16x Isolated Solid State Relay Phidget

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

Product History

Date	Board Revision	Device Version	Comment
June 2017	0	102	Product Release
May 2019	0	110	Added failsafe timer functionality
April 2021	1	100	Added frequency control for PWM on ports 0-7
April 2021	1	200	Same as above; corrected device version number
August 2021	1	201	PWM frequency is now more stable across varying duty cycle; Improved general stability
April 2022	1	212	Failsafe now resets from any successful packet being sent Fixed a bug that occured when setting frequency from attach handler Fixed a bug where timers remained active after closing the channel
