DN-843I-CT-20

Overview

The DN-843I-CT-20 is a three-channel current sense transformer designed for DIN rail mounting. It features a solid core closed design with an output range of +/- 10 Vpp. The device provides 1% accuracy of full scale range and includes 3000 VDC channel-to-channel isolation to prevent noise interference. It converts AC/DC voltage signals for data acquisition applications.

Feature Summary

• Three-channel configuration with solid core closed design
• Provides 3000 VDC intra-module and channel-to-channel isolation
• Outputs +/- 10 Vpp signal with 1% FSR accuracy

Applications

• Monitoring current from inverters in solar panels
• Monitoring current from wind turbines
• Industrial data acquisition systems requiring isolated current sensing

Procurement Notes

Verify the specific model suffix matches the required current rating, as variants exist for different amperage levels. Confirm that the solid core design accommodates the conductor size in your installation. Ensure the power supply requirements align with the system specifications before procurement.

Selection Notes

Select this model when high isolation voltage is critical to avoid noise interference between inputs and outputs. The three-channel layout suits applications requiring simultaneous monitoring of multiple phases or circuits. Consider the +/- 10 Vpp output compatibility with downstream analog input modules.

Part Context

This component belongs to ICP DAS's current sensor series, which includes variants like the DN-843I-CT-10 and DN-843I-CT-1. These sensors are typically used with analog input modules such as the I-7017R for comprehensive data acquisition setups in industrial environments.

Replacement Considerations

The DN-843I-CT-10 serves as a substitute for lower current requirements (10 A). The DN-843I-CT-1 is another variant for ±1 A applications. Verify that the replacement maintains the required isolation voltage and output signal range.
