Product Description:

The RZC01.2-6T-045-F-23 is a Chemistry Module produced by Bosch Rexroth Indramat for the RZC Chemistry Modules series. It is used in automated chemical process skids where drive inverters, dosing pumps, and analytical sensors share a common power backbone. By combining line-side filtering with feedback channels, the module helps maintain stable motor torque and precise reagent flow under changing thermal or load conditions inside an enclosure or machine frame.

This module is designed for a mains supply of 3 x AC 400 V ±15 %, allowing installation on plants that use standard European factory power. Under nominal conditions, it delivers a continuous phase current of 68 A, matching mid-range induction or synchronous motor groups often found on mixers or centrifuges. At that current, the unit can provide up to 37 kW of output power, which supports the combined mechanical load of the connected axes. The internal inverter section switches at frequencies up to 200 Hz, so drive regulators can run motors well above base speed for high-throughput washing or agitation steps. For protection against dust ingress and dripping liquids, the housing carries an IP23 rating, which is adequate when the module is installed inside the prescribed switchgear bay. The module is prepared for cabinet mounting, so no subplate drilling or special brackets are required when it slides into the designated rack.

An auxiliary supply line provides external 24 V standby power, keeping the control electronics active during main disconnect events and enabling soft restarts. Signal wiring is consolidated on a NAMUR terminal strip, simplifying loop checks for pH probes or conductivity meters while supporting intrinsically safe layouts. The hardware occupies the C size class, and coding identifiers Design 2 and Line 1 confirm compatibility with the filter current feedback stage used in this version.
