Allen-Bradley 1790D-8BV8B Universal I/O Module Product Introduction

Input Specifications & Capabilities

  • The 1790D-8BV8B provides 8 universal input points that support both sinking and sourcing configurations.
  • Input on-state voltage ranges from 9.6V DC minimum to 28.8V DC maximum, with 24V DC nominal.
  • Each input channel draws a maximum of 8 mA at 28.8V DC during operation.
  • The module features a nominal input impedance of 4.8 KΩ for reliable signal detection.
  • All eight input points have independent commons (8 points/8 COM) for wiring flexibility.

Output Specifications & Performance

  • The module includes 8 sourcing output points for driving various loads.
  • Output on-state voltage ranges from 10V DC minimum to 28.8V DC maximum, with 24V DC nominal.
  • Each output supports 0.5A maximum current per point with a 4.0A maximum per common group.
  • Fast response times include 0.5 ms maximum off-to-on delay and 1.0 ms maximum on-to-off delay.
  • The module maintains low off-state leakage current of 0.5 mA maximum for energy efficiency.

Power Requirements & Isolation

  • DeviceNet power operates at 24V DC nominal (11-28.8V DC range) with 1.2W maximum power dissipation.
  • Field power supply requires 10-28.8V DC with 6 mA per point consumption at 28.8V DC.
  • Photocoupler isolation provides 1250V AC RMS protection between I/O circuits and internal logic.
  • The module uses a standard 37-pin D-shell connector for all wiring connections.
  • Each I/O point features individual green LED status indicators for immediate diagnostics.
