SD812F 3BDH000014R1 Embedded External Output Circuit Board

SD812F 3BDH000014R1 all have LED indicators can help to check whether the fault is caused by external devices. Whether in the simulation debugging or practical applications, if the system can not be a circuit in accordance with the requirements of the action, you should first check whether the PLC input switch contact point is reliable (generally through the input LED indicator or direct measurement of the input), if the input signal failed to transfer to the PLC, you should go to check the input corresponding to the external circuit; if the input signal has been captured, and then look at the PLC whether the corresponding output instructions If the input signal has been captured, then see whether the PLC has corresponding output indication, if not, then it is the problem of internal procedure or the problem of output LED indicator; if the output signal has been sent out surely, then you should check the external output circuit.

The SD812F 3BDH000014R1 has LEDs to help check whether the fault is caused by an external device. Whether in the simulation debugging or practical applications, if a system circuit can not act in accordance with the requirements, you should first check whether the PLC input switch electrical contact point is reliable (generally by viewing the input LED indicator or direct measurement of the input), if the input signal fails to transfer to the PLC, you should go to check the input corresponding to the external circuit;

SD812F 3BDH000014R1 The entire PLC internal programme, external output points and wiring increase little, and the performance price is relatively high. If the input signal has been captured, then look at the PLC to see if there is a corresponding output indication, if not, it is the problem of the internal procedure or the output LED indicator; if the output signal has been convinced to send out, then you should go to check the external output circuit (from the PLC output backward to check).
