Dual Relay Board

Dual Relay Board

MODEL: 3051_1B

SGD $ 32.00
Pre-Order
In Bulk
(per piece)

Connection to a Phidget InterfaceKit.Enclosure sold separately.

Note : Enclosure sold separately.

This board has 2 SPDT mechanical relays rated at 210W for DC or 1750VA for AC.

 

For new systems and projects, we recommend using the following VINT products instead of this one.

The Dual Relay Board allows you to control larger loads and devices like AC or DC motors, electromagnets, solenoids, and incandescent light bulbs.

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 1017 - PhidgetInterfaceKit 0/0/8.

Connection

This relay board can be controlled with Phidget digital outputs. For more details, see the Connection & Compatibility tab.

*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).

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.
