When it comes to wiring, the 6es7131 4bf00 0aa0 module can be a bit confusing. However, once you understand its wiring diagram, it becomes easy to design and implement a control system. This article will guide you through the process of understanding the 6es7131 4bf00 0aa0 wiring diagram.
What is 6es7131 4bf00 0aa0?
Before we dive into the wiring diagram, let’s briefly discuss what 6es7131 4bf00 0aa0 is. 6es7131 4bf00 0aa0 is a digital input module made by Siemens. It has eight inputs, each of which can be used to sense the state of an input signal. It can be used in a variety of industrial automation applications, including machinery control, process control, and building automation.
The 6es7131 4bf00 0aa0 Wiring Diagram
The 6es7131 4bf00 0aa0 wiring diagram is quite simple yet can be a bit confusing. The module has eight inputs, labeled as I0.0 to I0.7. Each input can be wired in two different ways, depending on the type of sensor being used. These two ways are:
- PNP mode: In this mode, the input is wired between the sensor and the positive supply voltage (Vcc). This mode is suitable for sensors that output a voltage when they are “on”. In PNP mode, the input is active when the sensor output voltage is high (usually the same as the supply voltage).
- NPN mode: In this mode, the input is wired between the sensor and ground (GND). This mode is suitable for sensors that output a voltage when they are “off”. In NPN mode, the input is active when the sensor output voltage is low (usually 0V or close to it).
The wiring diagram for the 6es7131 4bf00 0aa0 is shown in table 1 below:
| Input | PNP Mode | NPN Mode |
|---|---|---|
| I0.0 | X1+ | X1- |
| I0.1 | X2+ | X2- |
| I0.2 | X3+ | X3- |
| I0.3 | X4+ | X4- |
| I0.4 | X5+ | X5- |
| I0.5 | X6+ | X6- |
| I0.6 | X7+ | X7- |
| I0.7 | X8+ | X8- |
Wiring in PNP Mode
In PNP mode, the input is wired between the sensor and the positive supply voltage (Vcc) as shown in figure 1 below:
| Figure 1: PNP Wiring Diagram |
As shown in figure 1 above, the sensor output voltage (Vout) is connected to the input terminal (X) and the positive supply voltage (Vcc) is connected to the positive terminal (X+). When the sensor output voltage is high, the input becomes active and the module senses it as “on”. When the sensor output voltage is low, the input becomes inactive and the module senses it as “off”.
FAQs about PNP Wiring
Q: How do I know if my sensor works in PNP mode?
A: Check the sensor’s datasheet or manual. It should clearly state whether it works in PNP or NPN mode.
Q: Can I use PNP sensors with an NPN module?
A: No. You cannot use PNP sensors with an NPN module. The sensor and the module must be of the same type.
Q: How do I wire multiple sensors to one input?
A: You can wire multiple sensors in parallel to one input. However, make sure that the combined current draw of all the sensors does not exceed the maximum rating of the input.
Q: Can I wire the sensors in series?
A: No. You cannot wire sensors in series to one input. Each sensor must be connected to a separate input.
Wiring in NPN Mode
In NPN mode, the input is wired between the sensor and ground (GND) as shown in figure 2 below:
| Figure 2: NPN Wiring Diagram |
As shown in figure 2 above, the sensor output voltage (Vout) is connected to the input terminal (X) and the ground (GND) is connected to the negative terminal (X-). When the sensor output voltage is low, the input becomes active and the module senses it as “on”. When the sensor output voltage is high, the input becomes inactive and the module senses it as “off”.
