Controlling the power circuits of as many as four separate devices is a snap with this Relay Phidget module. Each mechanical relay can control a seperate circuit of up to 1750W of DC power or 1750 VA of AC power. This module requires an external power supply, which is isolated from the VINT port in order to improve stability by preventing ground loops. The relays by nature also isolate the load circuit from the control circuit, meaning you don’t have to worry about voltage spikes in the load damaging your VINT Hub or computer.
AC or DC Switching
For DC applications, you can switch a circuit of up to 30V or 5A, as long as the switching power is 210W or less per relay (For example, 30V/7A or 21V/10A). Similarly, you can switch up to 12A or 277V AC, which happens to equal the maximum switching power of 2770 volt-amperes.
