Input Connection (WebRelay-10 Plus™ only)
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 configured 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.
