Arduino Compatible 8 Channel Relay Board

These handy relay modules provide the easiest way to use your DuinoTECH to switch real world devices. Available in one, four and eight channel versions, these modules can switch up to 10A per channel. Includes back-EMF 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 DuinoTECH. While the one channel version operates directly from 5V.•    Status LEDs show channel status•    Active High logic•    Screw terminals for easy connection to relay contact.•    SPDT Relays•    Current Ratings:o    10A @ 250VACo    10A @ 30VDC•    Four mounting holes on each moduleCat No.      Channels    Supply Voltage      Optical Isolation          DimensionsXC-4419          1           5VDC                          NO                  40(W) x 27(D) x 18(H)mmXC-4440          4          12VDC                        YES                  77(W) x 55(D) x 17(H)mmXC-4418          8          12VDC                        YES                135(W) x 50(D) x 19(H)mm  For More info on Arduino.
