Schneider TWDLMDA40DTK Twido Programmable Controller
The Schneider TWDLMDA40DTK is a compact programmable logic controller from the Twido series, offering a cost-effective solution for small to medium machine control. This unit integrates 40 digital I/O points, a built-in power supply, and multiple communication interfaces, making it a self-contained controller for stand-alone applications.
I/O Configuration
The module includes 24 digital inputs (24 VDC, sink/source, with 4 high-speed counters up to 20 kHz) and 16 transistor outputs (PNP, 0.5 A, 24 VDC, with 2 PWM outputs). All I/O are accessible via removable spring-clamp terminals. The outputs are short-circuit protected and have status LEDs.
Processor and Memory
Powered by a 32-bit CPU running at 40 MHz, the controller has 128 KB of user program memory and 64 KB of data memory. Scan time is typically 0.5 ms for 1K instructions. It supports up to 256 internal flags, 128 timers, and 128 counters.
Communication Ports
The unit is equipped with one RS-232 port (programming/Modbus), one RS-485 port (Modbus RTU), and one Ethernet port (10/100 Mbps) supporting Modbus TCP and web server functions. A USB port is also provided for program transfer and data logging.
Programming Software
Programming is done using TwidoSoft or EcoStruxure Machine Expert - Basic, supporting ladder and instruction list languages. The software includes function blocks for PID, math, and communication.
Power Supply
Integrated power supply accepts 100-240 VAC (50/60 Hz) and provides 24 VDC at 300 mA for external sensors (isolated). The PLC consumes approximately 30 W.
Environmental and Mechanical Data
Operating temperature: -10 to 55°C, storage: -40 to 70°C. Mounting on 35 mm DIN rail. Dimensions: 160 mm x 100 mm x 70 mm (H x W x D). Protection: IP20. Weight: 0.5 kg.
Expansion Capability
The controller can be expanded with up to 7 additional I/O modules (digital, analog, temperature) from the Twido range, allowing up to 168 I/O points.
Applications
Ideal for packaging machines, conveyor systems, small material handling, and HVAC equipment. Its compact size and integrated Ethernet make it suitable for IoT-enabled devices.
Diagnostics and Security
Status LEDs for power, run/stop, and I/O. Built-in watchdog and password protection for program security.
Certifications
CE, UL, and CSA approved. Compliant with EN 61131-2.
In summary, the Schneider TWDLMDA40DTK Twido PLC provides a versatile, compact automation controller with ample I/O and networking, ideal for cost-sensitive machine builders.
