Description
Product Overview
The ABB IMSED01 is a dedicated Emergency Shutdown (ESD) safety module designed for ABB’s Bailey Infi 90 DCS and Symphony Plus platforms. It serves as the core component of safety-critical systems, providing fail-safe emergency shutdown capabilities in industrial environments. The module adheres to IEC 61508 and SIL 3 safety integrity standards, ensuring rapid response to hazardous conditions (e.g., fire, overpressure, equipment failure) by executing pre-programmed shutdown sequences.
The IMSED01 integrates dual-channel redundancy (2oo3D architecture) and self-diagnostic functions to minimize false trips and undetected failures. It interfaces with field devices (emergency pushbuttons, flame detectors, pressure switches) via intrinsically safe (IS) I/O channels and communicates with the control system via InfiNet or Modbus protocols. Its hot-swappable design allows maintenance without disrupting safety loops, while the enclosure with IP20 protection ensures durability in harsh industrial settings.

Main Features and Advantages
Safety-Critical Design:
The IMSED01 prioritizes safety with fault tolerance (e.g., single-point failure immunity) and diagnostic coverage >99% for critical circuits. Its hardwired emergency shutdown paths bypass software logic during catastrophic failures, ensuring deterministic response within <10 ms. The module supports voting logic (1oo2, 2oo3) for input signals to reduce nuisance trips in redundant sensor configurations.

Intrinsically Safe Interfaces:
All I/O channels comply with IEC 60079-11 intrinsic safety standards, allowing direct connection to field devices in hazardous areas (Zone 1/21). The module’s galvanic isolation (2500 Vrms) prevents ground loops and protects against transient surges, while channel-by-channel fusing safeguards against short circuits.

Flexible Programming:
Using ABB’s Safety Builder M software (based on IEC 61131-3), users can configure shutdown logic, timer functions, and alarm priorities. The module supports ladder diagram (LD), function block diagram (FBD), and structured text (ST) programming languages, with built-in libraries for standard safety functions (e.g., emergency stop, process trip, manual reset).

Real-Time Monitoring:
Front-panel LED indicators display channel status, system health, and alarm conditions. The module integrates the IMRIO02 remote I/O slave for extended I/O capacity and communicates with the IMMFP12 processor for central data logging. Its SNMP interface enables remote monitoring via SCADA systems, while non-volatile memory preserves configuration during power outages.
