Official Specification & User Manual (English)

1. General Description

2. Part Number & Type

• Model: 2402

• Type: Digital Output Baseplate (DO), TMR

• Series: Trident (Triconex / Schneider Electric)

• Safety Level: SIL 3 (IEC 61508)

• Approvals: TÜV Rheinland, FM, CSA

3. Key Features

• 16 Isolated Digital Output Channels

  Supports 24–125 VDC field devices (solenoids, relays, alarms).

• Triple Modular Redundancy (TMR)

  2oo3 voting; three independent output paths per channel.

• High Voltage Isolation

  2500 V RMS channel‑to‑backplane isolation.

• Per‑Channel Current Limiting

  Protects against short circuits and overloads.

• Voltage Loopback Diagnostics

  Detects open load, missing field power, and wiring faults.

• Hot‑Swappable

  Replace upper DO module online without shutdown.

• Dual Field Power Inputs

  PS1 / PS2 for redundant 24–125 VDC field power.

5. Functional Overview

• Field Power Distribution

  Distributes redundant 24–125 VDC (PS1/PS2) to 16 channels.

• TMR Output Drive

  Works with DO module to provide 2oo3‑voted on/off commands.

• Diagnostics & Alarms

  Voltage loopback checks detect open load, short circuit, missing field power; reported via TriStation.

• SOE Logging

  Time‑stamps state changes and faults (≤ 40 ms).

6. LED Indicators (on mating DO module)

• PWR (Green): Module power OK

• RUN (Green): Active, communicating

• FAULT (Red): Channel/module fault

• CH 1–16 (Yellow): Channel ON

7. Installation & Configuration

1. Mount 2402 in Trident chassis slot.

2. Plug compatible DO module (e.g., 2401) onto 2402.

3. Connect 24–125 VDC field power to PS1/PS2 terminals.

4. Wire field devices (solenoids, relays) to 16‑channel terminal block.

5. Use TriStation 1131 to:

   • Set fail‑safe state

   • Enable voltage loopback diagnostics

   • Configure fault thresholds

6. Verify: PWR + RUN green, no FAULT red.

8. Typical Applications

• ESD solenoid valves (24–125 VDC)

• BMS fuel shutoff valves

• Safety relay coils

• Fire & gas alarm beacons/horns

• HIPPS auxiliary relays

9. Maintenance

• Hot‑swap DO module; baseplate is non‑swappable.

• Inspect PS1/PS2 field power and wiring.

• Review SOE and fault logs via TriStation.
