8 way 5V relay module for Arduino
5V relay module for Arduino and other microcontroller projects
This module has 8 x 5V changover relays with the option of using them through optocouplers. There is an LED for each relay to indicate when it has been activated.
The relay allows the low current microprocessor outputs to switch higher currents and voltages. With the optocouplers it fully isolates the live side of the relays from your microprocessor, this will require a seperate 5V supply to power the relays.
Trigger voltage : 5VDC
Supply Voltage : 5VDC (only needed if using optoisolators)
AC Switch ratings : 250V 10A
DC Switch ratings : 30V 10A
Size 134x52mm

8 Way Superior Metal Loudspeaker Switch 100W Per Channel
This switcher unit allows the distribution of a stereo amplifier. Simply connect the output of an audio amplifier to this unit and the output can then be distributed to up to eight different stereo speaker sets in eight different locations. Each speaker set can be individually activated via the push buttons on the front of the box. Ideally suited for buildings where an independent sound control is required for different rooms or zones.
Wiring Gauge 14 to 22 gauge
Input 1 x stereo
Output 8 x stereo
Power per channel 100W max.
Dimensions 432 x 125 x 55mm
Weight 2.08kg
