This relay card can be used in several ways : as a stand alone card, addressed by switches or open collector outputs or remotely controlled through RS232. This card can also be remotely controlled using RF (radio frequency) signals by using the 8-Channel RF Remote and a 455 MHZ receiver module. This card can also be addressed using RS232 commands, so you may write custom applications in any programming language on any platform.

8 high quality relay contacts: 5A/230Vac max. Relay outputs are transient suppressed using VDRs. LED confirmation on each relay contact. 8 drive inputs to use with open collectors or regular switches. RS232 input to drive the card with computer or terminal: baud rate: 2400, no parity, 8 data bits, 1 stop bit, high or low impedance selection (10K or 1K) Optional RF activation possible using RX433 type module and the 8-Channel Remote, (not simultaneous with RS232) Power output: unregulated 12Vdc / 200mA. Power supply: 12Vac / 500mA (including 12V output). Diagnostic software downloadable from the Velleman web site. Dimensions: 6.3" x 4.2" x 1.2"
