ICS triplex T8403
ICS Triplex T8403 is a highly reliable digital input module designed for critical control systems that require high security and availability. It uses triple module redundancy (TMR) technology to ensure stable system operation even under extreme conditions. The module is widely used in the safety instrumentation system (SIS) of electric power, petrochemical, chemical and other industries.
Main function
Digital input: Receive signals from various digital sensors, switches and other devices, such as limit switches, pressure switches, etc.
Triple Module redundancy (TMR): Three identical hardware modules are used for redundant backup by voting to improve system reliability.
Fault detection: It can detect the fault inside the module in real time and send an alarm signal.
Self-diagnosis: The module has a self-diagnosis function, which can automatically detect its own working status.
