RC-4 Control Four Relay Contacts Across a Local Area Network

The RC-4 Network Enabled Relay Controller provides networked control of four remote relays via a web interface. The same interface can be used to check the status of four contact closures at the remote location.

Relays can be toggled on or off, or user-programmed timed closures can be activated. Two levels of user access permit selected users to have full operational and programming rights while others have operational control but not programming capability.
