Core Functions

1. 12‑Channel Digital Output Switching: Controls 24 VDC field devices (solenoids, relay coils, indicators, small actuators) via solid‑state circuits.

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

3. Moderate Environment Protection: Standard conformal coating improves resistance to dust, moisture, and mild corrosives vs basic coating.

4. CE/UL Compliance: Meets European and North American safety standards for wider industrial deployments.

5. Backplane‑Powered: Draws power from UCN backplane, eliminating external power supplies.

6. Status Monitoring: Individual channel LEDs enable quick visual status checks for maintenance.

Application Scenarios

• Process Industries: Chemical, petrochemical, power generation, pulp & paper (general/moderate non‑corrosive environments).

• Low‑Voltage Device Control: 24 VDC solenoid valves, relay coils, LED indicators, and small‑scale actuators.

• Legacy DCS Systems: Replacement/expansion for Honeywell TDC3000/TPS needing CE/UL compliance.

• Indoor/Protected Zones: Control rooms, dry manufacturing floors, and low‑humidity facilities.

• Global Deployments: Projects requiring CE marking for European market access.

51304446 Series Key Differences

Compatibility Note

• Form‑factor compatible with other 51304446 series (Size C, UCN connector).

• Functionally compatible with 51304441 series (digital output, UCN protocol).

• Recommended for legacy TDC3000/TPS systems needing 24 VDC non‑isolated digital outputs in moderate environments with CE/UL compliance.
