Available in one, four and eight channel versions, these modules can switch up to 10A per channel. Includes back-EMF (ElecroMagnetic Frequency) protection and LEDs so you can easily see the state of the outputs. The four and eight channel versions even have optical isolation to protect your main board. The one channel version operates directly from 5V.
Features:
• Status LEDs show channel status
• Active High logic
• Screw terminals for easy connection to relay contact.
• SPDT Relays
• Current Ratings:
10A @ 250VAC
10A @ 30VDC
• Four mounting holes on each module

Poor documentation.
Missing schematic. Very poor documentation. From data sheet (if you can call it that): "Did you know: This module needs a 12V supply because a 5V USB power supply would not be able to operate 4 relays" Umm. NO. Its because the relays have 12V coils, not 5V coils.
12V not 5V
Unit works well. Beware this is a 12V board not a 5V one, so you need a 12v supply to run this. If you need a 5v powered one, that's what XC4441 is for. This unit is NOT superceeded by XC4440, they are 2 different products for 2 different uses
