Product Description
The YS1700-030 is a flagship programmable single-loop controller from the Yokogawa Electric Corporation YS1000 controller family, designed for high-availability process regulation in mission-critical industrial environments.
This panel-mount controller is widely used in chemical processing, pharmaceutical manufacturing, and power generation facilities where stable and precise loop control is essential. The YS1700-030 features a dual CPU architecture, separating control processing and display management functions to ensure that manual control remains available even in the event of control processor failure.
The unit is equipped with a 3.5-inch sunlight-readable color TFT LCD, providing operators with clear visualization of trends, alarms, and process variables. The controller supports both function block programming (GUI-based) and text-based logic programming, allowing flexible implementation of cascade, selector, and advanced custom control strategies.

Application and Operational Context
The YS1700-030 is commonly used as a replacement for legacy pneumatic or early-generation electronic controllers. Its high reliability makes it suitable for:
-
Boiler combustion control and drum level regulation
-
Chemical reactor temperature and pressure control
-
Custody transfer flow measurement and totalization
-
Local emergency backup control for DCS systems during network disruptions
The integrated manual backup capability allows operators to maintain safe process operation even during control network outages.
FAQ
How does the dual CPU architecture benefit my process?
If the primary control CPU fails, the YS1700-030 automatically switches to manual backup operation handled by the display CPU. This ensures continuous process stability and prevents sudden shutdowns.
Does this controller require a backup battery?
No. The controller uses non-volatile EEPROM memory to store configuration and control logic, eliminating battery maintenance and improving long-term reliability.
What is the difference between YS1700 and YS1500?
The YS1700-030 is fully programmable and supports custom control algorithms and logic programming. In contrast, the YS1500 series is typically a pre-configured indicating controller with fixed control functions, offering less flexibility for complex process automation.
