Technical Description & Structure

This board utilizes 12 plug‑in magnetic relays arranged to provide flexible output configurations. The first six relays can be configured for solenoid driving or dry form‑C contact outputs, while the remaining relays serve as isolated contact outputs for a variety of field control functions. It includes on‑board suppression components and barrier terminals to ensure stable signal transmission and protect against electrical noise.

• Relay Channels: 12 total
  • First 6: Configurable solenoid drive or dry contact
  • Next 5: Isolated Form‑C contacts
  • Final: Specialized Form‑C output (e.g., ignition transformer use)
• Signal Terminals: 48 barrier terminals for field wiring
• Connectors: Multiple backplane connectors for integration with I/O packs
• Suppression: MOV and protective components on relay rails
