Product details

Overview

The ILS2K851PB1A0 is a Schneider Lexium integrated drive combining a 3-phase stepper motor and drive electronics in a single IP41-rated housing. It operates on 48 V DC, delivers 2 N.m holding torque, and supports Ethernet/IP and RS485 Modbus TCP communication. The unit is CE marked and carries a 6-pole winding with medium-speed/medium-torque characteristics. Schneider has discontinued this model.

Schneider lists the ILS2K851PB1A0 as obsolete with no direct successor. Sourcing now relies on surplus and broker channels.
