NM-2NRJ4 Relay Module

NM-Series
Relay modules are mainly small electromagnetic relays, supplemented with power relays, terminal-type module interface devices with instruction and protection function. Input protection; output over-voltage protection; output over-current protection. It is widely used in the interface between peripheral devices, control signals and adjustment device of automation process to achieve matching of frequency and power.
Graphic symbols of electromagnetic relay
Coil and contact symbols are shown in the figure below:

1. The series of relay products include DC coil and AC coil. Contacts include 1-pole NO, NC, transfer;
2. Note them when ordering if you need over-voltage protection, slow flow protection, over-current protection (over-voltage and over-current protection can be chosen at the same time; 2-pole or over 2-pole of relay contacts can only add slow flow protection);
3. Conventional products have AC and DC input, voltage range: 24VAC/DC;
4. Customed voltage range: 3-48VDC, 110VAC, 220VAC(380VAC in R & D);
5. Relay module with over 16 groups can be customized;
6. Wiring diagram of relay module: an example of 24VDC/A.

VV for common input terminal, A, B for the control terminal;
When: VV input 24VDC positive, A and B for 24VDC negative;
When: VV input 24VDC negative, A and B for 24 VDC positive;
24VAC input same as 24VDC;
Input A and B control relays A and B respectively;
Input method of 4 groups, 8 groups, 16 groups are all the same, please refer to this.
