Acromag 811A-0100 IntelliPack Alarm Module Card

Acromag's 811A-0100 IntelliPack Alarm Module Card is a single‑channel intelligent alarm in the IntelliPack 800A Series that monitors one DC voltage or current input and drives a built‑in DPDT relay for local control. The device is powered from 10 to 36 V DC and, with its front‑panel push‑buttons and status LEDs, supports Windows‑based configuration via the IntelliPack software to set alarms, thresholds, and control logic; once configured, it can operate independently of a host PC. Available alarm functions include limit, window, deviation, rate‑of‑change, and peak/valley detection, plus an on/off controller, making it suitable for process monitoring, interlocks, and signaling in industrial automation. The 811A‑0100 uses a compact enclosure measuring 5.0 in long × 1.25 in wide × 4.5 in high and weighs about 8 oz, with a DPDT relay offering two changeover contacts (N.O./COM/N.C. for each pole) to switch two circuits. This model is designed for applications where a single DC input must be compared against user‑defined setpoints to actuate a relay, such as motor or valve control, alarm signaling, or safety interlocks within distributed control systems.
