Binary Output with Line Fault Transparency - Series 9175

Binary Output with Line Fault Transparency - Series 9175

Basic function: binary output, 1 channel.

The binary output is used for the intrinsically safe operation of Ex i solenoid valves or indicators.

The version 9175/10-1.-12 LFT is characterised by line fault transparency. This function makes it possible to signal cable faults directly to the control level via the signal channel. The input for the binary output is high impedance in case of fault.

  • Intrinsically safe output [Ex ia] IIC
  • Galvanic isolation between input and output
  • Open-circuit and short-circuit monitoring (can be switched off)
  • Line fault transparency (LFT): line fault signalling directly via output on PLC / DCS
  • For use up to SIL 2 (IEC 61508)
