Product Description:

The RZC01.2-5T-022-F-54 is a power conversion module manufactured by Bosch Rexroth Indramat for the RZC Chemistry Modules series. Designed for automated chemical processing lines, it connects the facility’s three-phase mains to motor drives while providing controlled output and diagnostic points for plant supervision systems. Its role is to supply regulated frequency, current, and auxiliary control signals required by pumps, mixers, and dosing units used in continuous or batch reactors.

In design version 2 of line 1, the module accepts a nominal input of 3 x AC 500 V ±10 % and supports loads up to 18.5 kW, drawing a rated current of 28 A under base conditions. The integrated inverter can modulate the output up to 100 Hz, allowing connected induction machines to operate above base speed for higher process throughput. Sealing to IP54 protects against dust ingress and splashing liquids while permitting door-mounted heat dissipation within a ventilated cabinet. The unit is classified as Size class C, which provides fixed height and depth references for multi-axis rack layouts. The mechanical layout is prepared for cabinet mounting so the enclosure can be fastened directly to back panels without additional adapters. Internally, laminated bus conductors and low-inductance paths help minimize switching loss.

A separate 24 V stand-by power terminal keeps the control electronics active during mains outages, supporting orderly restart behavior when power returns. The built-in filter current feedback channel feeds measured phase currents to the supervisory drive, allowing adaptive current limiting and quick isolation of earth faults common in electrolytic processes. Field sensors for limit, flow, or level signals can be connected on the integrated NAMUR terminal strip, which reduces the need for external junction boxes and keeps intrinsically safe loops within the same enclosure.
