| Note: | On TS-7250-V3 PCB Rev. B and older, the TS-RELAY8 relays will energize briefly immediately on poweron due to a hardware bug. This has been addressed in Rev. C and newer TS-7250-V3 hardware. When using older PCB revisions, ensure your application can tolerate several ms of the relays being energized at poweron. |
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:
This example assumes no jumpers are installed on the TS-RELAY8.
