Time Activated Relays
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 control 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 USB Interface

USB Relay ZUSB ModuleBy selecting the USB interface you will be sending commands through the USB port of your computer to the board.  Boards on this page are equipped with a ZUSB communications module that adds USB communications to the board.  A command consists of a few bytes of data in numerical format usually between 2 and 6 bytes.  Once the command has been received, the controller processes the command and the relay activates.

Selecting a USB Relay Board

Below you will find the 4-channel USB Time Activated 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.  For more information on selecting the correct relay for your application see Choosing a Proper Amperage.
