4x Isolated Solid State Relay Phidget

Phidgets-REL1100_0

The REL1100 is a PWM-enabled solid state relay. The relay is great for controlling LED strips, DC motors, power relays, fans, and other small circuits. This Phidget connects to your computer through a VINT Hub.

Features:

  • Four Relays
  • Control power for a circuit or device up to a maximum of 30V and 8A
  • Pulse Width Modulation - rather than simply switching on or off, you can select a percentage duty cycle to limit the circuit power to a specific level.
  • Low-Side Switching - Each solid state relay switches an external circuit to ground when enabled

IFrame

Technical Details:

  • Quiet, quick and Long-lasting - Solid-state relays switch silently and quickly, and last much longer than mechanical relays.
  • Isolation - A Power surge on the load side of the relay will not damage the VINT Hub or computer
  • Failsafe Protection - Set the device to turn off automatically if your program becomes unresponsive

* 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.
