Product Details
Product Overview
The 1734sc-IE4CH serves as a specialized high-density analog input module for the Allen-Bradley POINT I/O platform. It provides four channels of 4-20mA analog input while simultaneously enabling HART (Highway Addressable Remote Transducer) protocol communication. This module allows engineers to extract secondary process variables and device diagnostics directly from smart field instruments without additional hardware. We supply this module as 100% Brand New and factory-original, ensuring full hardware integrity for your mission-critical process loops.

Engineering Advantages
-
HART Data Integration: The 1734sc-IE4CH captures advanced diagnostic data and multi-variable information from smart transmitters. This capability enables predictive maintenance by monitoring device health and secondary process parameters (TV/FV) over the existing 4-20mA wiring.
-
High-Precision Signal Processing: The 16-bit resolution ensures granular data acquisition for sensitive applications. It detects minute fluctuations in process variables, allowing the controller to execute more precise adjustments in closed-loop systems.
-
Enhanced Channel Isolation: The 10 VDC channel-to-channel isolation minimizes ground loop interference and prevents signal "crosstalk" between adjacent inputs. This ensures that a fault on one instrument does not corrupt the data from the remaining three channels.
-
Compact Single-Slot Design: The module fits into a standard POINT I/O base. It provides four HART-enabled channels in a single slot width, maximizing I/O density in small junction boxes and reducing overall cabinet hardware costs.
FAQs
-
Does the 1734sc-IE4CH require a specific terminal base?
The module installs into any standard 1734-TB or 1734-TBS terminal base. Ensure the base remains correctly keyed to the analog input module to prevent incorrect module insertion.
-
Can I use this module for standard 4-20mA signals without HART?
Yes. The module functions as a high-precision 16-bit analog input module for standard 4-20mA transmitters. You can enable or disable the HART communication features via the software configuration.
-
How does the 1734sc-IE4CH handle field-side power?
The module draws backplane power for its internal logic, but you must provide field-side power to your 4-20mA transmitters. Verify that your power supply maintains the required voltage for the 250 Ohm typical impedance of each channel.
-
What software environment supports the HART variables?
You configure the 1734sc-IE4CH using Studio 5000 Logix Designer. The HART variables (PV, SV, TV, FV) map directly into the controller's tag database for easy access in your control logic or HMI.
