Automation Components Inc (ACI) ARM2 Module

The Automation Components Inc (ACI) ARM2 is a versatile analog signal resettable monitor designed to function as a high-precision HVAC signal splitter. Engineered for seamless integration into building automation systems, the ARM2 accepts a single analog voltage or current input and converts it into two identical, non-isolated DC current sourcing outputs. This analog to DC signal converter is ideal for applications requiring redundant monitoring or parallel control of dampers and actuators. It features adjustable gain and offset, allowing for precise field calibration to meet specific site requirements. The unit includes a regulated 23 VDC output power supply to provide excitation for external sensors and supports voltage divider applications for resistance inputs. With field selectable ranges and the ability to operate in either direct or reverse acting modes, the ARM2 provides the flexibility needed for complex industrial automation signal conditioning tasks, ensuring reliable performance across diverse 24 VAC or VDC powered environments.

Key Benefits

• Dual Output Scaling: Seamlessly split one input into two identical sourcing outputs that track each other perfectly.
• Broad Compatibility: Supports a wide range of input signals including mA, VDC, and resistance via voltage dividers.
• On-Board Power: Features a regulated 23 VDC supply to simplify wiring by powering secondary sensors directly.
• Flexible Logic: Field selectable direct or reverse acting modes to accommodate various control sequences.
• Simplified Calibration: Integrated potentiometers allow for easy field adjustments of gain and offset to ensure signal accuracy.

Common Questions

How do I use the ARM2 as a signal splitter for HVAC actuators?
The ARM2 accepts your primary controller signal (e.g., 0-10V) and provides two independent current signals to drive two separate actuators simultaneously with identical scaling.

Can the ARM2 convert a resistance signal from a thermistor?
Yes, by using voltage divider applications, the ARM2 can process resistance inputs and convert them into standard DC current outputs.

Does this module require a specific power type?
The ARM2 is highly flexible and can be powered by either a 24 VAC or 24 VDC power source, making it compatible with most standard control panels.
