RZW02.1-075-060

The RZW02.1-075-060, a braking resistor from Bosch Rexroth Indramat in the RZW Braking Resistors series, is engineered for high-performance motor braking and energy dissipation tasks. It employs a convection-cooled design that leverages natural airflow to manage heat without the need for auxiliary fans. The compact module is DIN rail-mounted for seamless integration into control cabinets, optimizing cabinet space and layout flexibility. Featuring both EtherCAT and Ethernet interfaces, it supports direct communication with modern PLCs and motion controllers.

Measuring a compact 198 mm in length, 70 mm in width, and 35 mm in depth, and weighing just 450 g, the resistor fits into tight cabinet spaces without compromising performance. The convection-cooled design dissipates braking energy through passive airflow paths, ensuring stable operation under continuous duty cycles. Mounting is simplified by a robust DIN rail-mounted housing, and the unit carries an IP20 protection rating to guard against dust ingress and accidental contact. Dual dedicated communication ports—EtherCAT and Ethernet—enable real-time device monitoring, fault diagnostics, and parameter adjustments within distributed automation networks.

Engineers will appreciate the RZW02.1-075-060’s plug-and-play compatibility with variable-frequency drives, which delivers consistent braking torque and mitigates DC-link overvoltage during rapid deceleration. Its passive cooling scheme and IP20 enclosure ensure high reliability in demanding industrial environments with minimal maintenance requirements. Ideal for elevator drive control, crane hoist systems, and wind-turbine pitch regulation, this braking resistor enhances operational safety, uptime, and energy efficiency across a broad range of automation applications.
