Analog output module TM3AQ4
TM3AQ4 is an analog output module in the Modicon TM3 series from Schneider Electric. It is mainly used in industrial automation control system to provide analog signal output to the actuator. It has 4 analog output channels to support voltage and current output. Its analog output resolution is 11 bits + symbol bits, that is, 12 bits, ensuring a high output accuracy.
The voltage output ranges from 0.10V to 10.10V and the current output ranges from 0.20mA to 4.20mA, with a small minimum resolution. In addition, the module is compatible with the Modicon M221, M241, M251, M262 series of controllers and can be used as an expansion module.
In practical applications, it is necessary to ensure that the output range of the module matches the input range of the connected actuator to avoid over-voltage or over-current damage to the device. At the same time, attention should be paid to correctly connecting the output end of the module and the actuator to avoid reverse connection or wrong connection. Use a stable power supply to avoid power fluctuations affecting the stability of the output signal. When necessary, use a signal isolator to reduce signal interference, especially in noisy environments. In addition, it should be noted that the module operates under the manufacturer’s recommended temperature, humidity and dust conditions.
