🛠️ Key Technical Features

  • Signal Conditioning: The board is densely populated with active and passive circuitry (ICs, resistors, capacitors) to filter noise and accurately scale analog field signals before they are transmitted to the main Mark VI processor.
  • Isolation and Protection: It provides essential electrical isolation between the control circuitry and the field devices, protecting the sensitive electronics from high-voltage transients.3 The inclusion of on-board fuses offers circuit protection.4
  • Configurability: The presence of jumpers allows field technicians to configure specific I/O channels, such as selecting between voltage and current input ranges, tailoring the board’s behavior to the specific field sensor or application.
  • Relay Outputs: The board includes relays (discrete outputs) for switching external loads, alarms, or control elements.

⚠️ Important Considerations for Replacement

  • Revision Match is Crucial: The H1A suffix must be matched exactly when replacing the board. Different revisions can have differing signal scaling factors, incompatible firmware, or altered jumper configurations, leading to control failures.
  • Configuration: If the board includes jumpers, the replacement unit must be configured with the exact same jumper settings as the unit being replaced to ensure correct operation.
