Frequently Asked Questions (FAQ)

What is SOE (Sequence of Events) recording?

SOE records the exact sequence and timing (1ms accuracy) of status changes across multiple inputs. This is critical for fault analysis in power systems and complex processes.

What types of signals can be connected?

The 369B1843G5003 accepts dry contacts (switch closures) or sink current signals using the 48VDC sensing voltage for reliable detection.

How are the last 4 channels different?

Channels 29-32 support both standard digital input and pulse input counting up to 1.5kHz, making them ideal for flow meters, encoders, or high-speed event counting.

Why is configurable signal filtering important?

Adjustable filtering (3-50ms) allows optimization for different applications—shorter times for fast responses, longer times for noise immunity in electrically noisy environments.

What applications benefit from this module?

This module is ideal for power distribution monitoring, manufacturing process control, equipment status monitoring, and any application requiring precise event sequencing or high-speed counting.
