Yokogawa YS1700-000 Single Loop Controller

Feature & Principle

It is a panel-mounted programmable single-loop controller of Yokogawa YS1000 series. It receives analog signals from temperature, pressure and flow transmitters and executes dual PID closed-loop control. It supports function block programming and legacy text programming, compatible with old YS170 and SLPC program conversion. It integrates hard manual backup function to maintain valve output when communication or host system fails. It supports RS485 Modbus communication to exchange data with PLC, HMI or CENTUM DCS, widely used as independent control or DCS backup loop.
