Siemens 6SL3256-0VE00-6AA0 SINAMICS V20 I/O Extension Module 2 DI 2 Relays VFD Accessory

The Siemens 6SL3256-0VE00-6AA0 is an I/O extension module for the SINAMICS V20 variable frequency drive, adding 2 digital inputs and 2 relay outputs to the drive's onboard terminal set. It mounts directly onto the V20 control unit and gives the drive additional interlock and feedback points without a separate PLC I/O card. Net weight is 0.07 kg.

Technical Specifications

Selection Notes

This module is the option for V20 installations that need extra digital inputs or relay outputs beyond the drive's built-in terminals, for example an additional run-feedback contact or a second start/stop interlock from an external circuit. It attaches to the same SINAMICS V20 control unit slot used by other V20 option boards, so only one extension can be fitted per drive.

Applications

Used on SINAMICS V20 drives in pump, fan, and conveyor applications where the process needs extra digital signaling, such as a fault relay to an external annunciator or a second interlock input from a safety switch, without adding a separate PLC I/O module.
