Description
Siemens 6ES7331-1KF02-0AB0 is a SIMATIC S7-300 analog input module (SM 331 AI 8 x 13 Bit) providing 8 analog input channels for voltage, current, resistance, and temperature measurement. The module features 13-bit resolution (12 bits + sign) with integrating conversion method and configurable interference frequency suppression at 50 Hz or 60 Hz.
The module supports multiple measurement types including ±5 V, ±10 V, 0–10 V, and 1–5 V voltage ranges; ±20 mA, 0–20 mA, and 4–20 mA current ranges; 600 Ω and 6 kΩ resistance ranges; and temperature measurement via Pt100, Pt200, Pt500, Pt1000, Ni100, Ni1000, KTY83/110, and KTY84/130 RTD sensors. Input configuration is software-selectable per channel.
The 6ES7331-1KF02-0AB0 draws 90 mA from the backplane bus and 25 mA per channel from the 24 V DC sensor supply (L+), with total power loss of 1.3 W. Each sensor supply output is short-circuit protected. Basic conversion time is 52 ms per channel, resulting in a channel scan time of 416 ms for all 8 channels. Integration time is 16.7 ms for 50 Hz or 20 ms for 60 Hz interference suppression.

The Siemens SIMATIC S7-300 Analog Input Module (6ES7331-1KF02-0AB0) is an 8-channel, 13-bit resolution module used for voltage, current, resistance, and temperature measurement. Key considerations include using hardware update HSP2067 in STEP 7 V5.4+ for configuration, handling unused channels by setting them to "disabled," and observing the 40mA current input destruction limit.
The 6ES7331-1KF02-0AB0 Siemens Analog Input Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

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.
The Siemens 6ES7331-1KF02-0AB0 is a SIMATIC S7-300 analog input module (SM 331) featuring 8 isolated inputs with 13-bit resolution. It supports voltage, current, resistance, and temperature measurements (Pt100, Ni100, PTC/KTY) with a 66 ms conversion time. The module requires a 40-pole front connector and supports 2/3/4-wire connection methods.
- HVAC & Building Management Systems:Monitors duct temp, humidity, and damper positions via mixed signals.
- Food & Beverage Processing Equipment:Tracks critical process temps with Pt100/Ni100 RTD sensors.
- Water & Utility Treatment Plants:Pressure, flow, and level monitoring with 4-20mA transmitters.
- Automated Assembly Lines:Load cells for weighing & displacement sensors for precision inspection.
- Motor Control Centers (MCC):Monitors winding temps with PTC or KTY silicon sensors.
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Channel Count: Ensure the replacement provides at least 8 channels.
Isolation: The -1KF02 is isolated (500V DC); ensure your replacement offers similar protection to avoid ground loop interference.
Front Connector: The -1KF02 uses a 40-pin connector. Some smaller S7-300 modules use 20-pin connectors, which would require rewiring.
Resolution: 13 bits (original) vs. 12 or 16 bits (alternatives). Higher resolution is generally backward-compatible but may require software scaling adjustments.
Technical notes
The module provides diagnostics for wire break, underflow, and overflow conditions, with programmable diagnostics interrupt, hardware interrupt, and limit interrupt capabilities. Group error is indicated by a red SF LED. Isolation is provided between channels and backplane and between channels and L+ at 500 V DC; there is no isolation between individual channels.
