  • Connector: UCN 96‑pin edge connector (gold‑plated contacts, enhanced for high‑channel count)

Core Functions

  1. 52‑Channel High‑Density Digital Output Switching: Controls 24 VDC field devices (solenoids, relay coils, indicators, small actuators) in large‑scale process plants.

  2. Basic Electrical Isolation: 500 VAC channel‑to‑backplane isolation protects DCS from load‑side noise (non‑isolated between channels).

  3. Harsh Environment Protection: Enhanced conformal coating provides maximum resistance to dust, moisture, corrosives, and extreme temperatures.

  4. Global Compliance: CE/UL/RoHS certified for worldwide industrial deployments (Europe, North America, Asia).

  5. Backplane‑Powered: Draws power from UCN backplane, eliminating external power supplies for high‑density I/O.

  6. Status Monitoring: Individual channel LEDs enable quick visual status checks for maintenance of large I/O banks.

Application Scenarios

  • Process Industries: Heavy chemical, petrochemical, power generation, pulp & paper (harsh/corrosive environments).

  • High‑Density Device Control: Large arrays of 24 VDC solenoid valves, relay coils, LED indicators, and small‑scale actuators.

  • Legacy DCS Systems: Replacement/expansion for Honeywell TDC3000/TPS needing high‑channel count and global compliance.

  • Harsh/Outdoor Zones: Uncontrolled plant areas, high‑humidity facilities, and corrosive process zones.

  • Global Deployments: Projects requiring CE/UL/RoHS marking for European, North American, and Asian market access.
