Switch Interface

Switch Interface (SI)

This unit is perfect for a programmer who wants to interface an electrical device to a central server.  The controller can be mounted away from the server and can be controlled by server commands sent via a standard http:// URL (see [SI Set-Up and Installation] for examples).

This is the perfect interface for anyone wanting to control up to four switches via a server connected to the same subnet.  

It can control anything that needs an on/off switch.  The relays are all SPDT so can be used to switch between circuits or turn any item on/off.  This could include lights, cooling systems, heating systems, ventilation systems or anything else that's controlled by a switch.

• Server can control each relay individually
