Relay Output
The WebRelay has an internal high-current relay. Screw terminals are provided for the Common,
Normally Open, and Normally Closed contacts of the relay. The screw terminals are internally connected
directly to the relay with no internal fuse or other over-current protection. The relay contacts are isolated
from all other circuits.
Digital Input
The WebRelay has an optically-isolated digital input. The optically-isolated input provides electrical
isolation between the digital input and the low voltage control circuits of the WebRelay.
Power Supply
The WebRelay employs a switch-mode power supply which works from 9-28VDC. The model X-WR-
1R12-1I-E is an Ethernet powered device (PD) which receives power, along with data, on the twisted-
pair Ethernet cable. It can accept backup power on the Vin+ and Vin- terminals.
