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!

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):

Example use
Detect the device and display its properties.
$ sigrok-cli -d icstation-usbrelay:conn=/dev/ttyUSB0 --show
Driver functions:
Multiplexer
Scan options:
