Core Functions

1. 16‑Channel Relay Output Switching: Controls high‑power field devices (motor starters, solenoids, alarms, actuators) via dry‑contact relays.

2. High‑Voltage Isolation: 1500 VAC isolation protects DCS from load‑side electrical noise and voltage spikes.

3. Harsh Environment Protection: Enhanced conformal coating safeguards against dust, moisture, and corrosive gases in harsh areas.

4. CE/UL/RoHS Compliance: Meets global safety and environmental standards for 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.

7. Vibration Resistance: Heavy‑duty screw terminals and 5g vibration rating ensure reliability in high‑vibration environments.

Application Scenarios

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

• High‑Power Device Control: 120 VAC/125 VDC motor starters, solenoid valves, alarm beacons, and heavy‑duty actuators.

• Legacy DCS Systems: Replacement/expansion for Honeywell TDC3000/TPS installations in harsh plant areas.

• Corrosive/High‑Vibration Zones: Outdoor control rooms, manufacturing floors with heavy machinery, and high‑humidity facilities.

• Global Deployments: Facilities requiring CE, UL, and RoHS markings for compliance.
