BOSCH D-64711 DC102/MK – Terminating Module | DC102/MK Series Platform
Engineering Background
The BOSCH D-64711 is a precision-engineered terminating module designed for the DC102/MK drive and control platform — a cornerstone of Bosch Rexroth’s industrial automation architecture. Terminating modules in this series serve a critical bus-integrity function: they provide the correct impedance termination at the end of the backplane or communication bus, preventing signal reflection and ensuring stable, noise-free data transmission across all connected modules.
Product Positioning
Targeted at procurement engineers and MRO specialists maintaining Bosch Rexroth DC102/MK-based control systems in CNC machining centers, press lines, injection molding machines, and automated assembly cells. This module is a mandatory system component — without proper termination, the entire control bus is susceptible to communication faults, spurious errors, and unplanned downtime. Sourced directly from verified OEM channels and rigorously inspected before dispatch.

System Architecture & Signal Flow
In the DC102/MK modular rack system, the backplane bus carries both power distribution and high-speed serial communication signals between the CPU module, I/O modules, and drive interface cards. The D-64711 terminating module is installed at the physical end of the rack to provide the correct characteristic impedance load. Without this termination:
- Bus signals reflect back from the open end, causing data corruption
- The CPU may log intermittent communication errors or enter fault state
- Drive response latency increases, degrading motion control precision
Installation is straightforward: insert the D-64711 into the last available slot of the DC102/MK rack and secure with the standard module locking mechanism. No configuration or parameterization is required.

Technical FAQ
Q: Is the D-64711 compatible with all DC102/MK rack sizes?
A: Yes. The terminating module is designed for use with all standard DC102/MK rack configurations regardless of the number of populated slots.
Q: Can I operate the DC102/MK system without a terminating module?
A: Not recommended. Operating without proper bus termination will result in signal integrity issues and is likely to cause intermittent or persistent communication faults.
Q: What is the difference between part numbers 1070081815-101 and 1070068007-102?
A: 1070081815-101 is the Bosch Rexroth assembly drawing/revision reference, while 1070068007-102 is the orderable SKU used for procurement. Both refer to the same physical module.
Q: Do you offer exchange or repair services?
A: Yes. Contact us to discuss exchange programs for faulty units or repair assessment for modules with physical damage.
Q: What warranty is provided?
A: 12 months from date of shipment, covering manufacturing defects and functional failure under normal operating conditions.
