Triconex 3700 Analog Input Module in stock

Triconex 3700 is a 32-channel differential analog input module for Triconex Tricon TMR safety instrumented system(SIS). It receives 0-5VDC analog signals from pressure, temperature and flow transmitters, converts analog signals to digital data and sends to triple redundant main processors for safety voting calculation.

This module adopts triple modular redundancy architecture with continuous per-channel diagnostics. It supports hot-swap replacement without shutting down the safety system, widely used for ESD, FGS safety cabinet maintenance, spare parts replacement and safety interlock system retrofit projects.

FAQ

• 1. Q: What is Triconex 3700?
      A: It is a 32-channel differential analog input module for Triconex Tricon SIS safety system for collecting 0-5VDC sensor signals.

• 2. Q: What is TMR architecture?
      A: Triple Modular Redundancy, three independent signal paths perform voting, the system still works with single path fault.

• 3. Q: Can 3700 be hot swapped?
      A: Yes, it supports hot swap, module replacement will not shut down the whole Tricon safety system.
