Description
Relay is an electric control device, when the input (excitation) changes to meet the requirements
An appliance that causes a predetermined step change in the controlled quantity in an electrical output circuit. it
There is an interaction between the control system (also known as the input loop) and the controlled system (also known as the output loop)
The dynamic relation. Usually used in automatic control circuits, it is actually controlled by a small current
Making a large current operation of an "automatic switch" in the circuit plays an automatic regulation, safety
Protection, conversion circuit, etc.
Trigger mode: high level trigger

Maximum operating current: 12.5mA for 1 channel / 20.5mA for 2 channels
Load voltage: 5-220VDC
Load current 5A
Module life: 10 million times
Maximum switching frequency: ≤5KHz
Product weight: 1 channel 30.8g/2 channel 53.2g
Product size: 1-way 72*27*25mm/ 2-way 72*39*25mm
Positioning hole: 24.5*69.5mm for one channel / 36.5*69.5mm for two channels
Trigger voltage:
High level trigger module: 0-0.5VDC relay OFF (OFF), 1.5-32VDC
Relay on (0N)DC+ : positive supply voltage
DC- : The power supply voltage is negative
CH1: indicates the first trigger signal terminal
CH2: indicates the second trigger signal terminal
CH3: indicates the third trigger signal terminal
CH4: indicates the fourth trigger signal terminal
Note: The CH end is the module trigger end, when there is a trigger signal, solid state relay
The output switch (A and B) is closed, and the load is switched on.
Precautions for main E port R
1. Power supply and load should be used within the parameter range.
2, rated load and life is a reference value, according to different environmental factors,
The nature and type of load are quite different, so it is best in real or simulated real
Use to confirm.
3. The load capacity of the module is greatly affected by the ambient temperature and its own temperature rise
According to the actual working environment conditions, the use of air convection heat dissipation can be installed in
There is a good convection environment.
4. Electrical durability at high temperature: When the module is used at high temperature, the electrical durability will be better than that of the module
Use at room temperature is low, so please confirm in actual use.
5. Solid state relay module is divided into AC and DC. This is DC solid state relay
Can not control the AC load, only control the DC load.
6. This solid state relay uses a multimeter to measure the resistance at the output end, and the meter pen is exchanged
The resistance of one side of the measurement is large, and the other side is small, because there are diodes in the interior for protection
When a multimeter is used to measure the resistance, it is the positive resistance of the diode.
This is normal. Solid state relays, unlike electromagnetic relays, this one doesn't
The contact switch, which is designed using the switching function of electronic components, measures resistance
Not precise, equivalent to a switch in the application circuit; For all purposes
