I. Product Overview

DF9201221-B0N is a safety-redundant analog servo interface board specifically designed for industrial robot controllers. B0N is the safety-enhanced redundant version, integrating analog command output, encoder feedback, dual-channel safety verification, and servo enable safety circuit.

It is mainly used for the **±10V analog speed / torque commands** output for external servo axes, tooling, and traveling axes, and also integrates PL d / SIL2 level safety monitoring. It is suitable for high-safety requirement workstations such as automotive welding, stamping, and human-machine collaboration.

VII. Installation and Usage Tips Installed in the DX200 / YRC1000 VME expansion slot

The safety signal lines and power lines are routed separately, with a spacing of ≥ 100mm

Replace the B0N of the same model without hardware jumper wires. Just check the safety and axis parameters

After installation, it is necessary to perform safety circuit verification and analog zero-point calibration

VIII. Typical Applications

Simulated quantity control of external servo axes, tool changer, and walking axes of robots

Safety interlock for automotive welding and assembly lines using PL d/SIL2

Safety servo signal interface for human-machine collaboration workstations

Servo expansion for automated production lines requiring redundant safety design
