P0924AU

P0924AU is a TRICONEX Tricon Triple-Modular Redundant (TMR) Safety Digital Input Module (also known as TRICONEX P0924AU High-Integrity Safety I/O Module), a core safety-critical input component designed exclusively for TRICONEX TMR safety programmable logic controller (PLC) systems.

The P0924AU module is an industrial-grade safety digital input module developed by TRICONEX (a Schneider Electric brand and global leader in industrial safety automation). It is engineered to deliver high reliability, fault tolerance, and real-time performance for safety-critical applications in process industries. As a key part of the TRICON TMR safety PLC system, its primary function is to collect digital signals from field safety devices—such as emergency stop buttons, safety interlock switches, fire/gas detectors, and door position sensors—ensuring accurate and secure transmission of safety-related status data to the TMR controller.

Adopting triple-modular redundant (TMR) architecture, the module eliminates single points of failure, meeting the most stringent safety standards including SIL 3 (IEC 61508) and PLe (ISO 13849-1). This makes it ideal for protecting personnel, equipment, and processes in high-risk environments. The module features a rugged industrial design with enhanced electromagnetic interference (EMI) resistance, wide temperature tolerance, and resistance to vibration and dust, enabling stable operation in harsh industrial conditions such as oil refineries, chemical plants, and power stations.

Seamlessly integrating with TRICONEX Tricon 1000/2000/3000/4000 series safety PLC systems, the P0924AU module supports critical safety functions including emergency shutdown (ESD), process interlocking, fire and gas (F&G) protection, and machine safety control. It is widely used in oil and gas, petrochemical, chemical processing, power generation, and pharmaceutical industries where uncompromised safety and reliability are non-negotiable.
