The Fixed-Terminal Variant: IS200STAIH1A

Not every analog input node needs pluggable terminal blocks. The IS200STAIH1A is the STAI variant that GE's Mark VIe terminal board documentation describes with a permanently mounted 48-point Euro-block — field wiring screws directly to the board rather than to removable plugs. Everything else about it is classic STAI: a compact Simplex Analog Input terminal board that terminates 10 analog inputs and 2 analog outputs and mates with a PAIC Analog I/O pack, which digitizes the signals and carries them to the Mark VIe controller over Ethernet.

The input channels are flexible by jumper configuration: two-wire, three-wire, and four-wire transmitters, externally powered transmitters, or ±5/±10 V dc voltage signals, with 24 V dc transmitter power available at the board. The two output loops are 0-20 mA, one of them jumper-selectable for 0-200 mA duty. The board mounts on a DIN-rail carrier with an insulator (or bolts to a cabinet panel), runs from -30 to +65 °C, and identifies itself to the mating pack through an on-board ID chip that encodes board type, serial number, and revision.

Field Checks That Save an Unnecessary Board Swap

Because the STAI holds no processor, most "terminal board failures" trace back to the loop or the pack. Work in this order:

• Prove the transmitter. Measure loop current at the terminals. A dead transmitter, a lost 24 V dc feed, or an open field cable produces the same dead channel a failed board would.
• Check the jumpers. Each channel's current-versus-voltage selection (jumpers J1A–J8A on the first eight channels) and return configuration (J1B–J8B) must match the loop design. A board swapped in with factory-default jumpers will misread perfectly healthy loops — worth remembering both when diagnosing and when installing the replacement.
• Move the loop to a spare channel. If the signal follows the transmitter to the new channel, the original channel's termination — including its on-board burden resistor — is suspect, and the STAI becomes the probable fault.
• Look at the whole node. If all ten inputs fail together, or the node drops offline, the PAIC pack, its power, or its network link is the likelier culprit; the passive STAI rarely takes down every channel simultaneously.

H1A vs H2A: Two Terminal Block Styles

Decoding IS200STAIH1ABB: IS200 is the platform prefix, STAI the function code, H1A the group, and BB the revision letters. The practical difference inside the family is the wiring interface — the -1 style carries the fixed 48-terminal block found on this board, while the -2 style accepts pluggable terminal blocks. Both terminate the same 10-input, 2-output complement, but they are not drop-in equals from an installation standpoint: your panel's wiring approach was built around one style. Match the group code from your existing board's label, and quote the full string including revision. The GE Speedtronic Part Number Decoder explains how these segments work across GE board families.

Where STAI Sits in the Mark VIe I/O Architecture

Mark VIe distributed I/O splits every node into a terminal board (wiring, burden resistors, jumpers, ID chip) and an I/O pack (acquisition electronics and dual Ethernet). The STAI is the simplex terminal board for analog inputs — one pack, one channel of control. TMR-critical loops instead use TBAI-class boards that host redundant packs on the <R>, <S>, and <T> networks. This architecture is the evolutionary successor to the cabled VME I/O of Mark VI and the DS200-era boards before it — if you are tracing a plant's control lineage while planning spares, our guide Mark V vs Mark VI: DS200 to IS200 maps how GE's part numbering and packaging changed across generations. Note that although this board is catalogued under Mark VI IS200 (see the table below — a common convention driven by the shared prefix), its documented home is the Mark VIe I/O system, including Mark VIe upgrades installed at former Mark VI sites.
