About 1794-IE8:
Allen-Bradley 1794-IE8 is a component module of the Flex I/O product family.
The module is an analog input module that is used with a Flex I/O communication adapter and terminal dock to implement a distributed I/O architecture.
The module uses the module's eight (8) single-ended, non-isolated, user-configurable channels capable of receiving 0 to 20mA, 4 to 20mA, +/ -10VDC, and 0 to 10VDC input signals. The module is capable of connecting instruments such as field transmitters, analog indicating instruments, loggers, process loop controllers and other analog instruments that generate a compatible signal range.
This Flex I/O analog input module is configured as a 12-bit sign in unipolar mode and an 11-bit plus sign in bipolar mode.
It uses successive approximate conversions and saves the converted data in an EFT-aligned, 16-bit 2s complement data format.
It has a conversion rate of 256 seconds on all channels with an absolute accuracy of 0.20% at full scale @25°C,
The voltage accuracy drift is -0.00428% full scale /°C and the current input is 0.00407% full scale /°C. This module does not require calibration.
1794-IE8 requires an external supply voltage range of 10.5-31.2VDC and a nominal supply voltage of 24VDC.
It requires 60 mA of supply current. It requires installation and connection of input signal wiring using a terminal base.
Compatible terminal bases are 1794-TB2, 1794-TB3 and 1794-TB3S, 1794-TB3T and 1794-TB3TS. Modules require only one terminal base.
This Flex I/O module is compatible with Flex I/O communication adapters such as Ethernet, control network, remote I/O adapters.
This module does not need to be calibrated beyond factory Settings. It measures 3.7 x 2.1 x 31.8 inches and can be mounted on a DIN rail or directly panel mounted.
The 1794-IE8 module can be installed on a 1794-TB2, 1794-TB3S, 1794-TB3ST, 1794-TB3T, or 1794-TB3 terminal base.
It also comes with power and status indicators and has an open housing.
The module has a rated voltage specification of 24 volts DC and a supply voltage range of 10.5 to 31.2 VDC, including 5% AC ripple.
The module is compatible with analog current signal ranges such as 0-20mA and 4-20 mA, and voltage signal ranges of +/-10VDC and 0-10VDC inputs.
The voltage resolution is 2.56 mV/cnt (unipolar) and 5.13 mV/cnt (bipolar), and the current resolution is 5.13 μA/cnt.
The module has a maximum voltage overload of 30 volts continuous and a maximum current overload of 32 mA continuous, but only one channel each.
The 1794-IE8 module has a maximum power consumption of 3 W and a heat dissipation of 10.2 BTU/ hour, both at 31.2 volts DC.
It has an operating vibration of 500 g at 5 to 10 Hz. It has a working shock of 30 g and a non-working shock of 50 g.
The module operates in a temperature range of -20 to 55 degrees Celsius, while its storage temperature ranges from -40 to 85 degrees Celsius.
The 1794-IE8 module has 20.25% full scale current input and voltage input accuracy at 0 ° C, although the voltage input includes gain, offset, repeatability and nonlinear error terms. The step response of the voltage terminal to 63% is 9.4 ms and the current terminal is 18.2 ms.
It has an absolute accuracy of 2.25% full scale at 0 degrees Celsius, an accuracy drift of 0.00428% full scale per degree Celsius for the voltage terminal, and 0.00407% full scale for the temperature of the current terminal.
