FLM-420-O8I2-S Octo-output interface module, 2-input

Commercial Type No.: FLM-420-O8I2-S
Product No.: F.01U.033.255

FLM-420-O8I2-S Octo-output interface module, 2-input
  • Eight individually switchable semi-conductor outputs
  • Outputs are electrically isolated from LSN loop and short-circuit proof
  • Max. switchable current per output 700 mA
  • Individually selectable monitoring functions (EOL or contact) for the two inputs each
  • Maintains LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators
  • Easy wiring thanks to pluggable terminal blocks
