製品紹介
The Allen-Bradley 1794-ASB2 Flex Remote I/O Adapter Module is a compact communication interface designed to connect Flex I/O modules to a Remote I/O (RIO) network. It enables distributed I/O systems to communicate efficiently with controllers, providing a reliable solution for legacy and existing industrial automation architectures.
This adapter supports up to 2 Flex I/O modules, making it suitable for small-scale or localized I/O expansion. With an input voltage range / 11–31.2 V DC and a power consumption / 330 mA, the module ensures stable and efficient operation. It also features 500 V AC isolation, enhancing protection between the network and field-side devices.
The 1794-ASB2 interacts directly with the Flex I/O backplane, managing data exchange between connected modules and the Remote I/O scanner. Its compact size, DIN rail mounting capability, and open-style design make it easy to install in control panels where space and simplicity are important.
