Add 16 PWM-enabled solid state relay outputs to your hub. This module is isolated from input to output.

Compare

For applications that require a ton of outputs, the Isolated Solid State Relay Phidget is the module that you are looking for. With sixteen PWM-enabled relay outputs, not only can it handle orindary logic-level devices at 3.3V or 5V, but it can also be used to control devices of up to 30V volts and 8 amps. LED strips, DC motors, power relays, fans and other small circuits are all common loads for this type of output.

SKU: REL1101_0

Externally Powered

Instead of providing power to the device, a solid state relay output switches the circuit to ground and completes the circuit when you want to switch it on. The power is supplied externally and should be connected in series with the load and the relay output. Each channel has a ground terminal beside it to make wiring a snap, and each one leads to a common ground.

PWM Switching

In addition to switching at microsecond speeds, each relay output is also capable of pulse-width modulation; rather than simply switching on or off, you can select a percentage duty cycle to limit the power being supplied to a specific level. This allows you to control devices like a dimmer would, which is an important feature for LEDs, fans, and motors. Check the datasheet for your device to ensure that it is designed to be used with PWM (some devices such as incandescent or CF bulbs are not designed for dimming).

Isolated for Stability

The VINT port on this board is electrically isolated from the rest of the board, improving stability by eliminating ground loops.
