More Information

Overview Manuals Applications Performance & Efficiency Diagnostics Installation & Integration

Features:

  • Combines four flexible measurement channels with two programmable analog command outputs.
  • Offers selectable conversion cycles for fast acquisition or improved interference rejection.
  • Supports diagnostic and hardware interrupts for time-sensitive analog processing.
This ordering configuration is the IF 961-AIO mixed analog interface identified by code 01H.

It connects low-level process measurements and analog references directly to the M7 automation program.

The saved channel type, measuring range and shield termination are essential because voltage and current wiring are not interchangeable.

Apter Power can review sourcing, documentation and system matching for 6ES7961-2AA00-0AC0.
Verified resources for Siemens 6ES7961-2AA00-0AC0: Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Test benches can acquire four transducer values while generating two analog setpoints from the same submodule.
  • Process skids use the universal inputs for transmitter, voltage or resistance measurements selected by software.
  • Motion or drive supervision can combine analog feedback with command references inside an M7 real-time application.
  • The input converter uses 16-bit bipolar representation for signed process values.
  • Selectable cycle times range from fast sub-millisecond acquisition to a 185 ms high-rejection mode.
  • Published operating error for voltage and current ranges is within ±0.8 percent under stated conditions.
  • Diagnostic interrupts report channel or parameter conditions to the automation program.
  • Voltage and current inputs have separate destruction limits that must not be exceeded during commissioning.
  • Short-circuit current on a voltage output is limited to approximately 40 mA.
  • All analog wiring is routed through the specified 25-pin D-sub connector.
  • Shielded signal cable is required, with a documented maximum route of 200 m.
  • The external 24 V load supply must be present with correct polarity before the output section is used.
Description
6ES7961-2AA00-0AC0 digitizes four bipolar analog channels with 16-bit representation and supplies two 12-bit bipolar output channels. The input section supports voltage, current, two-wire or four-wire transmitter and resistance configurations.

Multiple conversion-cycle choices allow the application to trade measurement speed against noise rejection. Hardware and diagnostic interrupt functions can notify the automation program without waiting for a routine software scan.

Channel range, wiring method, conversion time and common-mode conditions must be copied from the M7 project before replacement. Only shielded analog cabling should be used, with the documented separation from disturbing conductors.
