Product Description:

The RZC01.2-6N-037-F-23 chemistry module is produced by Bosch Rexroth Indramat and belongs to the RZC Chemistry Modules series. As a dedicated chemistry module, it conditions and delivers controlled three-phase power to drive elements used in dosing, mixing, or reaction control stages of an automated process line. By combining power conversion with feedback interfaces, the unit simplifies cabinet wiring and lets a higher-level controller focus on process logic rather than direct power regulation. This arrangement supports coordinated motor operation where stable electrical output and monitored drive behavior are needed throughout the process.

The module operates from a nominal supply of 3 x AC 400 V with a tolerance of ±15%, matching common factory mains. Under continuous duty, it can deliver 56 A of line current, which corresponds to a thermal rating of 30 kW for medium-sized pumps or agitators. Its inverter section can generate output frequencies up to 200 Hz, so peripheral motors are not limited to standard 50 or 60 Hz speeds. When grid power is absent, an auxiliary rail provides 24 V standby power, allowing the control electronics to remain active for diagnostics or safe shutdown routines. An enclosure rating of IP23 indicates protection against finger contact and against water drops falling at angles up to 60 degrees from vertical, which suits equipment installed inside ventilated cabinets.

Mechanical integration follows Design 2 and Line 1. The module is classified as Size Class C, which keeps its footprint consistent with other C-frame drive components in the same platform. Internal analog capture of phase-leg currents is refined by filter current feedback, a feature that improves torque linearity and reduces harmonics sent back to the mains. Because the hardware is prepared for cabinet mounting, no external brackets are required, and the unit is intended for direct integration with bus bars and cabinet cooling airflow. The design omits a NAMUR terminal strip, so discrete sensor loops are routed through separate I/O hardware rather than through this power stage.
