Automation Components Inc (ACI) DRN4 Control

The Automation Components Inc (ACI) DRN4 Control is a high-performance resistive output motor actuator interface designed to bridge the gap between diverse DDC system signals and standard 0 to 135 ohm motor actuators. This versatile module is an ideal solution for electric actuator control, serving as an electronic potentiometer or for resistive sensor simulation in complex HVACR environments. Featuring an 8-position DIP switch, the DRN4 allows for easy field selection of multiple input types, including analog voltage (0-10 VDC), current (4-20 mA), pulse, and floating point control signals. Its compact plastic enclosure is designed to mount directly to a 1/2" knockout on the motor actuator, simplifying installation and reducing wiring clutter. With color-coded wire leads and spade connectors, the DRN4 provides a seamless electrical connection for technicians looking to upgrade or replace Honeywell Modutrol IV Series 90 motor pots or similar resistive networked systems.

• Universal Compatibility: Accepts voltage, current, pulse, and floating-point signals for maximum system flexibility.
• Precise Signal Conversion: Ramps DDC inputs to a stable 0 to 135 ohm resistance network with 32-step resolution.
• Simplified Installation: Direct-mount enclosure fits standard knockouts, accompanied by pre-terminated, color-coded leads.
• Field Adjustable: Features a local override button and accessible DIP switches for rapid configuration and testing.
• Reliable Integration: Perfectly suited for motor pot replacement and DDC to resistive signal interfacing.

What actuators are compatible with the ACI DRN4?
The DRN4 is specifically engineered for actuators requiring a 0 to 135 ohm input, such as the widely used Honeywell Series 90 Modutrol motors.

Do I need additional accessories for triac input signals?
While the DRN4 supports many inputs natively, certain triac signal sources require an external adapter kit. Notable exception: Johnson Control triac signals include a necessary 1,000-ohm resistor with the unit.

Can the rate of change be adjusted for floating point inputs?
The standard floating point full-scale rate of change is fixed at approximately 55 seconds to ensure smooth and stable actuator positioning.
