ABB EI 803F Ethernet Module 10BaseT (Twisted pair)

Key Features and Purpose

8 Digital Input Channels for Safety Applications
Provides eight dedicated channels for connecting safety-rated digital inputs.

Certified for Functional Safety
The EI803F is certified for use in Safety Instrumented Systems (SIS), typically up to SIL3 (Safety Integrity Level 3) in accordance with IEC 61508 and IEC 61511, and often to Performance Level e (PL e) according to ISO 13849-1. This certification makes it suitable for applications where failure could result in significant hazards.

24 V DC Inputs (Current Sinking/Sourcing)
Supports both sinking and sourcing input configurations, allowing flexible integration with a variety of field devices.

Advanced Diagnostics
Equipped with comprehensive self-diagnostic features to detect internal faults and field wiring issues such as short circuits and open circuits. These diagnostics maintain the integrity of the safety loop and provide error signals to the safety controller (e.g., ABB AC 800M HI).

Dedicated Process Voltage Supervision
Monitors the 24V process voltage to ensure reliable operation and enhance diagnostic coverage.

Non-Redundant Module
Although designed for safety applications, the EI803F itself is a non-redundant module. System-level redundancy is typically achieved by using multiple EI803F units with 1oo2 or 2oo3 voting logic in the safety controller.

Input Filters
Offers configurable input filters to minimize electrical noise and prevent false triggering from noisy signals.

LED Indicators
Equipped with LEDs to indicate module status, faults, and individual channel states—simplifying local diagnostics and maintenance.
