ABB 70EA01A-E Analog Input Module
Description
ABB 70EA01A-E (HESG 446220R1) is a high-precision analog input module for the Advant Controller 450/460 and Symphony Plus distributed control systems, designed to acquire and condition process signals from field transmitters.
Features
Supports multiple signal types with channel-level isolation, provides high noise immunity, and integrates seamlessly into ABB’s redundant I/O architecture for critical process control.
Technical Specifications
Input Channels
- Number of channels: 8
- Supported input types: 0–20 mA, 4–20 mA, 0–5 V, 1–5 V (software-configurable per channel)
- Input impedance: ≤250 Ω for current inputs; ≥100 kΩ for voltage inputs
Accuracy & Performance
- Overall accuracy: ±0.1% of full scale
- Resolution: 16 bits
- Common-mode rejection ratio: >60 dB
- Isolation: channel-to-channel and channel-to-bus (≥500 V AC)
Environmental & Mechanical
- Operating temperature: 0 °C to +60 °C
- Storage temperature: –25 °C to +70 °C
- Humidity: 5% to 95%, non-condensing
- Module dimensions: approx. 35 mm × 180 mm × 120 mm
- Mounting: plug-in to ABB I/O baseplate in Symphony rack
