The 1734-IE2C module delivers precise current monitoring for distributed industrial systems. This Rockwell Automation component operates within the POINT I/O family. It converts analog signals into accurate digital values. Engineers use this module for reliable data acquisition.
Expert Technical Evaluation & Performance Review
This module features two single-ended, non-isolated current channels. Each channel accepts either 0-20 mA or 4-20 mA signals. The internal Analog to Digital Converter uses Delta-Sigma conversion. This provides a resolution of 16 bits across a 0 to 21 mA range. You get a granularity of 0.32 μA per count.
The 1734-IE2C boasts an absolute accuracy of 0.1% Full Scale at 25 degrees Celsius. Its accuracy drift remains low at only 30 ppm per degree Celsius. This ensures stable performance across varying plant temperatures. The module stores converted data in a Signed Integer format. This design guarantees precise and repeatable process control.
You can adjust the input step response per channel. The default notch filter is 60 Hz with a 70 ms response. For higher noise environments, a 50 Hz notch offers 80 ms filtering. Faster settings include a 250 Hz notch at 16 ms. The 500 Hz notch provides the fastest response at 8 ms. The module update rate mirrors these filter settings for seamless data flow.
Detailed Procurement & Application Guide
Engineers should verify the terminal base compatibility before purchase. The 1734-IE2C requires a 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS base. You must set the module keyswitch to position 3 during installation. This module supports both horizontal and vertical DIN rail mounting. Its compact dimensions are 56 x 12 x 75.5 mm, weighing only 0.036 kg.
This module draws 75 mA from a 5V DC bus. It dissipates a maximum power of 0.6 W at 28.8V DC. The unit uses an external power supply from 10 to 28.8 Volts DC. It has a continuous isolation voltage of 50 Volts DC. The 1734-IE2C is also rated for a dielectric withstand of 2550 Volts DC for 60 seconds.
For wiring, use solid or stranded copper wire from 22 to 14 AWG. The wire insulation must be rated for 167 degrees Fahrenheit. The module features built-in overload protection up to 28.8 Volts DC. This protects the channel from potential wiring faults. The 1734-IE2C is compatible with ControlNet, DeviceNet, and EtherNet/IP networks.
