- Description 1790-T8BV8VX A-B CompactBlock LDX Expansion Block Product Dimensions： Product Description (Detailed Explanation) The 1790-T8BV8VX is a DC combination expansion module that provides both inputs and outputs in a single, ultra-compact housing. It is specifically designed to be “daisy-chained” to a CompactBlock LDX base module via a built-in ribbon cable. This module features 8 Universal Inputs and 8 Sinking Outputs. The “Universal” nature of the inputs allows them to be wired as either Sink or Source, providing significant flexibility during field installation. The “V” in the part number denotes Sinking Outputs, meaning the module switches the negative side of the load. The “T” indicates that it uses Screw-Clamp Terminals, which are preferred for secure, vibration-resistant connections in industrial environments. Product Parameters (Technical Specifications) Parameter Category Specification Product Series CompactBlock LDX I/O I/O Configuration 8 Universal Inputs / 8 Sinking Outputs Input Type 24V DC Sink or Source (Universal) Output Type 24V DC Sinking (Transistor) Nominal Voltage 24V DC Voltage Range 9.6V DC to 28.8V DC Output Current 0.5 A per channel (4.0 A max per module) Termination Type Screw-Clamp Terminal Block Isolation 50V (Continuous), Basic Insulation Type Status Indicators 16 yellow I/O status LEDs, 1 red/green Module status Operating Temp. $0^{\circ}C$ to $ 55^{\circ}C$ ($32^{\circ}F$ to $ 131^{\circ}F$) Dimensions 104 mm x 52 mm x 42 mm Product Advantages (Key Benefits) Space Efficiency: Its extremely small footprint makes it ideal for mounting inside small operator consoles, wireways, or shallow control cabinets. Cost-Effective Scaling: Allows users to add I/O points in small increments (8/8) without the expense of a full secondary network node. Universal Input Design: Reduces inventory requirements because a single spare part can handle both NPN and PNP sensor types. Ease of Installation: The integrated ribbon cable simplifies connection to the base block, and the DIN-rail mounting clip allows for tool-free installation. Simplified Diagnostics: Bright LED indicators for every I/O point and module status allow for rapid troubleshooting on the plant floor. Precautions (Important Notes) Expansion Limits: Each base block (e.g., 1790D) typically supports a maximum of three expansion modules. Do not exceed the power supply capacity of the base block when adding multiple modules. Ribbon Cable Care: The 7-cm ribbon cable is fragile. Avoid sharp bends or excessive tension during installation to prevent communication failures between blocks. Polarity Sensitive: While inputs are universal, the outputs are Sinking (V). Ensure your load is connected to the positive rail and that the module is switching the ground side. No Individual Isolation: While there is isolation between the I/O and the logic system, there is no isolation between the 8 individual input channels. Pollution Degree: This device is rated for Pollution Degree 2 environments. It must be installed in an enclosure (NEMA/IP rated) that protects it from conductive dust and moisture. Product Applications (Typical Use Cases) Material Handling: Controlling small conveyors, diverters, and sorting gates where space for electrical panels is limited. Operator Stations: Interfacing with pushbuttons, selector switches, and stack lights on localized control desks. Packaging Machinery: Managing high-speed sensors and small solenoid valves in compact assembly or wrapping machines. Automotive Skids: Providing distributed I/O for robotic welding or assembly cells where DeviceNet is used as the primary backbone. Retrofit Projects: Adding I/O to existing machines where the original control cabinet is already near maximum capacity.
