The 4x Isolated Solid State Relay Phidget is a general-purpose controller suitable for a wide range of applications.
The relay outputs can control devices requiring substantial power, such as incandescent lights, high-power LEDs, relays, solenoids, motors, and more. Each output can switch up to 30VDC at up to 8A. The outputs act as a low-side switch to a shared ground, so the circuit you're switching will need an external power supply. The outputs support PWM with selectable frequency, allowing you to achieve finer control when needed. Each output is protected from transient voltages typical when switching inductive devices like relays, solenoids, and motors.
This device connects to your computer through a VINT Hub Phidget.

* Note: At switching powers powers higher than 50W, external cooling may be required. For high power applications, a hockey-puck style SSR may be more appropriate. See the "Other Relays" tab for more details.
** - PWM frequency can only be adjusted on firmware version 120 or newer. You can upgrade firmware by double-clicking on a device in the Phidget Control panel after updating to the latest version of our drivers.
