5V 2-Channel Solid State Relay Board

A relay is an electrical component used to switch high-current devices using low currents. This relay can be used with alternating current (AC).

Solid State Relays (SSR) differ from other relays in that they use a triac and do not have mechanical parts. As a result, they operate silently (without the clicking sound associated with traditional relays) and have a longer lifespan compared to standard relays.

Features:

• Compact design

• Easily connectable to TTL devices (microcontrollers, Arduino, etc.)

• Convenient connection with a 2-pin screw terminal   

• LED indicator (the LED indicators activate when triggered by a low-level signal)

• Operates with low-level triggering (low-level trigger)

• Can only be used with alternating current (AC)

• Power supply: 5VDC / 160mA (with all channels open)

Input Control Signal Voltage:

• 0 - 0.5V low state (SSR closed)

• 0.5 – 2.5V (unknown state)

• 2.5 – 20V high state (SSR open)

SSR Output (Per Channel): 

• Load voltage range: 75 – 264 VAC (50/60 Hz)

• Load current: 0.1 – 2 A

SSR Specifications:

• Manufacturer: OMRON

• Isolation: Fototriac

• Zero-cross: Yes

• Nominal output load: 100 – 240 VAC (50/60 Hz)

• Load Type: General purpose

Note:This relay cannot control devices operating with direct current (DC).
