IS200STAIH2A at a Glance

The IS200STAIH2A is a Simplex Analog Input (STAI) terminal board from GE's Mark VIe distributed I/O family. It is the field-wiring side of an analog input node: a compact, DIN-rail-mountable board that terminates 10 analog inputs and 2 analog outputs, and hands them to a PAIC Analog I/O pack that communicates with the controller over Ethernet. Per the Mark VIe documentation (GEH-6721), the ten inputs accept two-wire, three-wire, four-wire, or externally powered transmitters, with voltage inputs of ±5 or ±10 V dc also supported; 24 V dc power for transmitters is available on the board. The two outputs are 0-20 mA current loops, and one of them can be reconfigured by jumper for 0-200 mA service.

Physically, the board measures roughly 15.9 by 10.2 cm, is rated for -30 to +65 °C, and mounts on a sheet-metal carrier for DIN-rail installation or bolts directly into a cabinet. Wiring lands on high-density Euro-block terminals — on the H2 version, pluggable terminal blocks seated on a right-angle header, which makes board changeouts faster because the field wiring stays on its plugs. An on-board ID chip reports the board type, serial number, and revision to the mating pack for system diagnostics.

Terminal Board or I/O Pack? Isolate Before You Order

The STAI is passive termination plus burden resistors and jumpers; the intelligence — multiplexer, A/D conversion, Ethernet — lives in the PAIC pack seated on it. That split tells you how to troubleshoot:

• Every channel bad at once almost always means the pack, its power feed, or its Ethernet link — not the terminal board. Check the PAIC's status LEDs and network connectivity first.
• One dead 4-20 mA input: verify the transmitter and its loop power (the board offers 24 V dc), then check the channel's input-type jumper. The current-loop burden resistor sits on the terminal board, so a single channel that stays dead after you have proven the transmitter — ideally by landing it on a spare channel — is fair evidence against the STAI.
• A "hardware incompatibility" diagnostic means the pack read the board's ID chip and found a mismatch with its configuration — wrong board group or revision for what the system expects. That is a configuration or matching problem, not necessarily a failed board.
• Noisy or drifting readings point to wiring practice: shielded twisted pair (18 AWG is typical), the shield landed on the board's shield terminal, and total two-way lead resistance within the documented 15-ohm limit.

What H2A and the BA Revision Mean

The full number on this unit is IS200STAIH2ABA: IS200 platform prefix, STAI function code, H2A group, BA revision. Within the STAI family the group letter-digit combination distinguishes the terminal hardware — GE's documentation describes the -1 style with a permanently mounted 48-point terminal block and the -2 style with pluggable terminal blocks on a right-angle header. Match the group code on your existing board so your wiring approach carries over unchanged. The final two letters, BA here, are the revision; supply the complete string from your label when ordering and we will confirm compatibility. Our GE Speedtronic Part Number Decoder covers the numbering system across GE families.

Simplex by Design: STAI vs TBAI

The STAI carries a single pack connection, which is exactly why GE labels it simplex: there is no way to attach the three redundant packs that a TMR I/O node requires. In protection-critical loops where Mark VIe runs triple-redundant I/O across the <R>, <S>, and <T> channels, the TBAI terminal board architecture is used instead. If you are unsure which architecture your channel uses, count the packs on the terminal board — one pack means STAI-class simplex termination like this board.

Information That Makes Your RFQ Move Faster

• Complete part number with revision: IS200STAIH2ABA (a board-label photo settles group and revision instantly).
• The mating I/O pack part number from your node (a PAIC variant), so we can sanity-check the pairing.
• Your control system and site context — Mark VIe, including Mark VIe retrofits on older Speedtronic plants.
• Quantity, condition preference, and urgency — forced outage requests get same-day attention.
• Delivery country and site for the DDP calculation.
