Selecting The RS-232 Interface
By 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.

Below you will find the -channel RS232 Relay control that are available. The difference being the amperage of the relays installed and the type of relay.
