Ethernet Time Activated Relay
Set Time Schedule to Trigger Relays

Our Time Relays are equipped with firmware built into the board that will allow you to setup a time schedule to trigger relays.  The Time Relay series has an integrated Real Time Clock to control relays based on a time schedule (the board knows what day & time it is).  Connect these controllers to the serial port of your computer to setup the time schedule & upload it to the board.  Once stored, the computer is no longer needs, and the relays will activate according to your schedule that can be as simple or as complex as your application requires.

Time Schedule Control

Events are scheduled times when a relay or group of relays are turned on or off.  They are defined by the user first by time: Year, Month, Day of Month, Day of week, Hour, Minute, and Second.  You have the ability of switching relays on or off at very specific times.  You can add up to 1000 Events to the list.

Selecting The Ethernet Interface

Lantronix Ethernet Module ModuleBy selecting the Ethernet interface you will be uploading the time schedule to the board through your local area network or internet.  Boards on this page are equipped with a Lantronix communications module that adds Ethernet communications to the board.  The board will plug directly into your router where it is assigned an IP address.  Once the IP address has been assigned the board can be discovered on the network using the included Base Station software.  Using Base Station you can configure your time schedule and upload it to the board.

Selecting an Ethernet Relay Board

Below you will find the 4-channel Time Activated Ethernet Relays that are available.  The difference being the amperage of the relays installed and the type of relay.  Choose the controller that fits the amperage you are switching.  You will find SPDT relays in the 5, 10 and 20 amp versions and an SPST version in 30 amp.  A solid state version is also available.  For more information on selecting the correct relay for your application see Choosing a Proper Amperage.
