Product Description:

Bosch Rexroth Indramat manufactured the RZC01.1-6N-022-F-23 as part of the RZC Chemistry Modules series. The module functions as a power and signal conditioning unit within automated chemical processing lines, coordinating drive sections and measurement circuits that operate pumps, mixers, or metering valves. By grouping process-specific interfaces into a single rack-mount format, it simplifies cabinet wiring and helps keep related control functions in one location. This arrangement also supports stable interaction between the power stage and process instrumentation during continuous dosing, blending, and transfer operations.

The RZC module accepts a nominal input of 3 x AC 400 V ±15 % and converts it into regulated bus energy for downstream drives. Its maximum output carrier frequency of 200 Hz suits fast-switching inverters that modulate dosing pumps without audible resonance. At the rated power of 18.5 kW, the internal bus bars deliver up to 35 A of continuous current while staying within the unit's thermal limits. Process equipment in washdown areas is protected by the enclosure's IP23 rating, which resists vertically falling water and coarse dust. A separate standby connection keeps the control electronics active when the main power is isolated, so status monitoring can remain available during shutdowns.

An isolated auxiliary connector for external 24 V standby power keeps PLC memory and diagnostics active during a primary shutdown. For closed-loop accuracy, the board integrates filter current feedback, allowing the drive controller to monitor harmonic content and correct switching patterns in real time. Because it is prepared for cabinet mounting, the unit includes rear heat-sink fins and bus terminals aligned to the standard 300 mm cabinet grid. It is supplied without a NAMUR terminal strip, so any intrinsically safe barriers must be wired on separate rails rather than directly on the module.
