1790D-TN0C2 Allen-Bradley 2 Channel Analog Current Output Module

1790D-TN0C2 Allen-Bradley 2 Channel Analog Current Output Module Overview

Key Technical Specifications for the 1790D-TN0C2

• Analog Outputs: The module features 2 single-ended, non-isolated output channels with 0-20 mA current range. Two red/green LED indicators clearly show the I/O status for each channel.
• Resolution & Accuracy: The Allen-Bradley 1790D-TN0C2 delivers 12-bit resolution (1/4096 max scale) with 4.88 µA/bit. It maintains 0.2% full scale overall accuracy across 0-55 °C operating temperatures.
• Data Format: It uses binary data format ranging from 0000 to 0fff (max scale) for straightforward programming and integration. The module requires no field calibration, simplifying installation.
• Performance: This output module offers a fast 2 ms conversion time per channel. It supports external output load resistance up to 600 Ω maximum for versatile field device connectivity.
• Insulation: The 1790D-TN0C2 provides 20 MΩ minimum insulation resistance at 250V dc between insulated circuits for reliable operation.

Power Requirements and Isolation Specifications

• DeviceNet Power: The base module requires a separate 24V DC nom supply (range 11-28.8V DC) for its internal logic. Maximum power dissipation is 1.2W at 28.8V DC.
• Field Power: You must supply an external 24V DC nom power source (range 21.6-26.4V DC) for the analog output circuits. Maximum power dissipation is 1.5W at 26.4V DC.
• Isolation Features: The module includes photocoupler isolation between I/O and logic, with type test isolation voltage of 1250V AC rms for 60 seconds. DeviceNet to logic and field power remain non-isolated.
