Information

Overview Downloads Applications / Compatibility Product Precautions
  • Siemens 6ES7331-7KF02-0AB0. A mixed-signal S7-300 station can use one SM 331 for several sensor technologies, provided the channel-group settings match the wiring.
Product type: SM 331 analog input
System: SIMATIC S7-300
Analog inputs: 8; 4 for resistance measurement
Input types: Voltage, current, thermocouple, RTD and resistance
Eight analog inputs support voltage, current, thermocouple, RTD and resistance measurements; resistance measurement uses four inputs. Supported current ranges include 0-20 mA and 4-20 mA. Thermocouple types E, J, K, L and N and standard Pt100/Ni100 RTDs are supported.

Integration times of 2.5, 16.67, 20 and 100 ms correspond to basic conversion times of 3, 17, 22 and 102 ms. Resolution and interference suppression depend on the selected integration and measurement mode. Preserve the configured range and engineering scaling when replacing the module.

The 20-pin front connector carries the field connections. Inputs are isolated from the backplane and electronics supply, but are not isolated from each other. Diagnostics and limit alarms are parameterizable, and the red SF LED gives a group-error indication. Use the diagnostic record to identify the affected circuit.

The technical reference preserves Siemens technical pages. The installation guide is prepared by Apter Power for planning and verification. Apply the complete Siemens and machine procedures during work.
Apply the approved SIMATIC S7-300 maintenance procedure and verify the following model-specific conditions before release.
Preserve channel allocation

It provides eight analog inputs; four are available for resistance measurement.

Select the thermocouple type

Types E, J, K, L and N are supported. Match the configured sensor and compensation method to the wiring.

Match current-loop settings

Supported current ranges include 4-20 mA and 0-20 mA, with 25 ohm input resistance for these ranges.

Check isolation boundaries

The channels are isolated from the backplane and electronics supply, but not from each other.

Retain integration settings

Selectable integration times are 2.5, 16.67, 20 and 100 ms; basic conversion times are 3, 17, 22 and 102 ms. Resolution and interference suppression depend on the selected mode.

Verify the front connector

A 20-pin front connector is required. Preserve the channel wiring and verify the measurement settings before reconnecting the sensor circuits.
