8 way 5V relay module for Arduino

RM8

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 Stereo Speaker Selector 100W Per Channel

SSW8

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.
 
  • Enables eight pairs of speakers to be connected to a single stereo amplifier
  • Heavy duty push-buttons
  • Built-in overload protection
  • Spring clip terminals
  • Designed for 4-16 ohms speakers
 
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
