The structure of the PLC control cabinet

; PLC refers to the programmable control cabinet, is usually in whole set of control cabinet, is a kind of can achieve motor, switch the control electrical cabinets, PLC control cabinet with overload, short circuit, open phase protection function, stable performance, strong anti-interference, now widely used in metallurgy, paper making, chemical industry, electric power, environmental protection, sewage treatment and other industries.

;
the structure of the PLC control cabinet:
;
1.
air switch;
a general air switch, is the power of the cabinet put oneself in another's position control. Each cabinet must have.
;

2, PLC;
select according to the need of engineering, cheng small can directly be a PLC integration, engineering is large, requires module, card type, and possibly two sets of alternate use.
;

3, power supply
a 24 VDC switching power supply, most PLC is bringing 24 VDC power supply, according to whether really need to decide whether to the switching power supply.
;
4, relay
;
general PLC to control loop can be directly to the instructions, but also may first by relay relay. Charged if PLC output is 24 VDC, but figure painting in need of control circuit of PLC for the node is 220 vac, so you must add a relay, PLC output when the instruction relay action, but the control circuit of nodes after received normally open or normally closed relay point. Choose whether to use relay according to situation.
;

5, terminal;
according to the number of signals can be configured.
;
other configuration may also increase or decrease according to actual situation.
;
the above three aspects to introduce the PLC control cabinet cabinet is the structure of the related content, by ways of cabinets can be specialized processing production PLC control cabinet, welcome to online consultation for more content.
