Key FeaturesVOGI
High-density input architecture: Triconex 4351B adopts a high-density input architecture, which can realize the interconnection between multiple digital input signals in a narrow area. In view of the need for a large number of signal inputs in industrial sites, this module can be applied to digital logic signals such as switch status and sensor signals.
Reliability and durability: As a member of the Triconex series of products, it inherits the above-mentioned high reliability and durability characteristics. It is suitable for application scenarios that require long-term all-weather operation in industrial environments, with system stability guarantee and reduced system maintenance costs.
Multiple communication interfaces: Triconex 4351B communicates with control systems or other entities with the help of multiple communication interfaces such as Ethernet (802.3), RS-232, RS-485, etc. This allows high-quality data exchange between devices because it can relay input data to the monitoring system or controller.
Excellent safety management performance: Since Triconex 4351B module is used more for safety, it has more safety features, such as redundant self-test inputs, which can provide sufficient safety and reliability in key application areas and effectively avoid accidents.
