RS232 Relay Controller Board
RS232 Relays are equipped with firmware built into the board that will allow you to Control one relay at a time, a bank of relays or all relays at once with manual and automatic refreshing command set. RS232 Relay or Serial Relay Controller allows computer controlled switching using the serial port of your computer. An RS232 Relay supports any available COM port at any standard baud rate, allowing easy integration into any program that support serial communications. The RS232 Relay is ideally suited for applications that require data collection and control from a single device.ZRS Modules
The ZRS Module is offered with 3 different RS-232 connection options depending on the wiring option that best suits your application. The ZRS module is powered from the serial port of your computer. The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type Power Supply at checkout.
