  • Analog inputs for fail-safe SIPLUS S7 systems
  • Applicable in the ET 200M distributed I/O device with IM 153-2 HF as well as centrally with SIPLUS 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 mA to 20 mA, 4 mA to 20 mA
    • Short-circuit proof power supply of 2 or 4-wire transmitter via the module
    • External encoder supply possible
    • Applicable in safety mode
    • HART communication
    • Firmware update using HW Config
    • Identification data
    • Temperature range -25 … +70 °C;
      (+70 °C when ensuring a forced convection with a minimal air velocity of 0.3 m/s through the module. If a violation of the permissible, specified parameters is detected during maintenance or by automatic diagnostics, the modules must be proof-tested by the manufacturer. Without this measure the temperature range is -25…60°C)

SIPLUS ET 200M SM336 F 6AI 15BIT -25 … +60 DEG C 70 DEG C WITH FORCED CONVECTION WITH CONFORMAL COATING BASED ON 6ES7336-4GE00-0AB0 . FAILSAFE ANALOG INPUTS FOR SIMATIC SAFETY, WITH HART SUPPORT, UP TO CATEGORY 4 (EN954-1)/ SIL3 (IEC61508)/ PLE (ISO13849), 1 X 20 PIN
Design

  • 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.
Function

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.
Application

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.
