Core Functions

Expand servo drive I/O for external sensors, switches, and actuators

High‑speed signal handling for motion interlocks and sequence control

Galvanic isolation reduces electrical noise and improves safety

Short‑circuit protection on outputs prevents module damage

Plug‑and‑play installation in drive U‑slots, no external wiring needed

Application Scenarios

CNC machine tools: limit switches, door interlocks, coolant control

Packaging machinery: photoeyes, solenoids, conveyor control

Material handling: sensors, brakes, clamps, safety circuits

Retrofit of Indramat DDS/DDC systems for more I/O points

Multi‑axis automation requiring distributed I/O

Usage and Maintenance

Install only when drive is powered off to avoid damage

Insert into U1–U5 slots and secure with screws

Use shielded cables for field wiring to reduce noise

Keep ambient temperature ≤45 °C for reliability

Inspect D‑sub connectors annually for wear or corrosion
