Description

GE  IC693ALG220  analog input module

Function and application: It is mainly used to convert external analog input signals into digital signals for processing and control by PLC. It can receive ±10V DC voltage input signals and is suitable for connecting various sensors or transmitters whose output is voltage signals, such as pressure sensors, temperature sensors (converted to voltage signals through transmitters), etc. In industrial automation control systems, it is used to collect process variables of analog quantities. Provide data input for the PLC to monitor and control physical quantities such as temperature, pressure and flow rate.

Hardware specifications:
Number of input channels: It has 4 input channels and can simultaneously collect 4 analog input signals.
Resolution: The resolution of the converted digital signal is 12 bits, which can provide high accuracy to represent analog signals. The resolution of the corresponding voltage signal is 5mV/20μA (1LSB = 5mV).
Update rate: The update rate of each channel is 4ms, meaning that the input signal can be sampled and converted once every 4ms, enabling timely tracking of changes in the analog signal.

Isolation feature: There is an isolation voltage of 1500V between the field side and the logic side, which can effectively prevent external electrical interference from entering the PLC system and improve the stability and reliability of the system.
Input impedance: The input impedance is greater than 9 megohms in voltage mode and 250 ohms in current mode.
Accuracy: The typical absolute accuracy is ±10mV/40μA, and the maximum absolute accuracy throughout the entire operating temperature range is ±30mV/160μA.

Linearity: Better than one least significant bit.
Cross-channel rejection ratio: greater than 80dB means that the mutual interference between each input channel is relatively small.
Input filter response: 17Hz, which can filter the input signal to a certain extent and reduce the influence of high-frequency noise.
