Product Overview
Constructed with a dual-board design, the IS220PDIAH1A integrates a universal processor board (shared across all Mark VIe distributed I/O packs) and a specialized discrete input acquisition board, which work in tandem to optimize signal processing efficiency and system compatibility. Capable of accepting up to 24 contact inputs, it caters to large-scale industrial setups requiring simultaneous handling of multiple signals. Its adaptability is further enhanced by support for three distinct voltage levels (via TBCIH1, H2, and H3 terminal boards) and compatibility with isolated discrete input boards featuring voltage sensing (TICI boards), making it a versatile solution for diverse industrial scenarios.

Features
Expansive Input Handling & Adaptability
The IS220PDIAH1A is built to manage up to 24 contact inputs, allowing for concurrent processing of numerous discrete signals—an essential feature for industrial systems with high input requirements. Its ability to work with three voltage levels (through TBCIH1, H2, and H3 terminal boards) and support for TICI boards (isolated discrete input with voltage sensing) ensures it can integrate smoothly with a wide range of terminal configurations, reducing compatibility issues.
Robust Signal Isolation
Each input on the IS220PDIAH1A is isolated from the control logic using an opto-coupler paired with an isolated power supply. This design minimizes electrical interference, safeguards against voltage spikes, and enhances overall signal integrity—critical for maintaining stable operation in industrial environments prone to high electromagnetic interference (EMI).
Intuitive Diagnostic Capabilities
Onboard yellow status LEDs provide clear visual feedback for each of the 24 inputs: they light up when an input is active (“picked up”) and turn off when inactive (“dropped out”), enabling quick on-site troubleshooting. Additionally, an infrared port supports local diagnostic serial communication, simplifying remote monitoring and maintenance procedures.
Redundant Network Support
Equipped with dual RJ45 Ethernet connectors, the module offers redundancy for I/O Ethernet networks. This ensures uninterrupted data transmission even if one network fails, a key advantage for mission-critical applications where operational downtime could result in significant losses.
Applications
The IS220PDIAH1A GE Mark VIe Discrete Input Module is tailored for use in challenging industrial settings, including:
Turbine Control Environments
As an integral part of the GE Mark VIe Control System, it plays a pivotal role in turbine control systems. It processes discrete signals from sensors and actuators, aiding in monitoring and regulating turbine performance to ensure efficient, safe, and consistent operation.
Distributed Control Systems (DCS)
It integrates seamlessly with major DCS architectures, such as Emerson DeltaV and Foxboro I/A Series, to collect and transmit discrete data. This supports centralized control and monitoring of industrial processes, enhancing operational efficiency and decision-making.
Industrial Automation Facilities
In manufacturing plants, power generation stations, and oil & gas refineries, the IS220PDIAH1A handles discrete input signals from switches, relays, and other devices. This enables automated process control, optimization, and real-time adjustment based on input data.
Machinery Protection Setups
Working alongside machinery protection systems like Bently Nevada 3500 and VM600, it processes equipment status signals, contributing to predictive maintenance efforts and early fault detection, thus extending machinery lifespan and reducing unplanned downtime.
