Process Instrumentation and Loop Configuration Versatility
The C1900 coordinates real-time signal acquisition and multi-variable logging on a single circular chart baseline. To support flexible process layouts without requiring external auxiliary hardware devices, the instrument allows its two onboard PID control loops to operate completely independently or be soft-linked together via internal configuration matrices. This soft-linking capability enables engineers to implement cascade control architectures directly within the device. The localized logic engine supports user-configurable math functions, mass flow calculations, totalizers, and relative humidity (RH) tables, passing all derived values to the active recording pens or the RS485 MODBUS network registers simultaneously.
