8-bit IO

The TS-RELAY8 includes 8 SPDT relays. These are capable of switching up to 5A at 30VDC or 30VAC.

See sections of the TS-RELAY8 guide for register / jumper documentation:

WARNING: The TS-RELAY8 will energize relays immediately on poweron due to a hardware bug with this specific combination of hardware. Make sure your usage can tolerate this small flicker on poweron of several ms.

This example assumes no jumpers are installed on the TS-RELAY8.
