Product Description:

The MTC-R02.1-M1-A2-A2-A2-FW is a controller module produced by Bosch Rexroth Indramat for the MTC200 CNC Modules series. Intended for installation in machine-tool control racks, this unit manages real-time axis coordination and input/output tasks through multiple Sercos fiber-optic rings. By serving as the numerical control core, it links motion drives, operator panels, and PLC peripherals, enabling deterministic communication in automated machining and assembly lines.

Electrical and communication limits show how the module fits into a control cabinet. It operates from a 24 VDC nominal supply, drawing up to 930 mA during normal execution, while internal power conversion releases no more than 26 W of heat that must be removed by the cabinet airflow. Four optical interfaces give a Sercos loop count of 4, and each loop can address 8 drives, allowing flexible segmentation of high-speed axes. The input stage tolerates ripple up to 4 Vpp, so power supplies do not require extreme smoothing, and an inrush limiter stages energization. A ready contact rated at 24 V / 150 mA provides a hardware handshake to external safety relays when the numerical control kernel has completed its boot sequence. Up to 7 concurrent processes can be executed at the same time, distributing PLC logic, interpolation, and diagnostics tasks across the module’s internal CPU.

The housing is compact, measuring 192 mm in height, 83.7 mm in width, and 152 mm in depth. The assembly weighs 1.65 kg, which supports straightforward rail mounting beside I/O terminals. Once powered, the circuit briefly draws a 20 A inrush current that must be considered when selecting supply breakers. The controller supervises as many as 32 drives across the linked loops. The enclosure has an IP 20 rating, so the unit must be installed inside a closed cabinet, and reliable operation is specified up to 55 °C ambient temperature.
