1. Product Introduction

2. Technical Specifications

• Channels: 16 independent isolated digital outputs (sourcing/sinking)

• Output Type: 24 VDC logic, 0.5 A per channel (max 2 A total)

• Isolation Voltage:

  • Channel to backplane: 1500 VAC, 1 minute

  • Channel to channel: 500 VAC, 1 minute

• Load Voltage Range: 18–30 VDC (nominal 24 VDC)

• Response Time: ≤ 8 ms (typical)

• Power Supply: 24 VDC ±10% (from DCS backplane)

• Max Power Consumption: ≤ 5 W

• Operating Temperature: 0 °C to +55 °C

• Storage Temperature: −20 °C to +70 °C

• Relative Humidity: 5%–95%, non‑condensing

• Key Features: Hot‑swappable; fail‑safe (OFF) on power/communication loss

• LED Indicators: Green (PWR), Red (FAULT), Yellow (CH1–CH16 status)

• Physical: Single‑slot module; approx. 220 × 30 × 250 mm, 1.2 kg

3. Application Fields

• Power Generation: Thermal/nuclear power plant valve control, pump motor start/stop, interlock relay driving.

• Petrochemical: Solenoid valves, emergency shutdown (ESD) devices, motor starter coils.

• Water Treatment: Dosing pumps, drain valves, aeration equipment control.

• General Process Industries: Metallurgy, pulp & paper, cement, and other high‑reliability discrete output applications.

4. Installation & Wiring

1. Pre‑installation: Ensure the DCS cabinet is de‑energized before installation.

2. Module Insertion: Insert the module into an available I/O slot; the backplane connector engages automatically.

3. Hot Swap: Verify the system permits online replacement (Ovation/WDPF compatible).

4. Field Wiring:

   • Connect load positive to OUT terminal, load negative to COM terminal per channel.

   • Maintain isolation between field wiring and backplane cabling.

5. Secure Connections: Avoid over‑torqueing terminals; ensure wiring is neat and secure.

5. Operation & Diagnostics

• Power‑on: Green PWR LED illuminates when 24 VDC is supplied.

• Channel Status: Yellow LED = output ON; LED off = output OFF.

• Fault Indication: Red FAULT LED = detected fault (e.g., communication loss, overcurrent, short circuit, or channel failure).

• Diagnostics: The module reports channel‑level status to the DCS for alarm and maintenance logging.

6. Maintenance & Safety

• Preventive Maintenance: Inspect connections annually; test output channels for accuracy and load capacity.

• Safety:

  • Disconnect all power before servicing.

  • Do not exceed rated output voltage/current.

  • Operate within specified temperature/humidity limits.

7. Product Status

• Lifecycle: End‑of‑Life (EOL); original manufacturing discontinued.

• Availability: Refurbished and used units offered as spare parts; typical warranty 6–12 months.

• Compatibility: Fully compatible with Ovation, WDPF, and Q‑Line DCS systems。
