Serial module FI 820F

• FI 820F3BDH000031R1
• Fieldbus Module, Serial (2 channel)
  To use together with PM 802F or PM 803F.

The FI 820F module provides connectivity to a variety of serial fieldbuses and serial protocols. Standard protocol is MODBUS By using different connection cables the physical nterface can easily be selected: RS485 (half duplex), RS422 (full duplex) or RS232. All interfaces are electrically isolated and support redundant operation in conjunction with a second AC 800F.

Features:
• Provides 2 serial interfaces
• Transmission rates up to 38.4 kBd configurable
• Physical interfaces RS485, RS422, RS232 selectable
• Electrical isolation
• Module can be removed or inserted during operation
• Redundant operation, with redundant AC 800F
• G3 compliant Z variant available
