产品介绍
The Allen-Bradley 1771-NOC High Resolution Analog Output Module is a precision analog output module designed for the PLC-5 based 1771 I/O platform from Allen-Bradley. It is used to control field devices that require current-based analog input signals, converting digital instructions from the PLC into precise 0–25 mA current outputs.
The module supports eight high-resolution output channels, allowing the PLC to control multiple devices such as valves, actuators, or process instruments simultaneously. Its fast signal response ensures accurate and timely control for critical automation processes, with typical AC and DC signal delays / 45–50 ms.
Installed in a 1771 I/O chassis, the 1771-NOC communicates with the PLC-5 processor via the backplane. It is ideal for process control applications requiring precise analog output regulation and reliable integration with other PLC modules.
