191xxseeria
191xxseeria is a designation used to describe a family of modular industrial automation devices intended for distributed control and sensing tasks. The series is characterized by its modular hardware architecture, where different input/output (I/O) and communication modules can be combined to form a compact controller network. The name combines the numeric 191xx prefix, suggesting generation and variant coding, with seeria, a term used in catalogs to denote a product line.
Historical context: The 191xxseeria was introduced in the late 1990s as a bridge between traditional fixed-function
Design and features: The devices are built around a modular chassis hosting fieldbus interface modules, digital
Variants and coding: The 191xxseeria uses a naming scheme where the trailing digits indicate I/O count and
Applications: Widely used in manufacturing, packaging, water treatment, building automation, and process control where compact, scalable
