ACI 101794 AIM2 Analog Isolation Module with Rescaling

The ACI 101794 (AIM2) is an analog isolation module designed for building automation and HVAC control applications. This module provides optical isolation for analog input signals, protecting sensitive control equipment from electrical interference and ground loops.

Key Features:

• Accepts analog input signals from 0-20 VDC or 0-20 mA
• Produces isolated output signals within the same ranges
• Optical isolation technology prevents ground loops and electrical interference
• Rescaling capability allows input and output range adjustment
• Preset and adjustable configurations for voltage or current signals
• Current signals support both sink and source on input and output
• Field calibratable for easy setup and installation
• Requires 24 VAC power with floating secondary transformer
• Includes onboard 24 VAC isolation transformer for isolated output

Common applications include isolating grounded electrical actuators, fluorescent light dimmers, variable frequency motor drives, and providing general isolation of analog signals in building automation systems. The module protects control systems from voltage spikes and electrical noise while maintaining signal integrity.
