Product Description:

The RZC01.2-6T-037-F-23 is a chemistry module manufactured by Bosch Rexroth Indramat and delivered within the RZC Chemistry Modules series. In a processing line, the unit functions as a power interface that conditions three-phase energy for drive sections used in dosing pumps, mixers, or other electrically driven equipment common to chemical production cells. By integrating this module into a larger automation rack, the system can match motor speed to reaction demands while preserving enclosure space and simplifying cabinet wiring.

The module supplies motors from a nominal input of 3 x AC 400 V ±15 % and can generate output frequencies up to 200 Hz, allowing synchronous or induction machines to run well above network frequency when fast agitation is required. Its continuous output capability is rated at 30 kW with a steady-state phase current of 56 A, and these values indicate the thermal and conductor sizing limits for connected loads. An IP23 housing protects against vertically falling water and objects larger than 12 mm, which is suitable for protected indoor areas. Mechanical preparation for cabinet mounting simplifies integration because no separate chassis drilling pattern is needed. The module is design 2 in line 1.

An auxiliary supply with external 24 V standby power maintains the control electronics when the main three-phase feed is isolated, so parameter memory and fieldbus nodes remain powered during service stops. Accuracy during dynamic torque changes is enhanced through filter current feedback, which sends a conditioned measurement of motor current back to the control board for closed-loop regulation. The enclosure falls under Size Class C, giving a clear expectation of heat load and footprint. Field terminations are simplified by a NAMUR terminal strip that accepts intrinsically safe sensor circuits used in process instrumentation.
