Built-in structural features

The Siemens 6ES7288-3AM06-0AA0 consists of a bus interface controller, a digital-to-analog converter (DAC), a multiplexer and output driver stage, an optical/magnetic isolation circuit, and a terminal block. The bus interface controller is responsible for communicating with the backplane bus of the S7-1200 CPU, receiving the digital set values sent by the CPU and uploading the status and diagnostic information of the module. Then, the internal high-precision 12-bit digital-to-analog conversion chip (DAC) in the module converts the 16-bit integer data transmitted by the CPU into analog level signals. Through multiplexing technology, the output of the two channels is switched, and the subsequent operational amplifier enhances the driving capability of the signal. There is an optical/magnetic electrical isolation between the internal logic circuit of the CPU and the analog output circuit, and the terminal block is directly connected to the output driver stage.

Application scenarios:

1. Process control
Set the output speed value to the frequency converter to control the motor speed.
2. Valve control
Used for flow, pressure or level regulation, control the opening degree of the proportional servo valve.
3. Temperature control
Output the control signal to the temperature control power amplifier or heater.
4. Instrument drive
Drive external display instruments or recorders by converting the internal calculation data of Siemens 6ES7288-3AM06-0AA0 into standard analog signals.

FAQ:

Is it compatible with all S7-1200 CPUs?
The CPU itself must have an SB slot, and then it will be compatible with most standard S7-1200 CPUs.
How to diagnose when there is a fault?
The Siemens 6ES7288-3AM06-0AA0 can be diagnosed online through the TIA Portal software. The side status LED indicator lights will also indicate the running or fault status of the module. If you have any questions, you can seek technical guidance from us.
Is separate power supply required?
No. The signal board directly obtains the required power supply from the inserted S7-1200 CPU.
