• Max Frequency: 10Hz (inductive loads)

4.2 Pulse Input (PI) Mode

• Number of Channels: 8

• Input Type: 24VDC binary, dry contact, pulse (0–10kHz)

• Input Voltage: 24VDC ±20%

• Isolation: 1500VAC channel‑to‑backplane

4.3 Redundancy & Safety

4.5 Power & Physical

• Backplane Power: 5VDC

• Power Consumption: ≤2.5W

• Dimensions: 150mm × 130mm × 35mm

• Weight: ~0.5kg

5. Function Overview

• DO Mode: Drives solenoid valves, motor starters, alarms, and ESD trip relays; feedback monitors relay status

• PI Mode: Counts pulses from flow meters, speed sensors, and incremental encoders; 1ms SOE timestamps

• TMR compatibility ensures 2oo3 voting for safety logic

• Integrates with Trident CPU (2750) and analog modules (2755)

6. LED Indicators

• PWR (Green): 5VDC backplane power OK

• RUN (Green): Module active, TMR sync normal

• FAULT (Red): Channel fault, voting mismatch, or relay feedback error

• CH1–8 (Yellow): Per‑channel status (ON/OFF or pulse activity)

7. Installation & Configuration

1. Insert 3002 into Trident baseplate half‑size slot

2. Wire field devices (valves, meters) to FTA terminal block

3. Use TriStation 1131 to set mode (DO/PI), channel logic, and diagnostics

4. Verify: PWR+RUN green; no FAULT red; CH LEDs reflect activity

8. Typical Applications

• ESD: Solenoid valve control, trip relay actuation

• BMS: Fuel gas valve control, flame alarm outputs

• FGS: Gas detector alarm outputs, deluge valve control

• Turbine: Speed pulse input, trip relay output

• Process: Flow meter pulse counting, on/off valve control

9. Maintenance

• Hot‑swap faulty 3002 without downtime

• Check relay contacts for wear (DO mode)

• Verify pulse signal integrity (PI mode)

• Review fault logs via TriStation
