Product Introduction
-
Brand: GE
-
Series: Mark VIe Discrete I/O Modules
-
Model: IS220PDIOH1BG
-
Product Type: Discrete Input/Output Module (combines discrete inputs and outputs)
-
Description: The IS220PDIOH1BG is a rugged industrial-grade I/O pack module designed for the Mark VIe control system. It handles discrete inputs (e.g., field switches, contacts) and discrete outputs (e.g., relays, solenoids) in one module, facilitating a more compact I/O rack layout. High electrical isolation, robust network connectivity, redundancy and suitability for heavy‑duty industrial or hazardous area environments mark this module as a premium choice for critical automation systems.
-
Series Info: This belongs to the Mark VIe I/O module series, tailored for power‑generation, petroleum/chemical process control and other high‑reliability applications.

Applications
Typical application areas for the IS220PDIOH1BG module include:
-
In power‑generation plants: for turbine and generator control cabinets, collecting discrete signals (valves, limit switches, alarms) and driving discrete actuators or relays.
-
In oil & gas or petrochemical installations: where discrete field devices must be managed in hazardous or explosive‑gas environments, requiring certified modules with high isolation and redundancy.
-
In heavy industrial automation: manufacturing, large process plants, where mixed discrete I/O (inputs + outputs) modules simplify cabinet footprint and wiring logistics.
-
In distributed control / PLC systems: as part of a Mark VIe I/O rack or Ethernet I/O network to expand discrete I/O capacity, support diagnostics, and deliver high reliability in demanding environments.
Advantages
The IS220PDIOH1BG module offers several key advantages:
-
Combined Input/Output Functionality – By integrating both discrete inputs and outputs into one module, it reduces cabinet space and wiring complexity.
-
High‑level Isolation – Each channel is electrically isolated from others and from ground/backplane, improving signal integrity and reducing interference.
-
Redundant Network Capability – Dual Ethernet ports provide network redundancy, enhancing system uptime and reliability.
-
Hazardous Area Ready – Designed and certified for use in explosive or flammable gas atmospheres when installed per the standards.
-
Compact & Lightweight – At around 1.5 kg and modest dimensions (~20×12×6 cm), it allows efficient control‑rack layout and ease of installation.
-
Industrial Temperature Range – With a wide working temperature range (‑30 °C to +65 °C), the module is suitable for harsh environments.
-
Seamless Integration – Fully compatible with Mark VIe architecture, including racks, I/O backplane, diagnostic tools and network infrastructure.
-
Rapid Diagnostics – Front‑panel indicators plus network diagnostics enable faster fault isolation and maintenance, reducing downtime.

FAQ (Frequently Asked Questions)
Q1: Can the IS220PDIOH1BG module be installed in a standard I/O rack without additional modifications?
A1: Yes, it is designed to plug into the Mark VIe I/O rack and backplane system. However, you must ensure that the rack environment (power bus, wiring, ventilation, terminal boards) meets the module’s requirements.
Q2: Does the module support hot-swapping?
A2: The module supports maintenance‑friendly replacement, but hot‑swapping while the system is live depends on the specific control system configuration and safety protocols. Always refer to your system’s maintenance guidelines.
Q3: Are the input and output channels electrically isolated?
A3: Yes. The module is specified to provide isolation between input channels, between output channels, and between channels and the ground/backplane, which helps prevent noise and fault propagation.
Q4: Can it be used in hazardous (explosive gas) areas?
A4: Yes. The module is certified for use in hazardous areas when installed according to the applicable standards and with approved terminal boards and wiring practices.
Q5: What environmental temperature range does the module support?
A5: The specified operating range is approximately from –30 °C to +65 °C, making it suitable for many industrial settings, including outdoor or poorly‑conditioned cabinets.
Q6: How do I diagnose a failed channel or module fault?
A6: Use the front‑panel status indicators (LEDs) for power, network link, attention/faults. In addition, use the diagnostics tools available in the Mark VIe system or the host control system to read error codes and isolate the fault.
Q7: Which network communication interface does the module use?
A7: It uses dual RJ‑45 Ethernet ports for IONet or Ethernet network communications. The dual ports support redundancy, improving system reliability.
Q8: What is the maximum current for each output channel?
A8: Typically each output channel can handle up to approximately 1.0 A, but actual permissible load may depend on terminal board and system wiring.
Q9: If I need more outputs, can I use a non‑combined input/output module instead of this one?
A9: Yes, but you’ll need to ensure compatibility with the rack configuration and backplane. Using separate dedicated input or output modules may increase footprint or wiring complexity compared to a combined I/O module.
Q10: What is the expected service life of the module under normal industrial use?
A10: While no module is truly “lifetime guaranteed,” the design is industrial‑grade and intended for many years of service if environmental conditions (temperature, dust, vibration, humidity) are controlled and periodic maintenance is observed.
