Product Overview

YS1500 is compact single‑loop PID controller from Yokogawa, designed for independent process loop regulation. It receives temperature, pressure and flow field signals, performs PID closed‑loop control and outputs control signals to valves and actuators. Bumpless manual‑auto transfer guarantees smooth switch for field operation. Suitable for small‑scale process units and DCS backup control loops. Modbus RTU enables remote data monitoring. Obsolete spare hardware available as refurbished and surplus tested units for industrial panel maintenance and replacement.

Application Notes

‑ Install in standard instrument control panel. ‑ Use shielded cable for analog input signals. ‑ Perform bumpless transfer test after parameter commissioning. ‑ Typical deployment: process‑plant single‑loop controller spare‑part stocking.
