PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-ACN15 is a FLEX I/O ControlNet Adaptor. It interfaces up to eight modular I/O units within the Flex I/O 1794 platform. The unit operates with an input supply voltage ranging between 19.2 and 31.2 volts DC. Normal operation requires a steady input current of 400 mA.
The adaptor enables network communication at a transfer rate of 5 Mbps. It delivers 640 mA of output current at 5 volts DC to connected modules. Maximum power dissipation equals 3.4 Watts at an input level of 19.2 volts DC. An integrated rotary dial provides physical node selection during hardware setup.
