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.
