Features:
- SM331 Resistance Input Module for the documented SIMATIC S7-300.
- Rated value (DC): 24 V DC.
- Input current from load voltage L+ (without load), max.: 240 mA.
6ES7331-7PF01-0AB0 belongs to the SIMATIC S7-300 and performs the documented sm331 resistance input module role in the Siemens SIMATIC S7-300 automation system. The retained technical evidence records Rated value (DC): 24 V DC; Input current from load voltage L+ (without load), max.: 240 mA; from backplane bus 5 V DC, max.: 100 mA. The full marking, receiving hardware, connectors or terminals, configuration dependencies and installed position must be matched before substitution.
For installation, retain the SIMATIC S7-300 receiving position, connector or terminal arrangement and configuration record. After power restoration, review diagnostics and test the affected operating path before process release.
The 6ES7331-7PF01-0AB0 SM331 Resistance Input Module is supplied only after the complete hardware identity, condition and current OEM lifecycle status have been confirmed.

Important Notice: The uploaded PDF documents 6ES7331-7PF01-0AB0 or its identified product family. Confirm the complete order code, hardware revision and installed-system requirements before replacement. Accessories, cables, software and certificates are included only when stated in the quotation. All prices are shown in USD.
Signal Handling: 6ES7331-7PF01-0AB0 performs the sm331 resistance input module function within the SIMATIC S7-300. The retained documentation identifies rated value (dc) as 24 V DC; apply that value only to this documented execution.
Match the complete label, hardware form and functional position before transferring any setting, cable or termination from the removed unit.
Hardware Fit: approve 6ES7331-7PF01-0AB0 only for the documented Siemens SIMATIC S7-300 automation system. Compare rack, carrier or panel generation, connector keying, terminal numbering and all paired assemblies with the installation drawings.
Photograph both sides and the installed position before removal so revision markings, jumpers, addressing and channel allocation can be reconstructed accurately.
Function Review: isolate the equipment, remove stored energy and inspect the receiving hardware before installing 6ES7331-7PF01-0AB0.
Restore power in the approved sequence, review status and diagnostics, then test every affected control, signal, relay, communication, protection or monitoring path against the commissioning record.
