Product Description
This discrete output I/O module is designed for Modicon 984/800 Series systems, providing 32 DC outputs organized in four groups with eight outputs per group. It operates from a 24 VDC external supply within a 20–28 VDC range and supports typical industrial loads with a maximum of 0.5 A per point, 4 A per group, and 12 A per module. Fast switching performance is specified at 1 ms for both on-to-off and off-to-on transitions, with typical leakage current of 1 mA at 30 VDC. The module occupies one rack slot and requires controller backplane power of 5 V at 160 mA and 4.3 V at 1 mA, with no -5 V consumption. It is suitable for applications needing reliable, high-density discrete outputs and integrates via the AS-8534-000 terminal connector. Operating temperature is rated 0 to 60°C. This unit is compatible with Schneider Electric Modicon 800 Series architectures and is identified by part number AS-B838-032.
