Product Description
Product Overview
The Allen-Bradley 1756-OF8 is a ControlLogix Analog Output Module designed for precise control of analog signals in industrial automation systems. Manufactured by Allen-Bradley, a brand under Rockwell Automation known for its robust industrial solutions, this module is part of the ControlLogix platform, widely used in applications such as process control, manufacturing, and energy management. It features eight analog output channels, configurable for voltage (±10 VDC) or current (0-20 mA) signals, making it suitable for driving field devices like valves, actuators, and recorders, or retransmitting signals to instrumentation. The 1756-OF8 offers high-resolution output, short-circuit protection, and overvoltage safeguards, ensuring reliable operation in demanding environments. It can be installed in local or distributed I/O chassis, integrating seamlessly with ControlLogix controllers via EtherNet/IP or ControlNet networks.
