Universal Input Intelligent Alarm 801A

The 801A is part of the Acromag IntelliPack family. Intellipack alarms compare inputs against user defined limit set points to control built-in relays.

This software configured module accepts Thermocouple, RTD, millivolt and resistance inputs and produces single or dual mechanical relay alarm outputs.

Acromag’s 801A is a Universal Input Intelligent Alarm Module.

Firstly, each unit offers a selection of input ranges and alarm functions to handle a broad range of applications. Therefore, as requirements change the unit can be reconfigured for different ranges or functions.

Secondly, Alarm functions available on all models include on/off controller, limit alarm, window alarm, deviation alarm, rate-of-change alarm, and peak/valley detection.

Thirdly, 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.
