Dual or quad DC alarm module

Dallas, Tex. —AS4F alarm module provides quad or dual relay outputs at preset analog input levels. Programmable in engineering units from the front-panel, the 4-digit LED display continuously displays the process variable, or shuts off after a period of inactivity. Signal preprocessing functions include alarming on an averaged signal, on-delay alarming, which requires the alarm trip poin...

Dallas, Tex. —AS4F alarm module provides quad or dual relay outputs at preset analog input levels. Programmable in engineering units from the front-panel, the 4-digit LED display continuously displays the process variable, or shuts off after a period of inactivity. Signal preprocessing functions include alarming on an averaged signal, on-delay alarming, which requires the alarm trip point to be maintained by a user-defined time period before the output is activated, and alarm dead band. AS4F can be panel- or DIN-rail mounted. Available inputs are 4-20 mA, 0-10 V, 0-5 V, and 1-5 V. Output choices are 4 points of NO contacts, 4 points of NC contacts, or 2 points of SPDT contacts.
