Acromag 811A-0200 InteliPack Alarm

The Acromag 811A-0200 InteliPack Alarm is a microcontroller-based alarm trip module engineered for critical process monitoring and annunciation in industrial control systems. It accepts DC current (0 to 22 mA), DC voltage (±100V), and AC current inputs via optional sensor, delivering dual SPDT relay outputs rated at 25V DC @ 5A or 120/240V AC @ 5A. Configuration occurs through Windows-based software or front-panel push-buttons and LED indicators, enabling independent operation without host supervision after setup.

Technical Specifications

• Input Ranges: DC current 0–22 mA; DC voltage ±100V; AC current via external 5020-350 sensor


• Output Relays: Two independent SPDT electro-mechanical relays; AgCdO contacts; 20 million cycle mechanical life; failsafe/non-failsafe configurable


• Analog Processing: High-resolution Sigma-Delta ADC with low-noise characteristics


• Power Supply: 10–36V DC; draws 170 mA @ 10V, 140 mA @ 12V, 110 mA @ 15V, or 70 mA @ 24V


• Processor: Advanced microcontroller with downloadable flash memory and EEPROM


• Indicators: Green LED (power); yellow LED (status/alarm)


• Physical: 1.05" W × 4.68" H × 4.35" D (26.7 mm × 118.9 mm × 110.5 mm); self-extinguishing nylon 6.6 enclosure

Key Features

• Configurable alarm functions: limit, window, on/off control, deviation (dual-input), rate-of-change, peak/peak-valley detection
