This document describes a contact input module of GS WM8864-00 2006.03 4th Edition, which is used to convert contact signals for input into the Field Information Server (FiS). It has the characteristics of small size and economic efficiency, and comes with a House Keeping (HK) function to monitor module failures. It is also possible to select analog output as an additional specification.
This document describes the WM8864 contact input module, a compact and economical converter that can be combined with a WM6801 processing module to digitize signals. It includes optional analog output capability and a housekeeping function for monitoring module failures.
Technical information includes input sense current, power requirements, mechanical dimensions, connector pinouts, analog output configurations, and allowable load resistances. The manual also lists accessories, part numbers, and reference drawings for the module. This manual is written in Japanese.
