IV. Core Functional Characteristics

High-density I/O Configuration

Integrated 64 Digital Inputs / 64 Digital Outputs, 24VDC standard industrial level, meeting the expansion requirements of large fixtures and multi-station linkage signals.

All Electrical Isolation Design

All I/O channels are independently optically isolated, with high isolation withstand voltage, effectively isolating on-site frequency converters, welding machines, etc. from strong electromagnetic interference, protecting the internal circuitry of the controller.

General Level Adaptation

Inputs support source type / leakage type without hardware switching, automatically adapting to the PNP/NPN type of external sensors; Outputs are transistor-driven, with independent overcurrent protection for each channel.

High-speed Response and Software Filtering

I/O hardware response time < 0.5ms, software filtering time can be customized in the teaching device parameters, suppressing mechanical contact jitter and interference noise.

Real-time Bus Communication

Through VME bus with high-speed interaction with the main control, I/O status is mapped to the robot program address, supporting direct program reading, interrupt triggering, position synchronous output.

Self-Diagnosis and Status Indicators

The board has its own power supply, operation, fault, communication, input/output status indicators, enabling quick identification of channel faults, power abnormalities, and bus disconnection issues.
