Switching-type position feedback
Thread Content
Position feedback with a switch, as shown in the figure. At first, that’s how I understood it: two sets of microswitches, each with normally open and normally closed contacts. The rotation of the cam by a certain angle controls the opening and closing of the switch, with a 0 or 1 signal sent back to the central control unit. But today I accidentally saw how to connect 4 wires? I’ve come specifically to ask how to connect this wiring diagram My previous idea seems to have been a bit wrong.
Terminal wiring 123456789101112 is crucial
When using 1245 in the central control system, it’s necessary to see what the central control does with those signals; one needs to examine the circuit diagrams related to interlock alarms and similar functions. Therefore, the outputs of 123456789101112 are crucial
Since the DCS has independent feedback signals for on and off states, both sets of signals need to be fed into the DCS
Four wires are connected using two microswitches, while three wires are connected to one microswitch
I think you’re right. There are 2 sets of microswitches: one for open feedback and the other for closed feedback. Each set has both normally open and normally closed configurations. When going to the control panel, you need to choose whether to use the normally open or normally closed type, and there are 2 different wiring methods for each
Two sets of signals for on and off, totaling four wires
