Product Description

The Analog Output module acts as a Digital-to-Analog Converter ($\text{DAC}$). It receives a numerical value (a digital code, typically a $16\text{-bit}$ integer) from the $\text{PLC}$‘s central processing unit and converts it into a scaled current or voltage signal. This signal is then transmitted to an analog actuator, such as a proportional valve, a damper control, or a variable speed drive ($\text{VSD}$), allowing for fine, incremental adjustment of a physical process variable (e.g., speed, flow, position).

Siemens offers a range of $\text{AQ}$ modules, often featuring universal channels that can be individually configured for either voltage or current output.

Product Parameters

Product Advantages

1. High Precision and Repeatability: With high-resolution $\text{DACs}$ ($\text{up}$ to $16\text{bits}$) and low basic error limits, Siemens $\text{AQ}$ modules provide highly accurate and repeatable control of final control elements.
2. Universal Channel Flexibility: Modern modules often feature universal outputs, allowing each channel to be individually parameterized for different current or voltage ranges, simplifying stock-keeping and project planning.
3. Advanced Channel Diagnostics: Integrated diagnostic functions detect critical issues like wire break (for current outputs) and $\text{short}$ $\text{circuit}$ (for voltage outputs). These faults are reported directly to the $\text{PLC}$ and engineering system ($\text{TIA}$ Portal), enabling swift troubleshooting and minimizing process downtime.
4. Integrated Engineering: Full integration into the $\text{TIA}$ Portal allows for simple scaling, parameterization, and simulation of the analog outputs without complex programming.
5. Robustness and Design: Designed for continuous operation in harsh industrial environments, offering reliable performance under wide temperature ranges and high $\text{EMC}$ tolerance.

Important Notes (Precautions)

• Cable Shielding and Grounding: Always use shielded, twisted-pair cables for analog signals and ensure the shield is properly connected to the functional earth/ground at the module side to prevent electromagnetic interference and maintain signal integrity.
• Output Range Configuration: The chosen output range ($\text{e.g.},0\text{–}20\text{mA}$ vs. $4\text{–}20\text{mA}$) in the hardware configuration must precisely match the range expected by the connected actuator/field device. A mismatch can lead to incorrect control.
• Actuator Load Compliance: Verify that the total load resistance (including cable resistance) for current outputs does not exceed the module’s maximum permissible load impedance, or the output current will be distorted ($\text{clamped}$).
• Behavior on Fault/Stop: Critically assess and configure the module’s behavior ($\text{Hold}$ $\text{Last}$ $\text{Value}$ or $\text{Substitute}$ $\text{Value}$) for $\text{CPU}$ $\text{STOP}$ or module failure. An incorrect setting could result in uncontrolled actuator movement and safety issues.

Product Applications

• Motion and Drive Control: Providing the speed setpoint signal ($\text{e.g.},0\text{–}10\text{V}$) to Variable Speed Drives ($\text{VSDs}$) for motor control in pump, fan, and conveyor applications.
• Process Flow and Level Control: Sending the control signal ($\text{e.g.},4\text{–}20\text{mA}$) to current-to-pressure ($\text{I/P}$) converters or direct-actuating proportional valves to regulate fluid flow or level in tanks.
• Heating, Ventilation, and Air Conditioning ($\text{HVAC}$): Controlling proportional damper actuators, mixing valves, and heating elements to maintain precise environmental conditions.
• Industrial Furnaces and Ovens: Supplying the setpoint for power controllers ($\text{SCRs}$) to regulate heat output with high precision.
• Robotics and Positioning: Providing fine control signals to servo or hydraulic systems for continuous positioning tasks.
