Our Serial Relays

Our industrial grade relay controllers all come equipped with a swappable communication interface. Simply select the relay controller you want and select a Serial module when you add it to your cart.  Our Serial Relay Controllers are the simplest and most reliable way to control electronics. Connect the RS-232 Module on the board to your computer or ECM. You can do this using a standard Serial Port or you can use a Serial to USB converter. Once its connected you can simply open a Serial Port (COM Port on Windows) and start 2-way communications.

Get started using our Free Base Station Software.  Base Station makes it easy to click a few buttons and start controlling relays in seconds without programming!

Serial Modules

We have three basic Serial Module options:

The first is a standard DB-9 connector. This connector is what comes to mind when you think of a Serial Connector.

The second is a 3-Wire Terminator. This interface is a simple 3 -Wire terminator for you Serial RX, TX, and GND. Recommended only for advanced users.

The third option is an off-board DB-9 connector. This allows more flexibility in placing the DB-9 connector in an enclosure.
