A module description
1, the module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A;
2, using the industry’s top -quality ultra-compact two-way isolation optocouplers, anti-interference ability , stable performance ; trigger current is only 3mA;
3, the module voltage is 5V, 12V, 24V are available ; otherwise 1,2,4,8,12 road modules to choose from ;
4 user-selectable relay control level can be high pull, pull can also be low ; module containing limiting resistor can be used directly to control the power of positive and negative , can also use the MCU I / O port control ;
5 , fault-tolerant design , even if the control line is broken , the relay will not operate ;
6 , the power indicator ( red ) , 12 relay status indicator ( blue )
7 , interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient
8 , Module size : 12.0cm * 9.0m * 2.0cm ( L * W * H )
9 with 4 fixing bolt holes for easy installation
Two module interface
Module control side: 15 line interface, the interface can be directly connected to all leads , user-friendly
1, DC +: negative external DC power supply (with 5V, 12V and 24V modules to choose from )
2, DC-: negative external DC power supply
3, VREF: optically isolated ground reference control terminal ,
If a high-level control : This signal should be connected to the negative power of the user control panel
If using low-level control : This signal should be connected to the positive supply user control panel
CH1-CH12: relay control interface,
If VREF negative one : This port high ( relative to VREF) when the corresponding relay
If VREF positive power supply : When this port is low ( relative to VREF) corresponding relay
Note : Isolated relay module is designed to adapt to the environment is bad or electromagnetic signals high demand for the occasion , if you want to achieve complete isolation , the user control panel power ( ie connection VERF reference power ) power supply and relay module (DC + / DC-) to be distinguished , if the power of the two , the effect is not completely isolated , then the user can choose a more economical in our standard relay module .
Relay outputs : 36 line interface, the interface can be directly connected to all leads , user-friendly
