EI813F Analog Input Module

Input Channels: 8 differential analog input channels.

Input Signal Types: Supports multiple standard signals, including 4-20mA DC, 0-20mA DC, 0-10V DC, etc. (configurable via software).

Resolution: 16-bit, ensuring high-precision data acquisition.

Accuracy: Typically ±0.1% of full scale (under reference conditions: 25°C ±5°C).

Isolation: Galvanic isolation between channels and between channels and the backplane, with an isolation voltage of 2500V AC (for 1 minute), effectively suppressing common-mode interference.

Sampling Rate: Up to 100 samples per second per channel (configurable).

Operating Temperature Range: -25°C to +70°C (ambient temperature).

Power Supply: Usually powered by the system backplane, with typical power consumption of ≤3W.

Mounting: Designed for DIN rail mounting, compatible with standard 35mm DIN rails.

Protection: Equipped with overvoltage protection and reverse polarity protection for input signals, enhancing module durability.

High Compatibility: Seamlessly integrates with ABB's AC500 series PLC systems, supporting standard industrial communication protocols for easy system expansion.

Flexible Configuration: Signal types and ranges can be configured via programming software (such as Automation Builder), adapting to different sensor or transmitter output requirements.

Diagnostic Functions: Provides comprehensive self-diagnostic capabilities, including open-circuit detection of current loops, overrange alarms, and module fault indicators (LED lights), facilitating quick troubleshooting.

Anti-Interference Performance: Optimized circuit design and isolation technology ensure stable operation in harsh industrial environments with strong electromagnetic interference (EMI) or radio frequency interference (RFI).

Hot-Swappable Design (optional for some models): Allows module replacement without powering off the system, reducing downtime in critical applications.

Collecting analog signals from sensors (e.g., pressure, temperature, flow, level, and weight sensors).

Acquiring data from transmitters in process control loops (e.g., 4-20mA signals from pressure transmitters or flow meters).

Monitoring and feedback of analog parameters in automated production lines to achieve precise control and regulation.

Wiring Requirements: Use shielded twisted-pair cables for signal wiring, with the shield grounded at one end to reduce interference.

Polarity Attention: For current or voltage signals with polarity, ensure correct connection of positive (+) and negative (-) terminals to avoid measurement errors or module damage.

Environmental Protection: Install in a dust-free, vibration-free, and corrosive gas-free environment; avoid direct sunlight or proximity to heat sources.

Static Protection: Wear anti-static gloves when handling the module to prevent electrostatic damage to internal components.
