801A: Intelligent Alarm, Universal TC/RTD/mV Input
• Thermocouple (J, K, T, R, S, E, B, N), RTD (Pt, Ni, Cu), millivolt (±100mV DC), resistance (0 to 500 ohms) input
• Single or dual mechanical relay alarm outputs
• 10-36V DC power
• Software configured
• Multi-function alarms (limit, window, deviation, rate-of-change, peak/valley detection)
• On/off controller capability
IntelliPack alarms compare inputs against user defined limit setpoints 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 XP and newer program. Field adjustments and recalibration are quickly performed with front-panel push-buttons and status LEDs. Once configured, IntelliPacks operate independent of any host computer.
