TRICONEX AO2481 8-Channel Analog Output Module in stock

TRICONEX AO2481 is an 8-channel isolated analog output module for Tricon triple modular redundant safety instrumented system. It outputs 4-20mA analog control signals to field control valves and actuators to adjust temperature, pressure and flow in safety-critical industrial processes.

This module adopts TMR triple voting fault-tolerant architecture with 12-bit high precision and continuous channel self-diagnosis function. It supports online hot swap without shutting down the SIS system, widely used as spare replacement for petrochemical, power and chemical safety control cabinet maintenance and retrofit projects.
