Product Description:

The RZC01.2-5N-011-F-23 is a Chemistry Module manufactured by Bosch Rexroth Indramat and assigned to the RZC Chemistry Modules series. Designed for drive systems that handle chemical dosing or mixing commands, the unit functions as an interface stage between the central converter and the application-specific actuators. In an automation line, it conditions power, monitors feedback, and contributes discrete control signals so that frequency-controlled pumps or agitators follow the required recipe parameters.

The module operates from a three-phase nominal supply of 3 x AC 500 V ±10 %, allowing a ten percent voltage swing without derating. Its inverter section delivers a continuous shaft power of 7.5 kW while drawing up to 14 A; these limits indicate the motor sizes that can be connected on a single channel. The electronics are housed in carrier design 2 from product line 1, and the module supports a maximum output frequency of 100 Hz, so synchronous and induction machines can run above grid speed when process throughput requires it. The enclosure is rated at IP23, which guards against fingers, tools, and water spray falling up to 60 degrees from vertical.

Mechanical integration is simplified because the housing is prepared for cabinet mounting; no separate brackets are needed, and airflow follows the control cabinet’s ventilation path. An auxiliary circuit provides external 24 V standby power, keeping the control electronics active during main-line shutdowns so parameters and diagnostics remain available. The hardware is in Size Class B, which provides a predictable footprint beside other Rexroth converters, and it is supplied without a NAMUR terminal strip, so process sensors can be wired through alternate field terminals. Filter current feedback is included to improve closed-loop accuracy, and there is no integrated brake resistor.
