5V solid state relays per channel 250V 2A, output with resistive fuse 250V 2A
8 channel 2 AMP Solid State Relay board Good for lighting- holiday displays etc
The input control signal voltage: (0-0.5V LOW solid state relay OFF) (2.5-20V high solid state relays ON)
Rated output load: 2A at 100 to 240VAC (50/60Hz)
Load voltage range: 75 to 264VAC (50/60Hz)
Load current: 0. 1 to 2 AMP
Power supply: 5VDC / 160mA (all channel ON)
Load type: General purpose
Isolation: Phototriac
Zero crosses: Yes
Use it to control various appliances and other equipment with large current.
It can be controlled directly by Microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
Product Dimensions: 155 x 55 x 24 mm
USE:
Very easy to use with an Arduino. Just needs 2 wires for GND + 3.3V and 8 wires for the 8 relays. You can use the newer Arduino that are in 3.3 V logic or a Raspberry Pi GPIO (also in 3.3 V logic) or any of the older Arduino (Uno, Mega) which are 5V.
These are zero-crossing PhotoTRIACs with snubber circuits. Their load rating is up to 2 A at 100-250 VAC.
Works fine with low-voltage 16 VAC too, for example, model train accessories power supply.
Module interface:
Input section:
DC +: positive power supply (by relay voltage power supply)
DC-: connect power negative
