BMXP342020
Schneider Electric
Overview
The BMXP342020 is a Processor module in the Modicon M340 automation platform range from Schneider Electric. It is engineered for industrial automation duties within the Modicon M340 or M580 ecosystem.
Application & Technical Notes
As a processor module, the BMXP342020 is intended for deployment in panel-based control cabinets and machine enclosures where Modicon M340 or M580 equipment is installed. It hosts the application program, executes the control cycle and orchestrates I/O scanning, communication and diagnostics for the station.
Key published characteristics include an operating temperature range of 32…140 °F (0…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 (32…140 °F (0…60 °C)); do not exceed it during commissioning or in enclosed panels without airflow. Avoid condensation — the rated humidity is 10…95 % without condensation; store and operate the module in a dry, pollution-degree-appropriate enclosure. Back up the application program and parameter set before any firmware or hardware change; verify the memory/real-time-clock battery where fitted and replace on schedule. Monitor the module health LED and controller diagnostics; plan spares for critical stations to minimise downtime. 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 BMXP342020, 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 the CPU matches your Modicon M340 or M580 architecture, memory size, firmware revision and any required option/communication modules. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
