Features:
- Supported boards: official documentation identifies TDBSH2A and TDBTH2A.
- Field role: the terminal-board selection defines the installed discrete I/O arrangement.
- Connector check: inspect latches, pins and seating before power-up.
IS220PDIOH1A is the PDIO discrete input/output I/O pack in GE’s Mark VIe control platform.
A correct IS220PDIOH1A service match considers the terminal-board type, connector seating, 28 VDC power and installed control configuration together.
For IS220PDIOH1A replacement, Apter Power recommends recording the existing pack and terminal-board labels, then using Mark VIe diagnostics to verify communications and every affected point.
Apter Power supports documentation review, procurement planning and quotation for General Electric model IS220PDIOH1A, a Mark VIe PDIO Discrete Input/Output I/O Pack.
