General Description

The device transfers the transmitter current to two separate isolated output circuits driving loads up to a certain limit. It can be used to activate an alarm when the input cable is broken, as no current flows into terminal 8, triggering the Line Fault Detection (LFD) output to turn on.



  • Number of Input Channels: Not specified (implies multiple inputs)
  • Input Current Range: 0-20mA


  • Number of Output Channels: Not specified (implies multiple outputs)
  • Output Isolation: Isolated between input, output 1, output 2, and power supply

Power Requirements

  • Power Supply Voltage Range: 20-35V DC
  • Power Consumption:
    • At 20V DC with a 20mA signal: Maximum 220mA
    • At 35V DC with a 0mA signal: Maximum 110mA
    • At 20V DC with a 20mA signal: Maximum 1220mA (likely a typo, should verify actual max)
    • At 35V DC with a 20mA signal: Maximum 90mA


  • Voltage Drop Across Input Terminals (8 & 9): Not specified
  • Load Resistance: 1.2Ω
  • Transfer Accuracy at 25°C: Better than 20µA for both outputs
  • Line Fault Detection (LFD) Output: Transistor open collector output

Additional Information

  • Input Isolation: Ensures no electrical connection between the input and outputs, providing safety and signal integrity.
  • Material: Likely durable and suited for industrial environments (specific material not mentioned but commonly would be industrial-grade materials).
