The independent Bus module connects the diagnostic device (DDL) with S-design and has the material number 00128826. It supports the field bus protocols Profibus DP / INTERBUS-S / CANopen / EtherCAT / DeviceNet. The operating temperature range is +5°C / +50°C and the protection class is IP 65. The operating voltage of the electronic device is 24 V DC. The voltage tolerance of the electrical devices is -20% / +20%. The operating voltage of the valves is 24 V DC. The total current of the valves is 3 A. The maximum piston rod (DDL) is 40 m. The maximum number of DDL participants is 14. The number of input terminals is 128 through the connection structure and the number of output terminals is 128 through the connection structure.
The document describes the DDL connection structure and associated bus modules used with various fieldbus protocols such as Profibus DP, INTERBUS‑S, CANopen, EtherCAT and DeviceNet. It lists part numbers, connector types (M12x1 with A, B, D coding), and provides wiring diagrams for bus input, bus output, DDL and power connectors.
Technical data include environmental limits, protection ratings, operating voltage, current limits, and material specifications for both the modules and the cable assemblies. Contact information for Bosch Rexroth sales offices worldwide is also provided. This manual is written in Chinese.
