Velleman K8056 electrical relay Green

This relay card can be used in several ways : stand alone card, addressed by switches or open collector outputs or remote controlled through RS232. Since the card can be addressed using RS232 commands, you may write custom applications in any programming language on any platform.

- DIAGNOSTIC / TEST SOFTWARE:
- separate relay on/off test with moment or toggle function
- clear all / set all relays function

- 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 driving possibility using RX433N type module (not simultaneous with RS232) together with K8058 eight channel RF remote control
