A two-channel relay module (HCMODU0115) featuring 2x Omron G3MB-202P solid state relays. This 5V 2 Channel SSR G3MB-202P Solid State Relay Module is capable of switching AC voltages between 100 and 240V at up to a 2A current. The module can be controlled from a 5V digital source such as an Arduino microcontroller.
A resistive type fuse is provided on the module to help protect excessive current draw.
This 5V 2 Channel SSR G3MB-202P Solid State Relay Module 240V 2A Output with Resistive Fuse is based on the Omron G3MB SSR relay which can control up to 2A at 240VAC. This is a 2 Channel SSR relay module, each relay channel has 3 separate terminals, NO (Normal Open), COM (Common), NC (Normal Closed).
A Solid State Relay is similar to a mechanic relay where it can be controlled through a digital signal. Solid State Relay generates no noise and has a much longer lifespan in compared to the traditional mechanic relay.
When the input logic voltage is applly to the coil, the NC will disconnect from the COM breaking the conductivity between the two. At the same time, the NO will connect with the COM allowing conductivity between them. Depending on your wiring this will turn on or off the connect load.
Input part :
- DC+: connect the power supply positive (press the relay voltage power supply)
- DC-: the cathode of a power supply
- CH1: 1 relay module signal trigger end (high-level trigger effective)
- CH2: 2 relay module signal trigger end (high-level trigger effective)
High level and low level of meaning
- High-level trigger refers to the signal trigger end (IN) had a positive voltage and the negative pole of the power supply is usually between, and the triggering end of a trigger connect with the positive pole of a power supply, when the trigger end has a positive voltage or reach the trigger voltage, the relay is attract.
- Low-level trigger refers to the signal triggering voltage between the end and the negative electrode of the power supply is OV, or trigger terminal voltage lower voltage than the positive power supply voltage, low to can trigger, make the relay, is usually the cathode of the power supply and the triggering end of a trigger mode connection, so that the relay is attract.
