Overview Manuals Applications Compatibility Integration Standards

Features:

  • Bundles an eight-channel isolated SM 331 analog input module.
  • Includes the 20-pole screw front connector for field termination.
  • Supports voltage, current, thermocouple and resistance measurements.
The current ordering configuration is 6ES7331-7KF02-4AB1, the SM 331 Analog Input Module Bundle documented for SIMATIC S7-300.

In the intended system role, the module accepts voltage, current, thermocouple and resistance signals with selectable 9-, 12- or 14-bit resolution. It provides diagnostics and process-alarm capability.

For selection and commissioning, match measuring type, range module settings, channel wiring, compensation method and S7-300 hardware configuration before installation. The product has been in phase-out since 1 October 2023.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Acquires eight analog process signals in an S7-300 automation station, for its documented operating duty.
  • Measures thermocouple or resistance inputs for machine temperature monitoring, through the intended receiving-system interface.
  • Provides diagnostic analog acquisition for retrofit and service of installed PLC racks, in the configured and commissioned installation.
  • The package is intended for SIMATIC S7-300 central or distributed configurations supporting this SM 331, for the documented host or measurement platform.
  • Its 20-pole screw connector is the specified field-termination component in the bundle, before an existing connection or channel is reused.
  • Hardware configuration must recognize the module order number and supported firmware behavior, so the configured interface remains compatible in service.
  • Measuring-range modules and field wiring are set for each channel group before startup, so the installed interface matches the documented arrangement.
  • The front connector can be removed for maintenance after conductors are secured and labelled, without changing the defined hardware or signal path.
  • Active-backplane handling is allowed only where the installed station supports that function, before the channel or assembly is accepted for service.
  • Siemens lists RoHS compliance from 1 March 2012, as recorded for the supplied package.
  • The Industry Mall record gives export classifications AL N and ECCN N, within the documented export classification.
  • The stated commodity code is 85389091 for this packaged product, in the official product commodity record.
