Description
The Bachmann CM202 CANopen Master Module is designed for high-speed, reliable network communication in industrial automation. Each module is equipped with two independent CAN bus interfaces, which can be independently configured as an NMT master or slave according to application requirements, enabling flexible network topologies. The module provides reloadable firmware via FLASH technology for easy upgrades and maintenance, supports protocols compliant with the CiA DS 301 standard, and follows the CiA DS 405 device configuration file, ensuring compatibility with various CANopen devices.

In the M1 controller system, up to four CM202 modules can operate in parallel, enabling the system to manage up to four independent CANopen networks. Each CAN bus can connect up to 64 nodes, with transmission rates ranging from 10 kbaud to 1 Mbaud. The maximum bus length is 5000 meters (requires a signal repeater), and the module provides 500 V isolation protection to ensure network and device safety.

The CM202 features short-circuit protection, operates at only 320 mA @ 5 VDC, has an operating temperature range of -30°C to +60°C, a storage temperature range of 5°C to 95°C, and operates at up to 95% humidity without condensation, making it suitable for complex industrial environments. The module connects via two 9-pin D-Sub female interfaces, ensuring simple and reliable wiring and rapid integration into existing automation systems.

The CM202 CANopen Master Module excels in applications such as machine control, distributed I/O, energy management, and production line automation, providing secure, stable, and flexible communication solutions for industrial networks, making complex control tasks more efficient and reliable.
