Featuring solid-state relays, this relay board provides
a convenient way to switch low-current or medium-current signals in your project. It is also suitable for use in automated failure-injection
testing (e.g., short-open testing for sensor harness FMEA verification).
A solid-state relay (SSR) has no moving parts, is silent, has no contact bounce, does not require a particular minimum load current, and does not require a power supply for activation.
This board includes two SPST solid-state relays, driver circuits, and LED indicators.
Simply connect your logic-level signals to the inputs, and the relays are ready to use. The SSR outputs (contacts, or load-side connections)
are electrically isolated from the rest of the board, which allows the board to be used in a wide
variety of low-current to medium-current applications, including both AC and DC loads.
With this board, a logic-level signal (e.g., 3.3V or 5V) or higher-voltage signal (e.g., 24V)
may be used to control a solid-state relay.
Examples of logic-level signals include the outputs of an I/O card or a microcontroller's
output pins (e.g., Arduino or Raspberry Pi).

Mounting Options
These products are available in two different mounting variants. Product numbers ending with -DIN come
with DIN clips already installed and ready to snap onto 35mm or 32mm DIN rail. Product numbers ending with -FT
have stick-on rubber feet installed on the bottom side, allowing for benchtop use or panel mounting. For panel mounting, we suggest
1/4" nylon standoffs under the mounting holes, and #6 screws.
