Honeywell |DC-PDIS51|Digital Input Sequence of Events Module
Description
The DC-PDIS51 is a digital input module designed to accept 24VDC discrete signals and provide time-tagged sequence of events (SOE) with 1ms resolution. It supports three modes of operation: Normal, Sequence of Events, and Low Latency, ensuring flexibility in different application requirements. The module features extensive internal diagnostics, optional redundancy, and galvanic isolation, making it suitable for reliable and precise event recording in industrial environments.
Features
