Overview
The YS1500 Indicating Controller comes with a variety of built-in functions that are needed in process control. The YS1500 is configured upon shipment from the factory so that only the minimum required functions are available, but control functions needed for a user's specific application can be selected by setting various parameters.
Overview of YS1500 Functions
Table 1 lists some of the major functions of the YS1500 as compared with those of the earlier model, the YS150.
