The TWDNCO1M CANopen bus master module expands the Twido PLC family with powerful fieldbus capabilities. Manufactured by Schneider Electric, this module acts as the central coordinator for CANopen networks. It uses a standard 9-way SUB-D male connector for physical integration. The module handles up to 16 RPDO and 16 TPDO channels simultaneously.
Designed for seamless integration, the Schneider TWDNCO1M works exclusively with Twido base controllers. It is compatible with models such as the TWDLMDA20DRT, TWDLCAE40DRF, and TWDLCAA40DRF. The module requires an external 24V DC supply. This ensures stable operation even in demanding industrial environments.
Power consumption remains efficient for this bus master module. It draws 50 mA from the 5V DC rail. It also consumes 50.5 mA from the 24V DC supply. Total power dissipation is rated at 1.2 W at 24V DC. Each Twido base controller accepts only one TWDNCO1M module. The module supports up to 16 slave devices per network.
Furthermore, the Schneider TWDNCO1M complies with CANopen protocols M10 DR 303-2 and M10 DS 301 V4.02. This ensures interoperability with a wide range of third-party CANopen devices. A single LED indicator provides clear power status feedback. The green PWR LED illuminates when the module receives proper supply voltage.
The TWDNCO1M operates reliably across a temperature range of 0°C to 55°C (32°F to 131°F). For storage, it withstands -25°C to 70°C (-13°F to 158°F). The module carries an IP20 protection rating. This suits it for installation inside control cabinets and protected enclosures.
Mechanically, the module remains compact and lightweight. It measures 7.7 cm in height, 10.5 cm in width, and 12.5 cm in depth. The package weight is only 155 grams. This makes handling and installation convenient. The product bears CE marking and UL certification. These approvals confirm its compliance with international safety and performance standards.
Installing the Schneider TWDNCO1M is a straightforward process. First, ensure your Twido base controller supports the module. Compatible models include TWDLMDA20DTK, TWDLCDA40DRF, and TWDLMDA40DUK. Next, insert the module into the dedicated slot on the controller. Finally, connect your CANopen network using the 9-way SUB-D connector.
It is important to use twisted shielded pair cables for optimal signal integrity. This minimizes electromagnetic interference in noisy industrial environments. The module supports a maximum of 16 slaves per network. Proper termination resistors should be applied at both ends of the CANopen bus. This prevents signal reflections and ensures stable communication.
