1790D-TN0V2 Allen-Bradley 2 Channel Analog Voltage Output Module

1790D-TN0V2 Allen-Bradley 2 Channel Analog Voltage Output Module Overview

Key Technical Specifications for the 1790D-TN0V2

• Analog Outputs: The module features 2 single-ended, non-isolated output channels with 0-10V voltage range. Two red/green LED indicators clearly show the I/O status for each channel.
• Resolution & Accuracy: The Allen-Bradley 1790D-TN0V2 delivers 12-bit resolution (1/4096 max scale) with 2.44 mV/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 requires minimum external output load resistance of 1 KΩ with 0.5 Ω maximum output impedance.
• Insulation: The 1790D-TN0V2 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.

Wiring and Mechanical Specifications

• Terminal Block: It uses an M3.0 terminal block with a recommended screw torque of 7 lb-in maximum. Always use copper or copper-clad aluminum conductors for reliable connections.
• Expansion Capability: This analog base module accommodates a maximum of two discrete expansion modules, allowing system scalability for growing application needs.
• The Allen-Bradley 1790D-TN0V2 comes ready for DIN rail or panel mounting with a compact footprint for control cabinet efficiency.
• Always disconnect all power sources before wiring to ensure safety and prevent equipment damage during installation.
