【英文介绍】

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 the Flex I/O communication adapter and terminal dock to implement a distributed I/O architecture.

Using 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 produce a compatible signal range.

The Flex I/O analog input module has 12-bit resolution when configured in unipolar mode and 11-bit plus sign when configured in bipolar mode. It uses successive approximation conversions and saves the converted data in EFT-adjusted 16-bit 2-complement data format. Its conversion rate is 256? The absolute accuracy of all channels is 0.20% full scale (at 25°C), the voltage accuracy drifts to -0.00428% full scale /°C, and the current input accuracy drifts to 0.00407% full scale /°C. The 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 the use of terminal blocks to install and connect input signal lines. The compatible terminal bases are 1794-TB2, 1794-TB3 and 1794-TB3S, 1794-TB3T and 1794-TB3T. The module requires only one terminal block.

The Flex I/O module is compatible with Flex I/O communication adapters such as Ethernet, ControlNet, remote I/O adapters.

The module does not require calibration beyond factory Settings. It measures 3.7 x 2.1 x 31.8 inches and can be mounted on a DIN rail or directly onto the panel. The 1794-IE8 module can be installed on the 1794-TB2, 1794-TB3S, 1794-TB3ST, 1794-TB3T, or 1794-TB3 terminal base unit. It also comes with a power and status indicator and has an open housing. The module has a voltage specification of 24 volt DC nominal value 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, as well as voltage signal ranges with +/-10VDC and 0-10VDC inputs. It has A voltage resolution of 2.56 mV/cnt(unipolar) and 5.13 mV/cnt(bipolar), and a current resolution of 5.13 A/cnt. The module has a maximum voltage overload of 30 continuous volts and a maximum current overload of 32 continuous MA, but there is only one channel for both.
