1790D-8BV8B Allen-Bradley 24V DC 8 Universal Input/8 Sourcing Output Base Module Overview

Detailed Input Specifications for 1790D-8BV8B

• Input Electrical Ratings: The 1790D-8BV8B operates at 24V DC nominal with a 9.6…28.8V DC range. Maximum on-state current reaches 8 mA per point at 28.8V DC. Off-state voltage measures 5V DC maximum for reliable signal distinction.
• Input Impedance & Indicators: Nominal input impedance sits at 4.8 KΩ for consistent performance. Eight green status LEDs show the real-time state of each input channel. The common configuration uses 8 points with 8 commons and features nonpolarity wiring.

Detailed Output Specifications for 1790D-8BV8B

• Output Electrical Ratings: Outputs operate at 24V DC nominal with a 10…28.8V DC range. Maximum output current rating is 0.5 A per output with 4.0 A maximum per common. On-state voltage drop stays below 0.5V DC max for efficient power delivery.
• Output Speed & Leakage: Minimum on-state current requirement is just 1 mA per channel. Maximum off-state leakage current is 0.5 mA for reliable off signals. Output signal delay measures 0.5 ms max for Off to On and 1.0 ms max for On to Off transitions.
• Output Indicators & Common: Eight green status indicators monitor each output channel in real time. The common type uses 8 points with 8 commons specifically for the 1790D-8BV8B configuration.

General Specifications and Power Requirements

• DeviceNet Power for Base Module: DeviceNet power supply requires 24V DC nominal with an 11…28.8V DC range. Maximum power dissipation reaches 1.2 W at 28.8V DC for energy efficiency.
• Field Power Specifications: Field power operates at 24V DC nominal with a 10…28.8V DC range. Power dissipation measures 6 mA at 28.8V DC per point for controlled consumption.
• Isolation and Wiring Details: Photocoupler isolation protects I/O circuits from logic with 1250V AC rms rating. DeviceNet to logic and DeviceNet power sections remain nonisolated. Wiring connects easily through the standard 37-pin D-shell connector.
