The TWDLMDA40DTK from Schneider Electric's Twido series represents the pinnacle of modular control in the Twido lineup. Operating on a 24 V DC supply, this base controller delivers 40 discrete I/O points, comprising 24 digital inputs and 16 transistor outputs. The transistor outputs are sourcing type, enabling high-speed switching for demanding applications. This model also includes a built-in analog input with 9-bit resolution, plus PWM and PLS positioning functions. Furthermore, the TWDLMDA40DTK supports up to 7 expansion modules, providing exceptional flexibility for growing system requirements. With floating point and trigonometric calculations available, this controller tackles complex control tasks with ease.
The TWDLMDA40DTK provides 24 discrete DC inputs with a voltage range of 20.4 to 26.4 V. These inputs are sink or source configurable, accommodating various wiring schemes. Inputs I0.0, I0.1, I0.6, and I0.7 draw 5 mA with 5700 Ohm impedance, while inputs I0.2 to I0.5 and I0.8 to I0.23 operate at 7 mA with 4700 Ohm impedance. For outputs, the controller features 16 transistor outputs that are sourcing type. Each channel delivers 0.36 A, with a common current of 1 A. The first two outputs (Q0.0 and Q0.1) achieve blazing-fast response times of just 5 µs, ideal for high-frequency pulse applications.
A valuable built-in feature of the TWDLMDA40DTK is its analog input channel. This input accepts a 0 to 10 V signal and offers 9-bit resolution. The input impedance is 100,000 Ohms, ensuring accurate signal acquisition without loading the source. Consequently, you can monitor process variables like temperature, pressure, or flow without purchasing a separate analog module. This integration reduces both cost and panel space requirements significantly.
This modular controller requires a rated supply voltage of 24 V DC, with acceptable limits from 20.4 to 26.4 V. Total power consumption for the base unit with 4 expansion modules is ≤ 19 W. The internal fuse provides protection against overcurrent faults on the power supply. Inrush current reaches up to 50 A for the power supply and 1 A for transistor outputs. Additionally, the lithium battery maintains internal RAM data for 30 days, with a 15-hour charging time and a 10-year operational life.
For connectivity, the TWDLMDA40DTK includes a non-isolated serial link via mini DIN connector. This link supports Modbus RTU/ASCII protocol in both master and slave modes on an RS485 network, operating at up to 38.4 kbit/s. The controller provides 3000 instructions of program memory, expandable to 6000 instructions with an optional 64 K memory cartridge. It includes 128 timers, 128 counters, 256 internal bits, and 3000 internal words. Notably, this model supports floating point and trigonometric calculations, a significant upgrade over lower-end Twido controllers.
The TWDLMDA40DTK excels in motion-related applications with its built-in positioning functions. It supports two channels of PWM (Pulse Width Modulation) or PLS (Pulse Train) outputs at 7 kHz. For counting, the controller includes two 32-bit channels at 20,000 Hz and two 16-bit channels at 5,000 Hz. Therefore, this controller handles stepper motor positioning, encoder counting, and speed control tasks without additional hardware. The two free slots accept 32 K or 64 K memory cartridges and a real-time clock cartridge for expanded functionality.
The TWDLMDA40DTK maintains a compact footprint despite its high I/O density. It measures 90 mm in width, 95 mm in height, and 70 mm in depth. The unit weighs only 0.18 kg, remarkably light for a controller with 40 built-in I/O points. This small size ensures efficient use of valuable panel space.
Engineered for industrial environments, this controller operates from 0 to 55 °C and stores between -25 and 70 °C. It functions reliably in 30% to 95% non-condensing humidity. The unit carries an IP20 protection rating, making it suitable for installation inside control cabinets. Moreover, it holds UL and CSA certifications, meeting rigorous international safety standards for industrial equipment.
The TWDLMDA40DTK demonstrates robust resistance to mechanical stress. On DIN rail mounting, it withstands vibrations of 0.075 mm from 10 to 57 Hz and 1 gn from 57 to 150 Hz. With the optional fixing kit for panel mounting, it tolerates 1.6 mm from 2 to 25 Hz and 4 gn from 25 to 100 Hz. For shock, it handles 15 gn for 11 ms. These specifications guarantee stable performance in harsh industrial environments.
Install the TWDLMDA40DTK on a standard 35 mm symmetrical DIN rail. Hook the top edge onto the rail and press the bottom firmly until the clip engages securely. For panel or plate mounting, use the optional fixing kit to secure the controller. The two free slots accommodate 32 K or 64 K memory cartridges and a real-time clock cartridge, enabling expanded memory and time-stamping functions.
Connect the 24 V DC power supply to the designated terminals on the HE-10 connector. Wire your 24 input devices and 16 transistor output loads according to the sink/source configuration. The HE-10 connector supports high-density wiring, streamlining installation. For the analog input, connect your 0 to 10 V signal source to the dedicated terminal. Finally, use the mini DIN connector for Modbus serial communication to your network.
The TWDLMDA40DTK supports up to 7 I/O expansion modules, the maximum in the Twido range. Attach these modules directly to the right side of the base controller. The system automatically recognizes each module upon power-up, simplifying configuration. With full expansion, you can achieve up to 264 I/O points with HE-10 connectors, 208 points with spring terminal blocks, or 152 points with removable screw terminal blocks.
