Description
The GE General Electric IS220PDIIH1B is a Mark VIe Discrete Input I/O Pack designed to interface discrete field signals with the GE Mark VIe distributed control system. Mark VIe I/O packs include a local processor, dual IONet communication ports, and support system-level diagnostics and sequence-of-events functionality. The IS220PDIIH1B is intended for discrete input applications and should be matched with the appropriate terminal board, I/O configuration, and system revision before installation. GE documentation describes Mark VIe discrete input modules in 24-channel configurations with group or point isolation depending on the terminal-board/module combination.

⚙️ Main Functions
• Receives discrete field signals and transfers input data to the Mark VIe controller through the IONet network.
• Provides local processing for the connected I/O assembly.
• Supports Mark VIe sequence-of-events functionality for time-stamped discrete events.
• Integrates with Mark VIe terminal boards and field wiring assemblies.
• Supports distributed I/O installation, allowing I/O assemblies to be located close to field devices.
• Provides status and diagnostic information through the Mark VIe I/O architecture.
• Can be used within simplex, dual, or TMR Mark VIe configurations when the associated hardware and configuration support the selected architecture.
❓ Q&A
Q: What is the GE IS220PDIIH1B?
A: It is a GE Mark VIe Discrete Input I/O Pack used to acquire discrete field signals for the Mark VIe control system.
Q: What does the IS220 designation indicate?
A: IS220 identifies the Mark VI/Mark VIe family of Ethernet-connected I/O packs used with compatible terminal boards.
Q: Does the I/O pack communicate through Ethernet?
A: Yes. Mark VIe I/O packs use IONet, a dedicated Ethernet-based I/O network, and the I/O pack architecture includes two IONet ports.
Q: Does Mark VIe support sequence-of-events recording?
A: Yes. GE states that sequence-of-events functionality with 1 ms time stamping is available on Mark VIe discrete I/O.
Q: Is this the same as a discrete output pack?
A: No. The PDII designation identifies a discrete-input function. GE also offers separate discrete-output and combined discrete I/O packs, so the exact model number should be matched before replacement.
Q: Can this pack be installed with any Mark VIe terminal board?
A: No. Terminal-board compatibility is configuration dependent. Verify the terminal-board model, I/O pack revision, wiring, and system configuration before installation.
Q: What should I check before replacement?
A: Check the complete IS220PDIIH1B part number, revision, terminal-board model, IONet configuration, field wiring, and the existing Mark VIe hardware configuration.
