AS-584A-034Modicon 584 Series – Discrete I/O Module (High‑Speed, Isolated)

Product Description AS‑584A‑034 is a high‑speed, isolated discrete I/O module for the Schneider Electric Modicon 584 PLC series (legacy, discontinued). It provides 16 channels of mixed 24VDC input/output with 707VDC group‑to‑bus isolation, sub‑3ms response, and overload protection, designed for high‑reliability industrial control.

Features

16‑channel mixed I/O (configurable input/output per channel) for flexible system design.

High‑speed response (sub‑3ms input, <0.1ms output) for fast event capture and control.

707VDC isolation between channels and bus, enhancing noise immunity in harsh environments.

Per‑channel LED status indicators for real‑time diagnostics and troubleshooting.

Robust overload/short‑circuit protection safeguards module and field devices.

Compact 1‑slot form factor compatible with Modicon 584 backplanes and CPUs.

Applications

High‑speed discrete control: Automotive assembly, packaging machinery, material handling.

Process automation: Water treatment, pharmaceutical, chemical (Class 1 Div 2 hazardous areas).

Legacy system retrofits: Replacement for aging I/O modules in existing Modicon 584 installations.

Key Differences from AS‑521P Series

584 Series vs. Compact Series: AS‑584A‑034 is for the Modicon 584 platform (high‑end legacy), while AS‑521P models are for the Compact line (mid‑range legacy).

Mixed I/O vs. Input‑Only: AS‑584A‑034 supports configurable input/output; AS‑521P modules are input‑only.

Higher Current Rating: 0.5A per output point (vs. 0.144W per input in AS‑521P).
