The Allen-Bradley CompactLogix LDT 1790-T8BV8VX is a versatile Input/Output (I/O) expansion module designed for use with the Allen-Bradley CompactLogix L Series Controllers. This expansion module provides 8 universal input and 8 universal output points, offering flexibility to handle various signal types in a compact package. This module is well-suited for applications where space is limited, as it can be easily integrated into control systems to expand the I/O capacity.
The universal I/O points of the 1790-T8BV8VX module can be configured to support multiple signal types. The inputs can be set up for discrete, analog input (4-20 mA), or temperature inputs (Junction and T-type thermocouples), while the outputs can be configured as open-collector or source type, depending on the application requirements.
This module communicates with the controller via the standard Linx Communication Network, allowing for seamless integration and easy configuration using the Rockwell RSLogix 5000 or Studio 5000 software packages. Additionally, the module is compliant with the IEC-61131-3 programmable controller standard, enabling users to develop and implement control projects without requiring extensive hardware expertise.
The Allen-Bradley 1790-T8BV8VX is engineered for robust performance and features a rugged design optimized for industrial applications. It can withstand operating temperatures ranging from -30 C to 65 C ( Up to -22 F to 149 F), making it an ideal choice for a wide range of industries and applications.Integrating this compact but powerful expansion module into a control system allows users to increase flexibility, expand I/O points, and ensure reliability for their operation.
