BACHMANN SLC284 Safety Processor Module

Overview

The BACHMANN SLC284 is a high-performance safety processor designed to meet the demands of safety-critical applications. Fully compliant with the IEC 61508 standard, it can support safety systems up to SIL3. The module integrates seamlessly into M200 controllers and offers robust communication with decentralized I/O modules, providing flexibility and scalability in complex safety systems.

Technical Specifications

• Compliance:

  • IEC 61508 certified, supporting up to SIL3.

• Digital Inputs/Outputs:

  • 16 digital inputs and 8 digital outputs.
  • Outputs can be used redundantly in pairs (PL e / SIL3 / Cat 4).

• Microcontrollers:

  • Features two independent 32-bit microcontrollers for enhanced fault tolerance and performance.

• Program Cycle Time:

  • 5 ms, ensuring quick response times in safety systems.

• Communication Interfaces:

  • Supports decentralized I/O modules (SDI208, SDO204) via FASTBUS, bus expansion, CAN, or bluecom. These modules can be separated by several hundred meters for flexible system design.

• Operating Modes:

  • SAFE, PROG, TEST, and ERROR modes selectable via an operating mode switch.

• Safety Programming:

  • Safety programming via SolutionCenter software.

• Isolation:

  • Galvanic isolation between different I/O groups and from the system bus to ensure electrical safety.

• Status Indicators:

  • LED status display for each channel.
  • Operating status indicated by a display with "SAFE", "PROG", "TEST", or "ERROR" modes.

• Independent Programming Interface:

  • Programming via an independent serial interface or directly through the controller.
