5. Function Overview

• Acquires 32-channel 24VDC discrete signals from field switches, relays, and sensors

• Three TMR channels sample signals independently; 2oo3 voting ensures data validity

• Diagnostics continuously monitor for faults and report to TriStation

• Supports SOE for time-stamped event analysis

• Integrates with Trident main processors (e.g., 2101) for safety logic execution

6. LED Indicators

• PWR (Green): 5VDC backplane power OK

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

• FAULT (Red): Channel/module fault or voting mismatch

• CH (Yellow): Per-channel input status (ON/OFF)

7. Installation & Configuration

1. Insert 2700 into an empty Trident baseplate slot

2. Connect 24VDC field discrete signals to the terminal base

3. Use TriStation 1131 to set sink/source, fault thresholds, and SOE enable

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

8. Typical Applications

• ESD emergency shutdown system discrete signal monitoring

• BMS burner management system flame switch/valve position input

• Safety interlock limit switches, pressure switches, and level switches

• Fire & gas system detector status inputs

• Power plant turbine/generator safety sensor monitoring

9. Maintenance
