Schneider Electric AS-B885-100 Motion Module

Schneider Electric’s Modicon AS-B885-100 Motion Module is an intelligent/special‑purpose I/O module in the Modicon 984/800-series family, designed to add dedicated motion‑control capability to a PLC system. It provides one resolver feedback channel for closed‑loop control of a connected servo or drive and is intended for 24 V DC powered configurations. Installation guidance calls for the 24 Vdc power supply, drive cables, resolver and/or encoder cables, and the RS-232 cable used with Modicon Motion Development Software (MMDS) to configure and test motion programs. As part of the Modicon Motion ecosystem, the AS-B885‑100 integrates with MMDS workflows and the broader 984/800-series I/O set, along with related motion accessories for wiring and drive interfaces. Typical use cases include precise positioning and motion sequencing in automation projects that implement Modicon motion tasks, especially where a single resolver feedback path is sufficient for drive control. Do not bundle power wiring with signal wiring to minimize noise and interference during installation.
