Features:
- Conditions 24 contact inputs for Mark VIe control logic.
- Uses independent Ethernet paths for controller communication.
- Checks terminal-board identity and contact-excitation health.
IS220PDIAH1B joins a contact-input terminal board directly through its DC-37 underside connector.
The acquisition stage shifts input levels and isolates field contact signals from the low-voltage processor circuitry.
Channel LEDs, pack-status indicators and internal tests separate field-input faults from pack or network conditions.
The General Electric IS220PDIAH1B Mark VIe Discrete Input Pack is listed as Active / Available from OEM. Apter Power provides IS220PDIAH1B quotations, product documentation and system-matching support.

Contact Signal Processing
- Channels: IS220PDIAH1B accepts 24 contact inputs
- Threshold: A variable comparator follows the wetting-voltage reference
- Isolation: Optocouplers separate inputs from control logic
- Filtering: Each channel includes filtering and hysteresis
Built-in Condition Checks
- Startup: Memory, flash and Ethernet hardware are tested
- Excitation: Loss of contact-wetting voltage is monitored
- Channel Test: Non-responding inputs are detected by threshold pulsing
- Identity: Hardware IDs verify the connected board set
Pack Interface Arrangement
- ENET1: Primary I/O Ethernet interface
- ENET2: Secondary or redundant Ethernet interface
- Power: Three-pin connector accepts the pack supply
- Field I/O: DC-37 couples IS220PDIAH1B to the terminal board
Control Path Options
- Simplex: One pack can use one or two network links
- Dual: Two packs participate in the input path
- TMR: Three packs operate with one network link each
- Signal Logic: Inputs can be inverted and SOE recording enabled in configuration
