TRICONEX 3502E
Product Description:
The TRICONEX 3502E is a high-integrity triple modular redundancy (TMR) digital input module designed for use in critical safety instrumented systems (SIS) within industries such as oil & gas, power, and chemicals. It provides 32 channels of fault-tolerant digital input processing, supporting 48V AC/DC signals and robust self-testing. The module independently processes each input through three isolated redundant channels, offering continuous operation even if a single channel fails. Advanced diagnostics, high-voltage isolation, and modular expandability ensure reliability, safety, and system flexibility.
