HIMA X-DO2401 24-Channel Digital Output Module
HIMA X-DO2401 is a SIL3 safety digital output module for the HIMax safety control system. It provides 24 channels of 24VDC discrete output signals to drive solenoid valves, relays and alarm indicators in safety loops. The module supports line monitoring for short-circuit and open-circuit faults, with built-in overcurrent protection for each channel.

This hot-swappable module adopts 1oo2 safety processor architecture, communicates with HIMax CPU via redundant backplane safety bus. It is certified up to SIL3, Cat.4 PL e, widely deployed for ESD, BMS and SIS protection loops in oil, gas and chemical plants, used as critical maintenance spare parts.
