Use and maintenance of the output of the PLC unit Part 2
2. Diode Method.
Circuit of the use of diode circuits can be found in Figure 1, below.
For this method, we use a diode parallel to the load on the circuit. When the touch of a Three layout of the PLC input will work with current flowing through the contacts of the relay to the load. The direction of current flow in a stream running through to the positive load. (Which is a load inductance) to stop with the negative terminal of supply. The magnetic field points in the load inductance. Make the work load. In the diode-stroke does not affect anything because the timing circuits reason that the diode itself to be bias. But when the Tree Layout output to stop working. (Contact output layout of the Three separate instantaneously) in the stroke itself, this magnetic field that points in the load inductance is caused to emit energy. In the moment of birth itself will emit this energy at a voltage proportional to flow rate changes. Resulting voltage across the contacts of the Tree layout output (transient). (more…)

Use and maintenance of the output of the PLC unit Part 1
Get to know maintenance and PLC Troubleshooting. Start with the output of each unit before a prelude In this example, Omron PLC’s that many of you may be familiar with in the past or are still in use today are the same. (Nanjing tolerance of him is on) are the output of generation units CP1L.
1. Unit Contact Output.
Contact Output for the maintenance of essential. When it is time to use one of relay contacts page and then the resistance will be more The more frequently cut. The high volume flows. Lifetime of relay contacts page just so short. Thus, during the re layout output to use it regardless of load current to be output to relay to the cut with Be very careful and to consider the application output to the relay unit is used in the circuit. In the event that leads to the load inductor (coil), which in this case. Moment of contacts separated abruptly Magnetic field in the coil is reduced. This will cause a voltage proportional to flow rate changes. Own rhythm and this is the voltage across the contacts page. Which was high enough to destroy the contacts page at a glance. Pressure that occurs when the contacts page, we first separate the pressure “Transient” as the voltage during a short period at the beginning. Because of this pressure may be high enough to damage the contacts page. Therefore, if a load inductor (coil) to the more external protection circuit. With many different types depending on the voltage used in editing Horizontal resolution which can be viewed from the circuit as shown. (more…)
