Description
Product Overview
The GE IS220PDIOH1A Discrete I/O Module is a compact and versatile I/O pack from the Mark VIe Series, designed to interface Ethernet networks with discrete input/output terminal boards. It combines the functionality of both PDIA and PDOA modules into a single unit, streamlining control system architecture.
This module supports up to 24 contact inputs and 12 relay outputs. It includes a BPPx processor board and a dedicated acquisition board for discrete signal processing. Input/output signals are routed through a DC-62 connector, while system communication is handled via dual RJ-45 Ethernet ports and a three-pin power input. Diagnostic LEDs provide real-time status visibility.
