811A, 812A Intelligent Alarm with DC Voltage/Current Input Description
IntelliPack alarms compare inputs against user-defined limit set-points to control built-in relays.
Each unit offers a selection of input ranges and alarm functions to handle a broad range of applications. As your needs change, you can easily reconfigure the unit for different ranges or functions. Alarm functions available on all models include on/off controller, limit alarm, window alarm, deviation alarm, rate-of-change alarm, and peak/valley detection.
Setup is very easy. IntelliPack alarms are configured through a user-friendly Windows 7 or newer program. Field adjustments and re-calibration are quickly performed with front-panel push-buttons and status LEDs. Once configured, IntelliPacks operate independent of any host computer.
Performance
General Input
