The 4x Relay Phidget is a mechanical relay board designed for a wide range of switching applications.

It includes four SPDT mechanical relays capable of switching AC or DC loads, giving you control over high-power devices such as incandescent bulbs, fans, pumps, and other more. It requires external power and includes a barrel jack connector that accepts from 8-30VDC.

This product features electrical isolation. This means the VINT port is isolated from the load, which can improve system stability.

The 4x Relay Phidget connects to your computer through a VINT Hub Phidget.

Features

  • Control up to four separate devices or circuits with SPDT relays
  • Rated for 210W of DC power or 1750VA of AC power
  • For DC applications, switch up to 30V at 7A
  • For AC applications, switch up to 12A or 277VAC (total power below 1750VA)
  • Electrical isolation


Note: This board is not suitable for switching signals. It takes at least 100mA of current to bridge the oxide layer that forms on the relay contacts, and most signals will not meet this requirement. If you need to switch signals, check out the Signal Relay Phidget or the PhidgetInterfaceKit 0/0/8.

*Note: Switching this relay at voltages higher than 30V will result in a reduced product lifespan.

Please Note: This relay cannot be switched at its maximum AC voltage and current at the same time. Ensure that total power of the load does not exceed the switching power for the relay. For example, you can switch this relay at 277V AC and 6.3A (1750VA), or at 145V AC and 12A (1750VA), but not at 277V and 12A (3324VA).

Cable Length Calculator

Estimated Relay Lifespan

The lifespan of the relays on this Phidget vary depending on how much current you're switching and whether it's AC or DC. The following graph illustrates the relationship between load current and relay lifespan:

FUNCTIONAL

The vertical axis is the lifespan of the relay (number of actuations) and the horizontal axis is load current in amps. As you can see, increasing load current from 5A to 10A can reduce relay life by more than half.

VINT Hubs

This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Overview page. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:

Phidget Cables

Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.

Power Supplies

This Phidget requires a power supply between 8 and 30V DC. We recommend that you use a 12V 2A DC power supply, since this is more than enough power to operate all four relays. Select the power supply from the list below that matches your region's wall socket type.
