The IS220PDIAH1A (and IS220PDIAH1AD) is a 24‑channel discrete input I/O pack for GE Mark VIe turbine control systems. The IS220PDIAH1A converts field dry contact signals from switches, relays, and pushbuttons into digital status data, transmitting it over dual redundant IONet Ethernet ports. Built with optical isolation, a 4 ms hardware filter, and a local processor for independent signal conditioning, the IS220PDIAH1A mounts directly onto compatible terminal boards (TBCIH1, TICI, STCI) and operates from –40 °C to +70 °C in harsh industrial environments.
Gas/steam turbine discrete signal acquisition (valve limits, pushbuttons, relays)
IONet‑based distributed control system I/O expansion
Interlock logic and alarm monitoring for Mark VIe platforms
Retrofit and replacement of legacy discrete input modules
24 optically isolated inputs (1500 V): Blocks EMI and protects controller electronics.
Dual redundant 10/100 Ethernet ports: Seamless IONet failover.
4 ms hardware input filter: Removes contact bounce without software delay.
Multiple voltage compatibility: Works with 24/48/125 VDC terminal boards (TBCIH1/H2/H3, TICI, STCI).
Local processor with acquisition board: Offloads filtering from main controller.
Hazardous location certified: UL Class I Div 2, ATEX Zone 2.
Infrared serial port: Hand‑held diagnostic access.
Conformal coated PCB: Resists moisture and dust.
Soft‑start power input: Limits inrush current at power‑up.
Scans 24 dry contact inputs, optically isolates each channel, and transmits state data to the Mark VIe controller via dual‑redundant IONet Ethernet.
Applies 4 ms hardware debounce to reject contact bounce and electrical noise, delivering clean digital status to the CPU.
Provides 32 VDC contact wetting output for dry contacts, eliminating external excitation supplies.
Performs continuous self‑diagnostics (memory, Ethernet, power, acquisition board) and reports faults via LED and controller fault table.
Supports simplex, dual, or TMR redundancy architectures based on number of I/O packs installed.
Q1: What is the IS220PDIAH1A ?
A1: A 24‑channel discrete input I/O pack for GE Mark VIe, converting field dry contacts into digital data over redundant Ethernet.
Q2: What voltage levels does it support?
A2: Nominal 24 VDC, but with TBCIH2/H3 or TICI boards it accepts 48 VDC or 125 VDC.
Q3: How many Ethernet ports does it have?
A3: Two independent 10/100 ports for redundant IONet communication.
Q4: Is it compatible with DTCI terminal board?
A4: No. It works with TBCIH1/H2/H3, TICI, and STCI boards only.
Q5: What is the difference between IS220PDIAH1A and IS220PDIAH1AD ?
A5: Electrically identical. The “D” suffix is an alternate part number for supply chain compatibility.
