Input Connection
Two discrete inputs can be connected to dry contact sensors or switches. Third party sensors can be used for
monitoring alarm conditions such as door access switches or transducer thresholds. Inputs can also be used for
operator switches and the unit can be congured such that they control the relays.
Figure 2.2d - Input Schematic
Connect one terminal of sensor or switch to the input terminal (Input 1 or Input 2). Connect the other terminal to
the ground terminal on WebRelay-10 Plus™. When contacts are closed the input is connected to ground and the
input is considered to be ON. Switch current is less than 2 mA.
