模块特点

Module characteristics

Analog output: Provides 4 channels for analog output, supporting voltage and current output.

Resolution: The analog output resolution is 11 bits+symbol bits, which is 12 bits, ensuring high output accuracy.

Output range:

Voltage output range: 0.10V to 10.10V, with a minimum resolution (LSB) of 4.88mV.

Current output range: 0.20mA to 4.20mA, with a minimum resolution (LSB) of 3.91 μ A.

Compatibility: Compatible with Modicon M221, M241, M251, M262 and other series controllers, used as an expansion module.

Wiring method: There may be screw wiring or spring wiring, depending on the model (TM3AQ4 or TM3AQ4G).

Size and weight: The module has a small volume, light weight, and is easy to install in the control cabinet, suitable for situations with limited space.

Precautions for use

Output matching: Ensure that the output range of the module matches the input range of the connected actuator to avoid overvoltage or overcurrent damage to the equipment.

Wiring correctness: Correctly connect the output terminal of the module to the actuator, avoiding reverse or incorrect connections.

Power stability: Use a stable power supply to avoid power fluctuations affecting the stability of the output signal.

Load impedance: Consider the matching between load impedance and module output impedance to maintain signal integrity.

Signal isolation: When necessary, use signal isolators to reduce signal interference, especially in noisy environments.

Environmental conditions: Ensure that the module operates under the manufacturer's recommended temperature, humidity, and dust conditions.

Software configuration: Correctly configure module parameters in the controller, including output type, range, and unit, to ensure the accuracy of the output signal.

Maintenance and inspection: Regularly check the working status and wiring of the module, and perform necessary cleaning and maintenance.
