HIMA F8650E (F 8650E) Central Module

Product Overview

The HIMA F8650E Central Module is a key component for safety-related systems used in PES (Process Automation Systems), such as H51q-MS, HS, and HRS. It is designed to meet safety requirements for SIL 1 to SIL 3 and AK 1 to AK 6, making it suitable for applications where safety is a critical concern.

Technical Specifications

• Type: F8650E Central Module
• Use: For safety-related systems in PES H51q-MS, HS, HRS
• Safety-Related Requirements: SIL 1 – 3, AK 1 – 6

Processor and Memory

• Microprocessor:
  • Intel 386EX, 32-bit
  • Clock Frequency: 25 MHz
  • Memory per Microprocessor:
    • Flash-EPROM: 1 MB
    • SRAM: 1 MB (Efficiency dependent on the operating system version)
• Operating System: Custom operating system supporting user programs and data handling

Interfaces and Diagnostics

• Serial Interfaces:
  • Two RS-485 interfaces with galvanic insulation.
• Diagnostic Display:
  • Four-digit matrix display for error and system diagnostics.
  • Two LEDs for error indication (CPU and I/O).
  • Toggle switches and push-button for detailed error information and error reset (ACK function).
• Shutdown on Fault: Safety-related watchdog with a 24 VDC output, up to 500 mA current drain, and short-circuit protection.

Physical Characteristics

• Construction:
  • Two European standard PCBs: one for the central module and one for the diagnostic display.
  • Space Requirements: 8 TE
  • Operating Voltage: 5 V, 2 A
• Cooling: If upgrading from an F8650 to the F8650E, modification to the cooling fan concept is required.

Pin Allocation for RS-485 Interface

• Pin 1: Not used
• Pin 2: RP (5V, decoupled by diodes)
• Pin 3: A/A’ (RxD/TxD-A, Receive/Transmit Data A)
• Pin 4: CNTR-A (Control signal A)
• Pin 5: C/C’ (DGND, Data Ground)
• Pin 6: VP (5V, positive pole of power supply)
• Pin 7: Not used
• Pin 8: B/B’ (RxD/TxD-B, Receive/Transmit Data B)
• Pin 9: CNTR-B (Control signal B)
• Switch Settings:
  • S1-8: Transmission rate (9600 bps when ON, 57600 bps when OFF)
  • S1-1/2/3/4/5: Set the bus station number

Additional Features

• Backup Battery:
  • Lifetime of backup battery with mains power off: 100 days at 60°C
  • Recommended battery replacement every 2 years (e.g., CR 2477N, HIMA part no. 44 0000018).
• Event Handling:
  • Up to 2048 events can be defined
  • 500 events can be stored in the event buffer

Notes for Start-up and Maintenance

• Check the bus station number and transmission rate at switch S1 for correct settings.
• Battery: Lifetime of the backup battery is about 100 days when the main power is off at 60°C.
