MIS CONFIGURATION COULD CAUSE PERMANENT DAMAGE TO THE
WebRelay-10 AND/OR THE EQUIPMENT TO WHICH IT IS CONNECTED.
Relay connections are 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 until after
WebRelay-10 has been configured and tested. By doing this, wiring and configuration mistakes will not
cause the attached devices to turn on unexpectedly.
IMPORTANT: WIRES SHOULD BE PROPERLY CRIMPED TO THE CONNECTORS, AND
CONNECTORS SHOULD BE PROPERLY ATTACHED TO THE CIRUCIT BOARD OR RELAYS!
2.2.1 Power Supply Connection
WebRelay-10 requires power for its internal logic circuits. Connect a 9-28VDC power supply to the Vin+
and Gnd terminals. Note that a regulated power supply is recommended, such as a wall-mount AC-DC
adapter. Verify that the adapter is rated for the operating current of WebRelay-10 (See
Appendix H:
Specifications
for current requirements.)
Multiple WebRelay-10 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
Appendix H: Specification
s for current requirements.)
The power input tab terminals are 1/4” x .032”. Use UL listed quick-connect connectors suitable for field
connections. Use a suitable crimping tool as specified by the connector manufacturer. Use wire rated for
75ºC (min) for the power connections.
2.2.2 Relay Connection
Direct connection to relay contacts is provided through tab connectors located on the top of the relays.
Do not exceed the specified load ratings for relay contacts (see
Appendix H: Specifications
for load
ratings). The relay tab terminals are 1/4” x .032”. Use UL listed quick-connect connectors suitable for
field connections. Use a suitable crimping tool as specified by the connector manufacturer. Use wire
rated for 75ºC (min) for connections to the relays.
2.2.3 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 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-through” cable should be used.
