Materials & Construction:
-
Housing: Galvanized steel shell with powder coating
-
PCB: 6-layer FR-4 with conformal coating
-
Connectors: Mil-D-38999 circular (bus side) / D-Sub (signal side)
-
Terminal block: Phoenix terminals, nickel-plated
Structural Features: Standard Mark V/VI cabinet mounting dimensions; front-panel channel-status LEDs (one group per 4 channels); rear SRTP bus connector plus signal terminal strip; top positioning rail clip.
Working Principle: The module communicates with the Mark V/VI controller (CPU module) over the SRTP high-speed redundant bus, converting between field-level analog/digital signals and the controller’s internal data representation.
Installation & Usage Notes: Install inside a control cabinet; ensure proper grounding of the cabinet. Verify jumper settings against the existing module before replacement. Because this is a redundant, hot-swappable module, observe ESD precautions and confirm the system is in a safe state before removal.
