TM3DM24R
Schneider Electric
Overview
The TM3DM24R is a Discrete I/O module in the Modicon TM3 range from Schneider Electric. It is engineered for industrial automation duties within the Modicon TM logic controller / I/O ecosystem.
Application & Technical Notes
As a discrete i/o module, the TM3DM24R is intended for deployment in panel-based control cabinets and machine enclosures where Modicon TM logic controller / I/O equipment is installed. It localises I/O close to the field devices, reducing wiring length and bringing intelligence to the periphery of the installation.
Key published characteristics include an operating temperature range of -10...55 °C for horizontal installation, top hat type th35-15 rail conforming to iec 60715 mounting. 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 (-10...55 °C for horizontal installation); do not exceed it during commissioning or in enclosed panels without airflow. For storage and transit, keep the unit within -25...70 °C. Avoid condensation — the rated humidity is 10...95 % without condensation in operation; store and operate the module in a dry, pollution-degree-appropriate enclosure. Verify field wiring, shielding and grounding at installation; check terminal torque and confirm signal types match the configured range. Periodically inspect for loose terminations, induced noise and channel-level diagnostics reported by the controller. 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 TM3DM24R, 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 module matches your Modicon TM logic controller / I/O rack, the required channel count, signal type and voltage, and the firmware/configuration of the controller. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
