英文介绍

 

The Allen-Bradley 1794-OE12 is a high-density analog output module that is part of the Flex IO product family. The module has twelve (12) output channels that can be configured for 0-20mA, 4-20 mA current signals, and +/- 10VDC voltage signals. The module's channels are non-isolated and support a single-ended cabling configuration.

The 1794-OE12 is used with terminal bases such as 1794-TB3G and 1794-TB3GS with key switch position 4. It has an open housing, which means that the module and the entire Flex I/O assembly must be installed inside the housing to provide adequate protection for industrial elements.

The 1794-OE12 is equipped with a built-in analog-to-digital circuit (ADC) converter. It converts digital data into analog signals with a resolution of 16 bits and a 2-complement data format. For both voltage and current signals, the absolute accuracy of each output channel is 0.1% full scale @ 25 °C, with an accuracy drift of 0.004% full scale /°C for both signal configurations.

The current consumption of the 1794-OE12 is 80 mA, and the supply voltage is required to be 10.5-31.2VDC. Its power consumption is 7.68W@24V DC, heat dissipation is 26.2 BTU/ hr@24V DC, isolation voltage is 50V (continuous), basic insulation type. There is no isolation between channels. It has a physical dimension of 94.0 x 94.0 x 53.3 mm or 3.7 x 3.7 x 2.1 inches and has a built-in group diagnostic LED.

The 1794-OE12 has an operating temperature of -20 to 60 °C (-4 to 140 °F), a storage temperature requirement of -40 to 85 °C (-40 to 185 °F), and a relative humidity of 5-95%. Its operating shock and vibration ratings are 30 g and 5 g @ 10... 500 Hz.

1794-OE12 does not require calibration. It has a physical size of 3.7 x 3.7 x 2.1 inches and an open housing. It can be mounted using DIN rails. The output of the 1794-OE12 module is 0 mA until the configuration is complete. After configuration, the output signal range is 4-20 mA and 0-20 mA, both of which can be configured by the user, while the configurable output voltage range is +/-10V. The module's mA output resistance load is 0-750? At 24V DC and maximum voltage output current load 3 mA. The current resolution is 0.641 μA/cnt and the voltage resolution is 320 μV/cnt. The module has a nominal external DC power supply of 24V DC and an external DC power supply voltage range of 10-31.2V DC, including 5% AC ripple. The module's external DC power supply current is 720 mA (10V DC) and 320 mA (24V DC). The 1794-OE12 module also features a FlexBus current of 80 mA and a continuous isolation voltage of 50V, which has been tested at 850V DC for 60 seconds, especially between the user and the system power supply. The absolute accuracy of the voltage and current terminals is 0.1% full scale (25% each), and the accuracy of the voltage and current terminals varies with temperature by 0.004% full scale/Celsius. The module has a maximum power consumption of 4W at both 10V DC and 31.2V DC, 4.3W at 24V DC, and a maximum heat dissipation of 4.7BTU /hr at 24V DC. The module has an operating temperature of -20 to 60 degrees Celsius and a storage temperature of -40 to 85 degrees Celsius. It also has a relative humidity of 5-95% and is non-condensing. The module also has a working shock of 30 g, a non-working shock of 50 g and a working vibration of 5 g at 10-500 Hz.
