Core Functions

1. Relay Output Switching: 16 independent SPDT relays for on/off control of field loads (valves, pumps, solenoids).

2. Field Termination: Centralizes digital output wiring from DCS IOPs to field devices via screw terminals.

3. Electrical Isolation: Protects DCS from field‑side voltage spikes, noise, and ground loops.

4. Status Monitoring: Per‑channel LEDs for instant visual verification of output state.

5. Cost‑Effective Operation: Uncoated, non‑certified design reduces cost for standard industrial environments.

Application Scenarios

• Process Industries: Chemical, petrochemical, oil & gas, power generation, pulp & paper (non‑harsh areas).

• Field Device Control: On/off control of valves, pumps, fans, motors, and solenoids (≤5 A).

• Alarm Systems: Driving audible/visual alarms for process events.

• Interlock Circuits: Non‑safety interlocks (non‑SIL rated) for process control.

• Standard Environments: Ideal for clean, dry industrial areas (no conformal coating needed).

Key Differences: 51304427-200 vs 51304427-100/150

Compatibility Note

• Fully pin‑compatible with 51304427-100/150; direct drop‑in replacement for TDC3000/TPS UCN racks.

• Recommended for new installations in standard environments (lowest cost option).
