Honeywell DC-PDIS51 Experion Series C Digital Input Module

The DC-PDIS51 is a 32-channel digital input module manufactured by Honeywell for the Experion Series C I/O system platform. Operating on a nominal 24 VDC input voltage, it monitors field discrete devices such as limit switches, proximity sensors, and alarm contacts, converting binary process states into digital signals for control logic execution.

Channel Circuitry and Field Compatibility

The module provides 32 individual channels configured for Form A dry contact input signals. Each channel requires a minimum input current of 2 mA at 24 VDC nominal voltage, ensuring reliable contact sensing across field wiring circuits.

Electrical Isolation and Mounting

To protect system logic electronics from industrial electrical noise and field transients, the module features 1500 V isolation between input channels and internal power supply lines. The unit is designed for standard DIN rail mounting within Experion Series C cabinet assemblies.
