AC6A1CA Fireye Actuator

Overview

The Fireye AC6A1CA is a keypad-programmable, direct-coupled, modulating rotary actuator designed for precise control in burner and valve management systems. As part of the AC Series, this motor is typically utilized alongside electronic controls to regulate process temperatures by adjusting the position of dampers or butterfly valves. It is engineered to replace legacy models like the Eclipse FPRA6A1CA, providing a modern, reliable solution for air and gas flow control. The unit features an integrated display and keypad that are oriented for upright (vertical) mounting, ensuring ease of operation and visibility in standard installations.

Features

• Solid-state electronics for reliable and precise modulating control.
• Integrated seven-segment LED display with membrane keys for local position monitoring and manual control.
• Keypad programmable parameters including minimum/maximum travel positions and rotation direction.
• Versatile input options supporting 4-20mA, 0-10Vdc, and isolated digital switch inputs.
• Two internal auxiliary contacts provided for position feedback and signaling.
• Selectable clockwise or counterclockwise rotation to suit various valve and damper configurations.
• NEMA 4 (IP66) rated construction for protection against dust and water in industrial environments.
• Direct coupled design eliminates the need for complex linkages.

Applications

The Fireye AC6A1CA is primarily used in commercial and industrial combustion systems to provide rotary positioning for air dampers and fuel butterfly valves. It is a critical component in parallel positioning systems, allowing for the fine-tuning of fuel-to-air ratios to optimize burner efficiency. Common applications include regulating process heat in boilers, furnaces, and kilns. Because of its programmable nature and standard 90-degree stroke, it is highly compatible with a wide range of butterfly valve stems and air-gas damper assemblies used in modern burner management environments.
