The Schneider Electric TWDNOZ485T offers a reliable serial communication solution for the Twido programmable logic controller family. This module provides an RS485 port through an integrated adaptor with a screw terminal block. Engineers prefer the screw terminal design for its secure and maintenance-friendly wiring capabilities. For instance, the TWDNOZ485T supports Modbus RTU and ASCII protocols, making it suitable for diverse industrial applications. Additionally, this compact accessory attaches directly to compatible modular base controllers. Therefore, it saves valuable panel space while delivering stable communication performance.
The TWDNOZ485T provides a robust RS485 serial communication interface for the Twido system. This module features a screw terminal block for all electrical connections. The screw terminal design ensures a vibration-resistant and reliable wiring solution. Furthermore, the TWDNOZ485T supports two distinct communication modes with different speed capabilities. The module achieves a maximum baud rate of 19,200 bps for PC Link applications. Meanwhile, the Remote Link mode allows communication at up to 38,400 bps. Consequently, users can select the appropriate speed for their specific networking needs. This module manages up to seven remote links in a single network. Moreover, it supports a maximum cable length of 200 meters between the base and the final remote device. The RS485 half-duplex communication design makes this module ideal for multi-drop networks. The screw terminal block accepts wire sizes from 0.2 to 2.5 mm², accommodating various field wiring requirements.
The TWDNOZ485T differs from the TWDNOZ485D primarily in its connection method. The TWDNOZ485T uses a screw terminal block for permanent, tool-maintainable connections. This design suits applications where technicians need to access and modify wiring during maintenance. Meanwhile, the TWDNOZ485D uses an 8-pin mini DIN connector, which offers faster plug-and-play connectivity. Engineers working in high-vibration environments often choose the TWDNOZ485T for its secure screw terminals. Conversely, applications requiring frequent cable changes may benefit from the mini DIN version. Both modules share identical compatibility, communication speeds, and protocol support.
The TWDNOZ485T works exclusively with Twido modular base controllers. Specifically, this module is compatible with the following controller models: TWDLMDA20DTK, TWDLMDA40DTK, TWDLMDA40DUK, TWDLMDA20DUK, and TWDLMDA20DRT. Schneider Electric classifies this unit as a separate part within the Twido accessory lineup. Therefore, users can order and install it independently of the main controller. The TWDNOZ485T integrates seamlessly with TwidoSuite configuration software. This software allows engineers to set communication parameters quickly and easily. Additionally, the compact module design does not interfere with other expansion units. Users can add this communication module alongside other I/O or specialty modules. This flexibility makes the TWDNOZ485T a valuable addition to any Twido-based automation system.
The TWDNOZ485T features a rugged construction suitable for demanding industrial environments. Weighing only 0.187 lb (0.085 kg), this module adds minimal weight to the controller assembly. The compact dimensions ensure easy installation in crowded control cabinets. Specifically, the unit measures 3.0 inches in height, 4.1 inches in width, and 5.1 inches in length. The module operates reliably within a temperature range of 0°C to 55°C. Furthermore, it can withstand storage temperatures from -40°C to +70°C without damage. The TWDNOZ485T also handles ambient humidity levels between 10% and 95% (non-condensing). This environmental tolerance ensures consistent performance in various factory conditions. Consequently, users can depend on this module for stable serial communication even in challenging settings.
Installing the TWDNOZ485T requires minimal time and no specialized tools. First, power off the Twido modular base controller completely. This step prevents any potential electrical issues during installation. Next, locate the dedicated expansion port on the side of the controller. Then, align the module's connector with the expansion port on the controller. Gently push the TWDNOZ485T into place until you hear a click. This click indicates a secure connection between the module and the controller. After the physical installation, prepare the wiring for the screw terminal block. Strip the wire insulation to approximately 7 mm for proper insertion. Insert each conductor into the corresponding terminal and tighten the screw securely. Finally, power on the controller system and open the TwidoSuite software to configure the communication settings. Set the baud rate, parity, and protocol according to your network requirements.
