输入模块 1794-OE4  提供信号调理功能

Description: Allen-Bradley 1794-OE4 is a Flex I/O analog output module. The module has four (4) analog output channels providing analog output signals ranging from 0 to 20 mA; 4 to 20 mA; +/- 10 volts direct current; 0 to 10 VDC. It has a 12-bit resolution and is compatible with terminal bases such as 1794-TB2, -TB3, -TB3S, -TB3T, -TB3TS, and -TBN.

An input module is a device or component used to convert an external signal into a digital signal that can be recognized by a computer. It is commonly used to receive various types of input, such as sensors, buttons, switches, encoders, etc., and convert it into a digital signal that a computer can process.

The resolution of the 1794-OE4 is 12 bits plus sign, and the specific increment and decrement of voltage and current are 2.56mV/cnt and 5.13μA/cnt, respectively. The module's analog data is stored as left-justified registers, which are 16-bit 2's complement. The register is converted by pulse width modulation.

The 1794-OE4 supports installation using Flex I/O communication adapters, including 1794-ACN15, 1794-ACNR15, 1794-AND, 1794-AENT, and 1794-AENTR. It can also be used with MicroLogix compact controllers via the 1794-ASB and 1794-APB communication adapters.

The main function of the 1794-OE4 input module is to convert analog or digital signals into a format that a computer can understand and process. It usually consists of one or more input channels, each of which can receive a different type of signal and convert it into a digital signal. The input module can also provide signal conditioning functions, such as filtering, amplification, calibration, etc., to ensure the quality and accuracy of the input signal.

The 1794-OE4 input module is usually connected to a computer or other control device to transmit the input signal to the computer or control device through a communication interface (such as USB, RS232, Ethernet, etc.). In industrial control, automation, instrumentation and other fields, input modules are widely used in data acquisition, process control, machine vision and other aspects.
