990NAD23000
Schneider Electric
Overview
The 990NAD23000 is a Junction Box in the Modicon range from Schneider Electric. It is engineered for industrial automation duties within the the Schneider Electric automation portfolio ecosystem.
Application & Technical Notes
As a junction box, the 990NAD23000 is intended for deployment in panel-based control cabinets and machine enclosures where the Schneider Electric automation portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed Schneider Electric platform.
Key published characteristics include a Range 24 V DC rating, an operating temperature range of -20°C to +60°C. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Respect the published operating temperature window (-20°C to +60°C); do not exceed it during commissioning or in enclosed panels without airflow. Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the 990NAD23000, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Confirm mechanical and electrical compatibility with your the Schneider Electric automation portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
