Series-ARM
Analog Current/Voltage Rescaling Module
- Rescales analog control signals: The ACI ARM accepts voltage or current input signals and converts them to another voltage or current output signal for better controller compatibility.
- Ideal for signal adaptation: Use it for resistance-to-current, resistance-to-voltage, voltage-to-current, current-to-voltage, and other non-compatible signal conversions.
- Flexible field adjustment: Multi-turn potentiometers allow fine adjustment of gain, offset, attenuation, and reverse-acting output for precise setup.
- Improves sensor range matching: Helps shrink or expand sensor ranges, increase analog input resolution, and adapt signals to match BAS controller requirements.
- Supports reverse signal operation: Can invert an output signal, making it useful when a controller or actuator requires reverse-acting control.
- Built-in sensor power: Includes a regulated 20 VDC power output for powering compatible sensors during signal conversion applications.
- Wide input compatibility: Supports 0-35 VDC, 0-44 mA, and resistance inputs up to 500,000 Ω using voltage divider applications.
- Panel-ready interface module: Compact snap-track design with captive screw terminals supports clean installation in control panels and equipment enclosures.
