About 1794-FLA

The Allen-Bradley 1794-FLA is a 1794 FlexLogix Extended Local I/O Adapter module. It is used for interlacing FLEX I/O modules and I/O scanner ports through a communication network. It has a dimension of 3.4 x 3.7 x 3.6 in. and 0.6 lbs.
The 1794-FLA adapter module has a 24V DC nominal input voltage with a 19.2 – 31.2V DC input voltage range. It has a capacity of up to 8 I/O modules. It has an input current of 0.39A at 19.2V DC and of 0.25A at 24V DC. It has a power consumption of 6.5W at 24V DC and maximum power dissipation of 7.5W at 19.2V DC and 6W at 24V DC. It has a maximum backplane current of 653mA at 5.1V DC. It is installed using DIN rail. It has various communication options such as ControlNet, DeviceNet, EtherNet/IP, and Universal Remote I/O.
The 1794-FLA adapter module has a power supply to convert 24V DC to 5V DC so the backplane can power the FLEX I/O modules. One 1794-FLA adapter module communicates with a maximum of eight I/O modules, thus providing connections to 256 digital I/O points, 64 analog input points, 32 analog output points, or in any combination according to application requirements. It has a 0 - 55 °C (32 - 131 °F) operating temperature and a 5 - 95% noncondensing relative humidity.
