ABB 81EA04C-E GJR2393400R1210 Analog Input Module

  • Product Type & Core Role: It is a mixed analog input/output module of ABB’s AC500 series, a key component for industrial automation process control. Integrating both analog signal acquisition and control command output functions, it converts continuous analog signals from on-site sensors into digital signals, while transforming control signals processed by PLCs into analog outputs, enabling a closed-loop "acquisition-calculation-control" process.
  • Key Specifications: Compatible with AC500 series PLC hosts. It includes 4 analog input channels and 2 analog output channels. Inputs are compatible with 4-20mA/0-10V signals, and outputs support 4-20mA DC current signals. The measurement accuracy is ±0.1% of full scale, and the output accuracy is ±0.2% of full scale. The operating temperature range is -25℃~+60℃, with a protection class of IP20. Its power consumption is ≤3W, featuring a modular design compatible with standard AC500 series module sizes for easy rack integration.
  • Core Functional Features: Both input and output channels are equipped with photoelectric isolation, offering strong anti-electromagnetic interference capability to ensure accurate signal transmission. It supports online software calibration, allowing deviation correction without disassembly. Equipped with LED status indicators, it displays module power supply, communication, and channel working status in real time, facilitating quick fault localization.
  • Typical Application Scenarios: Widely used in process control systems of chemical, power, and metallurgical industries—such as reactor pressure regulation, production line flow control, and temperature closed-loop adjustment. It helps achieve precise control of industrial process parameters, enhancing production stability and product quality consistency.
