The 1790-T8BV8VX module from Allen Bradley falls within the CompactBlock LDX category and acts as an expansion module for flexible system integration. This device operates on a nominal supply voltage of 24 Volts DC, allowing for a supply voltage range between 11 and 28.8 Volts DC. Power efficiency is highlighted by a maximum power dissipation of 1.2 watts at the upper supply voltage limit.

In terms of input and output capabilities, this module supports 8 non-isolated inputs, which can function in either sinking or sourcing modes, along with 8 non-isolated sinking outputs. The nominal input ON-state voltage is set at 24 Volts DC, matching the nominal output ON-state voltage of the unit. When inactive, the acceptable input OFF-state voltage does not exceed 5 Volts DC, while the output leakage current during the OFF state is capped at 0.5 milliamps.

Additionally, it offers a nominal input impedance of 4.8 kiloohms, enhancing performance criteria. Each input and output has an associated green status indicator, ensuring instant visibility into the operational status. The built-in DeviceNet communication port further aids networking capabilities, allowing for streamlined connectivity within automation systems.

Mounting this module is straightforward due to the screw mount design, and it is rated for operation at altitudes up to 2,000 meters above sea level, making it suitable for both standard installations and elevated environments.
