To switch a load with the REL1101, connect the load and power supply to any pair of output and ground terminals, as
pictured to the right. The load could be a larger relay, a solenoid, LEDs, light bulbs, motors, etc. Check the speci cation
table on the product page for your Phidget to ensure that the voltage or current required by your load does not exceed
the maximum.
Switching Multiple Circuits
Multiple circuits with multiple supplies may be controlled by the REL1101 at the same time. Just be aware the grounds
of all switched circuits will be shared, as all ground terminals on the REL1101 are connected internally.
High Power Switching
The Isolated Solid State Relay Phidget is capable of switching loads of up to 240W. However, for power higher than
50W, you'll need some form of cooling to keep the heat of the transistors down at normal levels. This Phidget's
strengths lie in its multiple, high switching speed outputs. For high power projects, a hockey puck type SSR may be a
better choice.
