Solid State Module with 2 Relays (250 V, 2 A)

Technical specifications

• Operating voltage: up to 240 V AC (50 - 60 Hz)
• Current: up to 2 A
• Control voltage: 5 V
• Current consumed: 160 mA
• Safety with 2 A resistance
• 2 independent channels

This product is a module with 2 solid state relays useful for medium power AC applications. Relays resist to 240 V, alternating current at a frequency of 50 Hz - 60 Hz. The maximum current of each channel is 2 A.

State solid state relays have much smaller dimensions than normal ones with coil control. Their names are related to how they work, that they have no moving parts.

Instructions for use

1. Connect the consumers to the mode.

It is advisable that a single consumer is connected to each channel in order not to request it.

2. Power up the module with a voltage of 5 V.

The module is powered by pins marked  DC +  and  DC-. 

WARNING! Observe the polarity, otherwise you may damage the module.

3. Connect the module to a development board.

To control this module, you need to have a development board with at least 2 digital pins (to control the 2 individual relays).

Control pins are marked with  CH1  and  CH2. If you have a consumer that consumes enough current, only a pulse with the logic voltage 1 is required to switch the relay on / off. If the consumer consumes too little current, the relay will not turn on and the logic voltage 1 should be maintained on the relay pin.
