It also has two (2) single ended non isolated analog output channels, configurable for 0-20 and 4-20 mA as well as+/-10VDC. This module requires the use of 1794-TB2, – TB3, – TB3S, – TB3T, and – TB3TS terminal block units.
About 1794-IE4XOE2
Allen Bradley 1794-IE4XOE2 is a combination I/O module. This module is part of the Flex I/O product family widely used for implementing distributed I/O architectures. The 1794-IE4XOE2 has a combination of analog and input channels, as the module has four (4) single ended, non isolated analog input channels and two (2) single ended, non isolated analog output channels.
The analog input channel can be configured to receive analog input signals, such as 0-20 mA and 4-20 mA signals, as well as 0-10VDC and+/-10VDC voltage signals. It has a built-in analog-to-digital converter (ADC) that uses the successive approximation method. The conversion rate of each channel is 256 μ s. Step response is 63% of voltage 9.4 ms and current 18.2 ms. Its absolute accuracy at 25 ° C is 0.20% of full scale. This module saves the converted data in a left aligned 16 bit 2s complement data format.
The 1794-IE4XOE2 module contains four single ended non isolated inputs. The resolution of a unipolar input is 12 bits, while the resolution of a bipolar input is 11 bits. The data format is a left aligned 16 bit 2 complement. The conversion type supported by the 1794-IE4XOE2 module is successive approximation conversion. The input current terminal can be selected between 4 to 20 mA or 0 to 20 mA. The input voltage terminal can be selected between ± 10 volts and 0 to 10 volts. The normal mode rejection ratio of the voltage terminal is -3 dB at 17 Hz and -10 dB at 50 Hz. The current terminal’s constant mode rejection ratio is -3 dB at 9 Hz and -15.3 dB at 50 Hz. The input impedance at the voltage end is 100 kiloohms, and the input impedance at the current end is 238 ohms. The 1794-IE4XOE2 module contains two single ended non isolated outputs. The conversion type is pulse width modulation. The current load on the voltage output is 3 mA (maximum). The dimensions of the 1794-IE4XOE2 module are 1.8 x 3.7 x 2.1 inches. The required power supply is 24 VDC (19.2 to 31.2 VDC), with a current of 70 mA at 24 VDC. The maximum heat dissipation is 13.6 BTU/hour, and the maximum power consumption is 4 watts (31.2 volts DC).
