5SHY35L4520 5SXE10-0181 AC10272001R0101 Control system output circuit design. According to the requirements of the production process, a variety of lights, inverter / digital DC governor start stop should be used transistor output, which is adapted to high-frequency action, and a short response time; if the PLC system output frequency of less than 6 times a minute, should be preferred to the relay output, using this method, the output circuit is simple to design, anti-interference and load carrying capacity.

5SHY35L4520 5SXE10-0181 AC10272001R0101 output with solenoid coils and other inductive loads, the load will cause surge current impact on the output of the PLC when the power is off, for this reason, DC inductive loads should be next to the diode and connected to the continuity of the diode, AC inductive loads should be connected to the surge absorber circuit, which effectively protects the PLC. When the PLC scanning frequency of 10 times / min or less. When the PLC scanning frequency is less than 10 times/min, either relay output can be used, or PLC output can be used to drive intermediate relay or solid state relay (SSR), and then drive the load.

5SHY35L4520 5SXE10-0181 AC10272001R0101 For two important outputs, it is not only interlocked inside the PLC, but it is recommended to interlock the hardware outside the PLC as well, in order to strengthen the safety and reliability of the PLC system operation. For common AC220V AC switching loads, such as AC contactors, solenoid valves, etc., they should be driven by DC24V microminiature intermediate relays, avoiding the direct drive of the PLC’s DO contacts, even though the PLC manual claims that it has the ability to drive AC220V AC switching loads.
