24V Solid State Relay Module with Resistive Fuse

Description

1 Channel

It is an Ingenex 3-24VDC 50V solid state relay 2A, output with resistance type fuse 50V 2A. The input control signal voltage for the relay module is: (the state of the 0-2.5V low-level relay OFF; the state of the 3-24V high-level relay ON).

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 attracted.

It has the blue KF301 terminal is connected to the line of control.

2 Channel

This 24V 2 Channel SSR Solid State Relay Module 250V 2A Output with Resistive Fuse is based on the Omron G3MB -202P 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 applied 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 connected load.

Input parts :

1. DC+: connect power positive
2. DC-: connect power negative
3. CH1: relay module signal trigger point (Effective low-level trigger)
4. CH2: relay module signal trigger point (Effective low-level trigger)
   

4 Channel

This is 4 Channel 3-24V Solid State Relay Module. A solid-state relay (SSR) is just what it sounds like; an IC that acts like a mechanical relay. They allow you to control high-voltage AC loads from lower voltage DC control circuitry. They accomplish this by using infrared light as the ‘contact,’ a solid-state relay is really just an IR LED and a photo Triac sealed up into a little box. Solid-state relays have several advantages over mechanical relays.
