Its fast inputs handle 100 kHz counting and pulse tasks. Its digital outputs switch 0.5 A per point. The temperature range and environmental tolerance appear above. The dual-core design and shielded ports support strong noise immunity in industrial cabinets.
Installation Guide
- Mount the controller on a DIN rail inside a dry cabinet.
- Keep IP20 protection in mind. Avoid dust and water ingress.
- Use 24 VDC within 19.2 to 28.8 V. Check polarity before power-up.
- Leave space for airflow. Respect the 0 to +55 °C operating limit.
- Connect Ethernet, CANopen, RS-485, and USB as needed.
- Add up to 7 TM5 or TM2 modules for extra I/O.
- Use the 2 PCI slots for communication or function modules.
- Ground the panel well. Route signal cables away from power lines.
Commissioning and Maintenance
Use SoMachine or EcoStruxure Machine Expert for setup. The software handles configuration, programming, and diagnostics. Fast HSC inputs and reflex outputs simplify motion and counting tasks. The dual-core layout reduces communication jitter. Maintenance teams can swap expansion modules without redesigning the cabinet. Keep firmware and project backups current. Check terminal torque and cabinet filters on a regular schedule. Contact info@oiltechcontrols.com or message +86 158 8020 0923 for commissioning support.
Compatibility
The TM258LD42DT works with TM5 and TM2 expansion modules. It supports Modbus TCP, CANopen master, and Modbus RTU/ASCII. It programs through SoMachine and EcoStruxure Machine Expert. The 2 PCI slots accept optional communication and function modules. This controller fits systems that already use Modicon M258 hardware. It also supports migration from older Modicon platforms when engineers plan the I/O map carefully.
Certifications and Compliance
Schneider Electric builds the Modicon M258 line for industrial use. The series typically carries CE and UL marks for the target markets. Confirm the exact label on your unit before final commissioning. Oiltech Controls verifies each shipped item against the listed configuration.
Packing List
- 1 x Schneider Electric TM258LD42DT controller
- 1 x protective packaging
- 1 x packing slip with model verification
Warranty and Shipping
Every unit includes a 12-month warranty. We test each controller before dispatch. We ship worldwide by FedEx, UPS, and DHL. Tracking details go out after pickup. Ask us for lead times on large orders. Reach info@oiltechcontrols.com or +86 158 8020 0923 for a shipping quote.
Typical Applications
- Packaging machines with fast registration inputs
- Material handling and conveyor control
- Assembly cells with CANopen drives
- Small process skids with Modbus TCP links
- Retrofit projects that need embedded Ethernet
- Counting and pulse tasks up to 100 kHz
Diagnostic Capabilities
The controller reports I/O status through the programming software. Engineers can monitor fast counter values and reflex output states. Ethernet and CANopen diagnostics help isolate network faults. The dual-core design keeps communication tasks separate from program tasks. This separation makes fault tracing easier. Use the USB port for local programming and quick checks. Use the RS-485 link for Modbus RTU or ASCII devices. Keep spare expansion modules on hand for fast swaps.
