Honeywell 8C-PDZPA1 Digital Output Module

Product Introduction

The Honeywell 8C-PDZPA1 Digital Output Module is part of the high-performance Series 8 I/O family used within Honeywell’s Experion PKS architecture. This module is engineered to provide reliable and deterministic digital output control for field devices in mission-critical industrial environments. Designed with high-density I/O, superior diagnostics, and system redundancy support, the 8C-PDZPA1 ensures precise actuation of field components such as solenoids, relays, contactors, and signal lamps.

This module is typically installed in conjunction with the C300 controller and functions within an I/O rack equipped with Series 8 baseplates. The PDZPA1 module supports zoned power switching and output channel group isolation, making it suitable for applications requiring separation of different field voltage levels or grouped control zones.

Engineered to meet Honeywell’s rigorous standards for reliability, the 8C-PDZPA1 is widely used in process industries like oil & gas, refining, chemical, and power generation.
