Allen-Bradley 1790-8BV8VX 24V DC 8 I/O DeviceNet Module

Allen-Bradley 1790-8BV8VX I/O Module: Compact DeviceNet Solution

Core Technical Specifications

• Input Configuration: The module features 8 non-isolated points that accept either sinking or sourcing signals.
• Input Voltage Range: It recognizes an on-state voltage from 9.6V DC minimum to 28.8V DC maximum, with 24V DC as nominal.
• Input Current: Each input point draws a maximum of 8 mA at the highest operating voltage.
• Output Configuration: The block provides 8 non-isolated sinking-type transistor outputs.
• Output Current Rating: Each output can handle up to 0.5 Amps, with a combined maximum of 4.0 Amps per common group.
• Switching Speed: Output response is fast with a delay of 0.5 ms max (Off to On) and 1.0 ms max (On to Off).

Electrical & Environmental Design

• Power Supply: The DeviceNet logic requires 24V DC nominal, operating from 11 to 28.8V DC.
• Isolation: The I/O circuits feature photocoupler isolation (1250V AC rms) from the internal logic for noise immunity.
• Power Consumption: Maximum power dissipation is 1.2 Watts for the base block logic.
• Connection: All field wiring connects through a standard 37-pin D-subminiature connector.
• Status Indicators: Eight green LEDs provide clear visual status for each input and output point.
