Features:
- Brings voltage, current-loop, and analog command channels together in one distributed I/O pack.
- Works through an approved terminal board so field wiring remains separated from the replaceable electronics.
- Provides a defined replacement boundary for mixed analog loops in turbine and industrial control cabinets.
The channel arrangement helps a service team group related process signals while still respecting the different ranges assigned to the first eight inputs and the final two inputs.
Terminal-board selection is part of the hardware identity. A replacement check therefore includes both the I/O pack label and the board that carries the field connections.
When the surrounding enclosure and power path meet the certified conditions, the module can be integrated into the distributed Mark VIe architecture without changing the basic field-loop concept.
Apter Power can assist with quotation, exact-model review, and sourcing for the General Electric IS220PAICH1B Mark VIe analog I/O module with ten inputs and two outputs.

Channel ranges used by IS220PAICH1B
- Inputs 1–8: Accept -10 to +10 V dc or 0 to 20 mA dc within the certified assembly.
- Inputs 9–10: Cover -5 to +5 V dc or -1 to 20 mA dc.
- Analog command voltage: The output path is listed for 0 to 16.3 V dc.
- Analog command current: The corresponding current range is 0 to 20 mA dc.
- Transmitter feed: The field supply is rated at 24 V dc and 21 mA.
- Configuration check: The physical loop and software range must describe the same signal before commissioning.
Approved hardware relationships for IS220PAICH1B
- Compact terminal option: STAIH1A and STAIH2A families are listed with this analog I/O pack.
- Barrier-style option: The TBAIH1C family is also identified as compatible.
- RoHS construction: IS400BPAIH1A or IS400BPAIH2A may form the internal acquisition assembly.
- Field-side match: RoHS terminal constructions include the corresponding IS400 STAI and TBAI boards.
- Replacement rule: Read the full terminal-board code instead of assuming every PAIC installation uses the same landing hardware.
Certified installation conditions for IS220PAICH1B
- Power window: Supply the module with 24–28 V dc and provide for a maximum input of 0.49 A.
- Enclosure: Classified-location use requires a suitable enclosure providing at least IP54 protection.
- Pollution environment: The installed location must not exceed Pollution Degree 2.
- Transient control: Protection must keep supply transients within 140% of the peak rated voltage.
- Power distribution: Use the certified distribution and switched-mode supply arrangement required for the applicable location.
Commissioning checks for IS220PAICH1B
- Before energizing: Compare the pack, terminal-board, and cabinet wiring designations with the control project.
- Input verification: Apply a test value that stays inside the range assigned to the channel group being checked.
- Transmitter loops: Confirm the 24 V dc field supply and load path before treating a zero reading as an I/O-pack fault.
- Output verification: Check polarity and receiving-device loading before issuing a controlled analog command.
- Return to service: Restore loops one group at a time and confirm the engineering-unit response at the controller.
