Product Overview

DO321/B is high‑density digital output module of KEBA KeControl I/O system. It converts internal control logic signals into 24 VDC field‑side driving signals to actuate machine actuators. Built‑in per‑channel short‑circuit and overload protection prevents module damage under field‑wiring fault conditions. Widely deployed for injection‑molding‑machine sequence‑actuator control. Refurbished and surplus tested spare module for production‑machine repair and spare‑part stocking.

Application Notes

‑ Do not exceed each channel maximum load‑current rating. ‑ Pay attention to inductive‑load free‑wheel absorption measure for solenoid loads. ‑ Check back‑plane bus connection after hot‑swap replacement. ‑ Typical deployment: KEBA system digital‑output‑module spare‑part stocking.
