Description

Triconex 3626X

Technical Specifications:

  • Type: Supervised digital output module
  • Channels: 32 points (commoned)
  • Nominal Voltage: 24 VDC typical
  • Current Rating: Per-point rating (consult datasheet; supports typical industrial loads)
  • Diagnostic Coverage: High per-point diagnostic coverage
  • Operating Temperature: 40 °C to +70 °C
  • Mounting: Tricon chassis slot with hot-swap capability

Functional Features:

  • Per-point diagnostics for open/short and stuck conditions
  • Supervised outputs with feedback circuits for fault detection
  • Module status LEDs and per-point indicators
  • Supports TMR voting and redundant operation

Application Scenarios:

  • ESD final element actuation (solenoid valves, shutdown devices)
  • Fire and gas system outputs (horns, strobes, suppressions)
  • Safety interlocks and permissive outputs in process plants

Performance Parameters:

  • Fast response times for safety actions
  • High diagnostic coverage for output faults

Material and Structural Characteristics:

  • Industrial PCB with protection and diagnostic circuits
  • Tricon front panel with keyed connector and LEDs

Working Principle: Each output is driven and monitored for correct operation. Diagnostic circuitry detects open-circuit, short-circuit, and stuck-on/off faults and reports them. In TMR configurations, outputs are voted across redundant modules for higher availability. Installation Requirements:

  • Install into Tricon I/O chassis; verify correct orientation
  • Connect field wiring via external termination assemblies; observe current ratings
  • Configure supervision parameters via TriStation
  • Test each output path during commissioning

Usage Notes:

  • Do not exceed per-point current and total module current ratings
  • Use external relays for high-current inductive loads and include suppression
  • Regularly check diagnostic alarms; replace faulty modules online
