Time Delay Switch
The Reactor Relays are just that...a relay that reacts to a connected sensor or contact closure. Use that sensor or contact closure to trigger the relay or start a time delay so the relay will turn off automatically. Set a trigger point where a relay will trigger above or below that point. Set a range where the relay remains energized as long as the sensor level is in that range. Use a connected sensor or something as simple as a button to start a timer or sequence that you configure. Setup, configuration and manual control is done with the included Base Station Software.
RS-232 Reactor Options
The RS-232 Time Delay Relay uses a serial cable to connect to your computer to configure the board. Once configured the board will work on it's own or leave computer connected and take manual control of the board, read sensor levels and check the relay status.
4-Channel RS-232 Options
RS-232 Time Delay Relays are available with SPDT (single pole single throw) 5, 10 and 20 amp relays or SPST (single pole single throw) 30-amp relays installed.
Selecting The RS-232 InterfaceBy selecting the RS232 interface you will be uploading the time schedule to the board through either a DB9 or direct wire interface. Boards on this page are equipped with a ZRS communications module that adds RS-232 communications to the board. At checkout you will have three modules to choose from with either a DB9 or direct (3-wire) connection. 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 an RS232 Relay BoardBelow you will find the 8-channel RS-232 Time Delay 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.
|Find the board you need by using the interactive menu to he right. Hover over the Button and select the number of relays you want installed and then select the computer interface you need. Once there simply select the board with the correct amperage for the item you are switching.|
