Technical Specifications Signal Channel: Multi‑channel discrete signal Connection: System backplane bus Operating Temperature:‑20℃ ~ +70℃ Function: Support hot‑swap operation
Functional Features Hardware filtering for field input signals High‑speed digital signal acquisition Hot‑swap during system running High‑speed backplane bus data transmission
Application Scenarios Factory automation discrete signal acquisition PLC digital input‑output control loops
Performance Parameters Fast signal response speed Built‑in channel fault diagnosis Resist industrial cabinet mechanical vibration
Structural Characteristics Standard rack plug‑in module Front‑side field signal terminal block Front‑panel channel status LED indicators Backplane golden‑finger bus connector
Working Principle Collects field switch signals via front terminals, filters interference noise and transmits data to PLC CPU through backplane bus. Converts controller commands into switch output signals for field actuators.
Installation Requirements Plug into matched PLC system rack slot. Tighten terminal connection screws. Observe ESD anti‑static operation rules.
Usage Notes Signal input voltage shall conform to module rated range. Check LED status indicators regularly during operation.
