Product Description
The YS170-012 is a versatile microprocessor-based programmable controller from the Yokogawa YS100 series. Engineered for sophisticated process control, it provides dual-loop capability, allowing simultaneous management of two independent control loops. Its high-reliability architecture includes a manual backup mode, ensuring process continuity even if the CPU fails.
Featuring a high-visibility vacuum fluorescent display (VFD) with multi-color bargraphs, the YS170-012 provides clear visualization of process variables, setpoints, and manipulated variables. Its programming flexibility supports advanced control strategies—such as cascade, ratio, and feed-forward control—via functional blocks or custom logic. This compact panel-mount controller bridges the gap between simple PID controllers and complex DCS systems, offering robust performance in industrial environments.

FAQ
Q1: Can it be programmed from the front panel?
Basic parameters can be adjusted via the faceplate; full functional programming is done using YSS10 Configuration and Programming Software.
Q2: What happens if the CPU stops?
The integrated manual station allows operators to switch to manual mode and directly adjust outputs via the analog backup circuit.
Q3: Is Modbus communication supported?
Yes, with the appropriate communication card, the YS170-012 interfaces with SCADA systems or PLCs via RS-485 Modbus RTU.
