Bachmann CM202 CANopen Master Module

Description The Bachmann CM202 is a CANopen master module designed for industrial automation applications. It operates on the Controller Area Network (CAN), which is a widely-used fieldbus system known for its reliability and flexibility. The CM202 can handle up to two separate networks per module and can be configured independently as either an NMT master or slave.

Features

• Multiple Masters: Supports up to 4 CANopen master modules per M1 controller.
• Independent Networks: Each module can operate up to 2 independent CAN buses.
• Configurable Roles: Can be used as an NMT master or slave.
• High Transfer Rates: Supports data transfer rates from 10 Kbaud to 1 Mbaud.
• Long Bus Length: Capable of bus lengths up to 5000 meters with the use of signal repeaters.
• Galvanic Isolation: Provides 500V isolation between the system and interfaces.
• Short Circuit Protection: Ensures durability and safety in industrial environments.
