【英文介绍】

Allen-Bradley 1794-OE4 is an analog output module in the Flex IO product family. As part of the distributed I/O node, the module is compatible with Flex I/O communication adapters such as Ethernet, ControlNet, Profibus, and Remote I/O. The module features four (4) user-configurable output channels designed to provide 0 to 20mA, 4 to 20mA current signals and +/- 10VDC and 0 to 10VDC voltage signal signals. This module enables automatic and manual control of modulation devices such as variable frequency drivers (VFDS), modulation control valves, converters, transducers, dampers, louvers and other final control elements (FCE). The output channel of this module supports a non-isolated single-ended configuration.

The 1794-OE4 has a 12-bit plus resolution, specific increments and decrement of voltage of 2.56mV/cnt and current of 5.13 μa /cnt. The module's analog data is stored in a registration format of left-justified, 16-bit 2 complement. The register is converted using pulse width modulation.

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

The 1794-OE4 is compatible with various terminal bases such as 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TB3T, 1794-TB3TS, and 1794-TBN. Only one terminal block is required for module installation. The terminal base provides DIN rail accessories and output signal terminals. 1794-OE4 The required key switch position is 4.

The module measures 94.0 x 94.0 x 53.3mm or 3.7 x 3.7 x 2.1 inches. It has a built-in group diagnostic led, consisting of a (1) green/red power/status indicator.

1794-OE4 Has a green status indicator to monitor the operation of the module. The module does not require calibration. The module has an output resolution of 12-bit + symbol, a voltage of 2.56 mV/cnt, and a current output of 5.13 μA /cnt. It uses pulse width modulation as its output conversion type, with an output conversion rate of 1.024 milliseconds for all channels. the
