Siemens PLC transistor CPU224 comes with analog output?

The CPU224XP can be connected to 2 0-10V analog (A+ and M, B+ and M respectively) in two wires, and your output is 4 20mA, which needs to be converted into 2-10V with a 500 ohm precision resistor in parallel. The specific wiring is: 1, terminal M:

Connect the negative power cord of the three-wire sensor and one end of the precision resistor; 2. Terminal A+ (or B+): connect the signal line of the three-wire sensor and the other end of the precision resistor; 3. The positive power cord of the three-wire sensor is connected to the 24VDC positive terminal L+.

A+ and B+ are two analog inputs corresponding to M, which can input a voltage signal of 0 5 and 0 10V, and you can rent M i V is an output signal, which can only be connected to one of the outputs, I is the current output, and V is the voltage output.

Therefore, the CPU224XP has 2 analog inputs and 1 analog output contact.

di do is a digital quantity, and ai ao is an analog quantity (depending on how you understand the switching quantity and the digital quantity).

The manual says digital, probably because the input and output must be active, although the power supply is external. Personally, it is understood as a switching quantity. Technical Specifications CPU 224 CPU 224 XP

Integrated digital inputs and outputs: 14 in, 10 out, 14 in, 10 out.

Integrated analog inputs: 0 inputs, 0 outputs, 2 inputs, 1 outputs.

Number of expansion modules that can be connected (max) 7 7 7.

1. Switch: on-off signal, passive signal, resistance test method for resistance 0 or infinity;

It can also be an active signal, the professional name is a step signal, that is, 0 or 1, which can be understood as a pulse quantity, and multiple switching quantities can be composed of digital quantities.

2. Digital: There are signal types composed of 0 and 1, which are usually regular signals after encoding. The relationship with the analog quantity is the quantized analog quantity.

A digital quantity is defined as a discrete signal that changes intermittently in time and value.

The switching quantity is passive, that is, it needs the output power supply of the device to detect it (this is also the amount of the device, for example, the non-power input of the comprehensive protection device is an externally provided amount of input); It can also be encoded with 0 and 1 to make various communication codes.

The 224 input and output are all switches, and the 224XP host comes with analog input and output.

Switching quantities, although analogue quantities can be handled by extending the analogue module.

If you don't need your frequency conversion stepless speed change, you don't need an analog module, you can use it directly with the switch, we generally use the switch, as you can see in the figure below

There is no difference, they are all analog inputs, which are equivalent to No. 1 and No. 2.

All 0-10VDC share a m 0-32000 range, corresponding to AIW0 and AIW2
