GE IS220PDIOH1B Mark‑VIe Digital Input‑Output Board (Revised Version)

Technical Specifications Signal: Multi‑channel discrete input‑output Bus: Mark‑VIe I/O backplane Operating Temperature:‑30℃ ~ +70℃ Mounting: I/O rack plug‑in module

Functional Features Discrete signal sampling and driving output Enhanced on‑channel surge protection Channel fault self‑diagnosis

Application Scenarios Mark‑VIe distributed I/O cabinet, updated hardware configuration

Performance Parameters Improved channel anti‑surge capability Consistent signal response timing with predecessor model

Structural Characteristics Revised compact PCB assembly I/O backplane connector Front‑panel channel LED status indicators Module locking latch

Working Principle Same I/O logic as IS220PDIOH1A, processes field switch‑value signals and exchanges data with Mark‑VIe main controller over I/O backplane bus.

Installation Requirements Verify hardware & firmware compatibility with existing rack. Execute ESD anti‑static procedures.

Usage Notes Direct replacement allowed only under compatible system revision
