Source code | icstation-usbrelay |
Channels | 2, 4 or 8 |
Ratings | 10A @ 250VAC/30VDC, 12A @ 125VAC/28VDC |
Connectivity | USB/Serial |
The ICStation USBRelay is a USB relay card with up to 8 relays. Models with 2 (ICSE013A), 4 (ICSE012A) and 8 (ICSE014A) relays exist.
See Info for USB details.
WARNING: When reconnecting to the device (e.g. with sigrok-cli or SmuView) the connect will fail and the "query device"-command (0x50) will be interpreted as a bit mask and will turn on relays 1-4, 6 and 8. You have to power cycle the device to be able to reconnect!

Hardware
- STM 8S003F3P6 microcontroller: datasheet
- Prolific PL-2303HX USB to UART Bridge: datasheet
- ULN2803AG relay driver: datasheet
Protocol
The relay boards have a very simple and limited protocol.
Note: Once the device is connected and has entered the command mode (0x51), every following byte will be interpreted as a bit mask for switching relays. There is no way to leave the command mode!
Byte | Command | |||||||||
---|---|---|---|---|---|---|---|---|---|---|
0x50 | Query the device model.
Response:
| |||||||||
0x51 0xnn 0xnn ... | Start command mode.
Every following byte will be interpreted as a bit mask for switching the relays. 0 will turn a relay on, 1 will turn a relay off. Note: You cannot leave the command mode! Examples for switching mask bytes (ICSE014A, 8 relays):
