Obsolete ILS integrated drive — what the code covers
The ILS1M571PC1A0 from Schneider Electric is an integrated drive from the ILS series, pairing a stepper motor with onboard drive electronics and built-in 24-36V I/O for motion sequencing, rated at 3.5A. It belongs to the servo drives / integrated motion family, sold as a single assembly rather than a separate drive-and-motor pair, so a replacement board must be qualified against the same motor stack and I/O pin map.
24-36V bus and 3.5A — what those numbers decide
The 24..36V supply range places the unit firmly on the 24 VDC control cabinet rail — the kind of rail a PLC power supply or a small stepper PSU already services, so a retrofit or replacement board can be dropped into the existing backplane wiring without bringing in a separate drive-voltage transformer. The 3.5A rating is the per-phase current ceiling for the integrated stepper output — it bounds how much torque the assembly can deliver through its matched motor, and any replacement has to clear that figure under the same winding configuration or the motion profile shifts.
Sourcing an obsolete ILS board
With the manufacturer status Obsolete, this order code moves outside the standard Schneider Electric catalog window — it lives in independent distribution, where each lot is traceable but not infinite. For a kitting lead filling a BOM line or a field tech trying to clear a downtime ticket, the realistic path is a quoted RFQ: lead time, lot size, and warranty terms get confirmed at quote time rather than pulled from a live stock feed.
