The answer is yes! Or at least kinda yes.... The lowest coil voltage we offer on any of our relays is 10V like on the RIBU1C, but we do have our Low Input/Opto-isolated Relays. These relays can be found in our catalog by looking for the prefix in the part name "RIBTE" or "RIBME." The low input relays are great because while they still require a higher voltage for the coil, they have a separate input for a control voltage ranging from 5-25Vac/dc. Which means you can now control a 1/2HP motor with your Arduino or Raspberry PI.
Wiring Diagram
Here's a quick diagram showing how to drive a load with a 5V microprocessor and the RIBTE01B:
And that's not the only thing the low input relays can do! For example, if you have two control voltages ranging from 10-24V, a relay like the RIBTELC could be viewed as a logical AND gate relay. That means the load won't switch on unless both control voltages are present. The low input relays come in SPDT, DPDT, with manual overrides and with either a housing or modular version. So, a large variety of applications can be achieved with this series. As always though, if you're not exactly sure on how to go about your application, you can always call or email us here at Tech Support! We engineers are available Monday - Friday 8am-5pm, EST.
