GE IS220PDOAH1A Discrete Output Module with 12 Relays Control DC-37 Pin Connector and Proportional Digital Output

The GE IS220PDOAH1A is a Proportional Digital Output Module manufactured by General Electric as part of the Mark VIe Series, designed for use in GE Distributed Gas Turbine Control Systems.

The PDOA module provides the electrical interface between one or two I/O Ethernet networks and a discrete output terminal board. It consists of a processor board common to all Mark VIe distributed I/O packs and an acquisition board specifically designed for discrete output functions.

Key Features:

• Controls up to 12 relays with terminal board-specific feedback
• Supports electromagnetic relays (TRLYH1B, C, D, and F terminal boards) and solid-state relays (TRLYH1E boards)
• Input through dual RJ45 Ethernet connectors and three-pin power input
• Output through DC-37 pin connector directly to terminal board
• Visual diagnostics via indicator LEDs
• Local diagnostic serial communications through infrared port
• VersaMax system provides snap-together I/O carriers for maximum wiring flexibility
• Supports module hot insertion and removal
• Compatible with IEC box-style, spring-style, and barrier-style terminals
