Frequently Asked Questions (FAQ)

• What is "negative (source) logic"? It means the input is active (ON) when the field device (like a PNP sensor) sources current into the module's terminal (applies 24V). The common terminal is connected to 0V.
• What devices can connect to it? PNP-type proximity sensors, mechanical switches (dry contacts), and other devices that can switch a 24V DC signal relative to common.
• How fast can it read inputs? With a ≤1 ms response time, it can detect very fast state changes, suitable for high-speed counting or event detection.
• What do the 4 channel groups mean? The 32 inputs are divided into 4 electrically isolated blocks. A fault or voltage spike in one group is less likely to affect inputs in another group.
• What is the conformal coating for? The Humiseal coating protects the internal circuitry from moisture, dust, and corrosive gases, essential for longevity in harsh industrial environments.
• How is it addressed in the PLC? It uses 2 consecutive 16-bit input words in the Quantum PLC's I/O mapping, giving you 32 bits of data (one per channel).
• Is it suitable for wet or dusty areas? While the coating provides protection, the module itself is designed for installation inside a protected enclosure (IP rating not specified for the module alone).
