  Информационные материалы

  • Analog inputs for the fail-safe SIMATIC S7 systems
  • Applicable in the ET 200M distributed I/O device with IM 153-2 HF as well as centrally with SIMATIC S7-31xF-2 DP
  • Properties of the SM 336; F-AI 6 x 0/4 - 20 mA HART:
    • 6 analog inputs with galvanic isolation between channels and backplane bus
    • Input ranges: 0 to 20 mA, 4 to 20 mA
    • Short-circuit proof power supply from 2 or 4-wire transducer via the module
    • External encoder supply possible
    • Applicable in safety mode
    • HART communication
    • Firmware update using HW Config
    • Identification data

  Область применения

  The modules are used centrally with SIMATIC S7-31xF-2 DP and in the ET 200M distributed I/O device together with SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-416F-2 and S7-400F/FH.

  0 to 20 mA and 4 to 20 mA current transmitters (also HART) can be connected as encoders.

  Дизайн

  • 6 inputs for current measurement.
  • Compact design:
    • Group fault display (SF)
    • Safety mode display (SAFE)
    • Display for channel-specific faults (Fn)
    • Display for HART status (Hn)
    • Plug options for the 20-pin front connector, protected behind the front door.
    • Labeling field on the front door.
  • Easy assembly
    Assembled like the other ET 200M I/O modules.
  • User-friendly wiring with 20-pin front connector.

  Функции

  The analog input module converts analog signals from the process to digital signals for internal processing by the fail-safe SIMATIC S7 CPUs.

  The safety functions required for fail-safe operation are integrated in the module.

  The following functions are available:

  • Resolution 15 bits + sign.
  • Measuring ranges:
    • 0 to 20 mA or
    • 4 to 20 mA or
    • 4 to 20 mA (HART)
  • Interrupt capability;
    the module sends diagnostic interrupts to the CPU of the controller.
  • Diagnostics;
    the module sends extensive diagnostic information to the CPU.
