SIEMENS 6ES7331-1KF01-0AB0 SIMATIC S7-300, ANALOG INPUT SM 331 :

SIMATIC S7-300, ANALOG INPUT SM 331, OPTICALLY ISOLATED, 8 AI, 13 BIT RESOLUTION, U/I/RESISTANCE/PT100, NI100, NI1000, LG-NI1000, 66 MS MODULE UPDATE, 1 X 40 PIN.

The 6ES7331-1KF01-0AB0 is an SM 331 analog input module from Siemens' SIMATIC S7-300 series, designed for precise conversion of analog signals into digital data for industrial automation. This module features 8 isolated analog input channels with 13-bit resolution, supporting both voltage (0–10 V) and current (4–20 mA) signals. It integrates channel-to-channel and channel-to-backplane isolation to ensure signal integrity and reduce interference. The module is housed in a compact form factor (40 mm width) and connects via a 20-pin front connector, suitable for central or distributed configurations in control cabinets. It supports diagnostic LEDs for channel status monitoring and uses STEP 7 software for parameterization, including signal range and data format adjustments.
