Product function

GE IS230TNDSH2A PDIO Terminal Board Provides a rugged, high-density termination point for mixed discrete I/O signals, translating field-wired contacts and loads into conditioned, isolated channels for the PDIO I/O pack. It centralizes wiring, ensures signal integrity through galvanic isolation and overvoltage protection, and interfaces directly to the IONet Ethernet bus via the I/O pack.

Core supporting modules

Discrete I/O Pack: IS220PDIOH1A (simplex) or IS220PDIOH1B (redundant)

Controller: Mark VIe CPU modules (e.g., IS200TPROH1C series)

Safety & Logic: Mark VIeS safety processors where PDIO feeds safety interlocks

Extension components

Terminal Blocks: Screw-clamp pluggable blocks keyed to prevent mis-insertion

DIN-Rail/Pedal-Mount Clips: Adapter kits for 35 mm DIN-rail or panel mounting

Shielding Accessories: Cable-shield clamps and ferrite beads for EMI suppression

Spare Relays & Maintenance Kits: Replacement relay cartridges and terminal-block kits

Software support

Configuration & Calibration: None on the board—channels are defined by pack firmware

Diagnostics: Input status, relay operation, and error counters reported via controller diagnostics and HMI alarms

Integration: Transparent to GE ControlST™/ToolboxST™ engineering tools and Mark VIeS application software

Firmware Updates: Delivered as part of I/O pack firmware via ToolboxST™

Documentation: Detailed in the GE Mark VIe/VIeS I/O Installation Guide and PDIO Pack Reference Manual
