The REL1101 is a PWM-enabled solid state relay. The relay is great for controlling LED strips, DC motors, power relays, fans, and other small circuits. Solid-state relays switch silently and quickly, and last much longer than mechanical relays. This Phidget connects to your computer through a VINT Hub.

Features

Sixteen Solid-State Relays
Low-Side Switching - Each solid state relay switches to ground when enabled
Control power for a circuit or device up to a maximum of 30V and 8A
Pulse-width modulation - useful for dimmable electronics such as LEDs or fans
Controllable frequency for the pulse width modulation on ports 0-7
VINT connection is isolated, improving stability by eliminating potential ground loops
Failsafe Protection can be enabled to turn off the device if your program becomes unresponsive
