Product Description:

The RZC01.2-6T-022-F-23 is a modular power and control unit manufactured by Bosch Rexroth Indramat for the RZC Chemistry Modules series. Designed for automated chemical processing equipment, the module combines drive electronics and signal conditioning so that agitators, pumps, and dosing valves can be synchronized with plant controllers. By acting as an intermediary between the facility’s three-phase mains and field devices, it delivers regulated motor power while simultaneously forwarding process feedback to the supervisory PLC. This arrangement supports coordinated operation where motor control and process signaling must remain in step during chemical handling cycles.

It operates from a three-phase supply of 3 x AC 400 V ±15 %, and the wide tolerance window lets the module remain functional when plant voltage sags or surges. The inverter section is rated for a continuous output of 35 A, enabling it to energize motors up to 18.5 kW without thermal derating. A carrier and modulation scheme extends motor speed to a fundamental frequency ceiling of 200 Hz, allowing high-speed agitation or centrifugal separation where the process requires it. The housing has an IP23 rating, so the surrounding enclosure must keep out larger particles and water that does not fall vertically. The mechanical layout is design 2 in line 1 execution, which indicates the connector spacing and cooling clearances used for cabinet mounting.

A supplementary supply of 24 V standby power keeps the control logic energized during mains isolation. The integrated filter current feedback channel forwards residual-current data for fault detection and status monitoring. For intrinsically safe field signals, a NAMUR-terminal strip is prewired on the front plate, eliminating the need for separate interface blocks. The module belongs to size class C, so its footprint and airflow paths match other C-class units in the drive rack.
