PLC Rack Power Conversion and Bus Supply Characteristics

The AS-P840-000 performs AC-to-DC conversion for Modicon 984 PLC rack assemblies. Its regulated outputs supply controller logic circuits and connected I/O modules through the rack power distribution structure. The module supports different output configurations based on revision level, including 24 VDC single-output versions and multi-rail DC output versions.

For Schneider Electric PLC platforms, the module operates within the Modicon rack power architecture, providing regulated supply voltage for backplane-connected modules. Proper rack compatibility, connector keying, and voltage selection are required before installation.

Frequently Asked Questions

Q: What input voltage range does the AS-P840-000 support? A: The module accepts 115 VAC or 230 VAC input through a selectable configuration and operates at 50/60 Hz.

Q: Does the AS-P840-000 provide the same output voltage on all revisions? A: No. Output configuration depends on the hardware revision. Revision A provides 24 VDC at 8 A, while other revisions may provide multiple DC rails.

Q: Can the AS-P840-000 be installed outside a Modicon rack system? A: No. The module is designed for Modicon 984 / 800 Series PLC rack mounting and uses the corresponding rack power interface.

Field Installation Guidelines

Install the AS-P840-000 only in compatible Modicon PLC rack assemblies with the correct slot allocation and connector keying position. Verify the AC input selection before applying power.

Maintain separation between AC supply wiring and low-level control signal wiring. Connect protective grounding according to the cabinet grounding scheme and ensure the rack chassis provides a low-impedance grounding path.

For replacement installation, inspect rack connectors, mating contacts, and power distribution terminals for contamination or mechanical damage before inserting the module. Confirm output voltage levels before connecting additional PLC I/O loads.
