Product Summary
Engineered for precision data acquisition, the 1734-IE8CK from Allen‑Bradley provides eight high‑density current inputs. It offers 0–20 mA and 4–20 mA ranges, 16‑bit resolution, and built‑in conformal coating for harsh environments. Absolute accuracy reaches 0.1% full scale at 77°F.
Expert Technical Evaluation & Performance Review
Exceptional Measurement Accuracy
The 1734-IE8CK achieves an absolute accuracy of 0.1% full scale at 77°F. This precision ensures reliable data for critical control loops. The module uses a delta‑sigma conversion type to deliver stable, low‑noise readings.
High‑Resolution Signal Capture
Each input channel provides 16‑bit resolution over a 0–21 mA range. This granularity captures subtle process variations. The data format outputs signed integers for seamless integration with Allen‑Bradley controllers.
Robust Environmental Protection
A conformal coating shields the board from moisture, dust, and corrosive gases. This feature extends service life in wet or chemically aggressive plants. Single‑ended, non‑isolated inputs simplify wiring while maintaining signal integrity.
Overload Handling and Input Impedance
The module withstands a maximum overload voltage of 28.8 V DC. Input impedance measures 60 ohms, matching standard current loop sensors. This prevents signal degradation and protects downstream electronics.
Application Fit for Process Industries
Eight current inputs suit multi‑point monitoring in chemical, water, and food processing. The 0–20 mA and 4–20 mA ranges cover most analog sensors. Engineers trust this module for high‑density, accurate data acquisition.
Product Procurement & Buyer Guide
Why Choose the 1734-IE8CK
Procurement managers value the high channel density in a compact Point I/O form factor. The conformal coating reduces the need for secondary protection enclosures. This lowers total installed cost and improves system reliability.
Compatibility and Integration
The 1734‑IE8CK mates directly with the 1734 Point I/O backplane and any compatible Allen‑Bradley controller. It supports both 0–20 mA and 4–20 mA current loops without need for external signal conditioners.
Key Specifications to Verify
Before ordering, confirm your system’s input range and accuracy requirements. The module delivers 16‑bit resolution and 0.1% full scale accuracy. Ensure your backplane provides adequate power and that environmental conditions meet the conformal coating rating.
Sourcing Considerations
Stock this module as a standard spare for multi‑channel analog input arrays. Its non‑isolated design simplifies wiring in grounded systems. Always consult the factory datasheet for exact environmental and installation parameters.
