Description
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:
The series of relay
products
include DC coil and AC coil. Contacts include 1-pole NO, NC, transfer;
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);
Conventional
products
Relay module with over 16 groups can be customized;
