WDA, SBHM, and older History Modules are available from WPC. For a specific quote, tell us your requested drive size, whether you need single or dual logical drives, and whether or not you require redundancy.
The History Module (HM) provides file server capabilities for the Honeywell LCN. The HM takes continuous history, which can be used for event or error tracking. History modules can be configured with redundant drives for improved reliability.
WPC now offers solid state replacements for the Seagate drives used in the dual-logical WDA History Module, and for the Single Board History Module.
