ZiP Data Acquisition

Zip is a modular data acquisition and control system that combines "plug-and-go" engineering with data transfer across Compass and IT networks. Zip is ideal for distributed monitoring and switching applications where network communications are essential. Typical uses include monitoring and generating alarms for temperature, humidity and doors in IT server racks, or monitoring the status of uninterrupted power supplies and stand-by generators. ZiP can also be used for collecting data for environmental logging, such as temperature values in refrigeration units and cold stores.
ZiP is also available as a door access controller module, allowing one data network to be used for monitoring, plant control and door access applications.
