1794-OE12 is a high-density analog output module manufactured by Allen Bradley, belonging to the Flex IO product series. This module has twelve output channels that can be configured for 0-20mA, 4-20mA current signals, and+/-10VDC voltage signals, but the channels are non isolated and support single ended wiring configurations. In addition, the 1794-OE12 module is used in conjunction with terminal bases (such as 1794-TB3G and 1794-TB3GS), and its key switch position is 4.
The 1794-OE12 module is designed with an open housing, which means that the entire module and Flex I/O components must be installed inside the housing to provide sufficient protection for industrial elements. The module is also equipped with an analog-to-digital circuit (ADC) converter inside, which can convert digital data into analog signals with a conversion resolution of 16 bits, and the data format adopts the complement data format of 2.
In terms of electrical performance, the current consumption of the 1794-OE12 module is 80mA, and the power supply voltage requirement is 10.5-31.2VDC. In addition, this module has a wide range of application areas, including CNC machinery, metallurgy, oil and gas, papermaking and printing, textile printing and dyeing, machinery, electronic manufacturing, automotive manufacturing, tobacco, plastic machinery, power plants, water treatment/environmental protection, municipal engineering, steel mills, cement plants, robots, rail transit and other industries.
Regarding module programming and interfaces, it has the characteristic of being easy to use. The graphical symbols and expressions of its ladder diagram language are quite similar to relay circuit diagrams, making it convenient for people who are not familiar with electronic circuits and computer principles to use computers for industrial control.
Overall, the 1794-OE12 module plays an important role in industrial automation control systems due to its high-density output channels, flexible signal configuration, industrial grade protection design, and easy-to-use programming interfaces.
