Engineering Advantages
The 1734-IR2E solves specific thermal measurement challenges in high-density control cabinets:
-
Superior Signal Precision: The 16-bit resolution detects minute resistance changes, allowing the PLC to monitor temperature fluctuations with laboratory-grade accuracy. This precision prevents overshoot in sensitive heating or cooling applications.
-
Effective Noise Rejection: Digital filtering and 50V continuous isolation protect the low-voltage RTD signals from electromagnetic interference (EMI) generated by nearby variable frequency drives (VFDs) and motor starters.
-
Simplified Mechanical Configuration: The hardware utilizes a physical keyswitch at position 6. This mechanical lock prevents the insertion of incorrect module types into the terminal base, shielding the system from accidental voltage damage during maintenance.
-
Thermal Efficiency: The module dissipates only 1.0 Watt of power. This low thermal footprint prevents heat buildup in compact distributed I/O enclosures, extending the lifespan of adjacent electronic components.
FAQs
-
Which RTD sensor types does the 1734-IR2E support?
This module supports standard 100-ohm Platinum (Pt) RTDs and various other resistance-based sensors. You must configure the specific sensor type (e.g., Pt 385 or Pt 3916) within the Studio 5000 or RSLogix 5000 software environment to ensure correct scaling.
-
Does this module require a specific terminal base?
The 1734-IR2E installs into 1734-TB, 1734-TBS, or 1734-TOP terminal bases. Ensure the base is properly grounded to the DIN rail to maximize the noise rejection capabilities of the 16-bit converter.
-
How does the "Signed Integer" data format work for temperature?
The module converts the analog resistance into a signed integer value. The PLC then scales this integer into engineering units (Celsius or Fahrenheit) based on the configuration profiles, providing direct temperature readouts to the HMI.
-
What happens if an RTD wire breaks during operation?
The 1734-IR2E features integrated open-circuit detection. When a wire breaks or a sensor fails, the module flags a diagnostic error to the PLC, allowing the system to trigger a safe-state shutdown or alarm immediately.

Tech & Buying Guide
Redundant Automation Systems: Ensuring Continuous Uptime in Critical Control Infrastructure
System reliability directly determines operational profitability across high stakes process industries. Modern industrial automation platforms must eliminate single points of failure to prevent catastrophic shutdowns. Deploying fault tolerant architecture safeguards complex facilities against unexpected hardware glitches, network disruptions, and maintenance outages.
Understanding Types of Noise in Electronic Circuits and Control Systems
Signal integrity directly determines measurement accuracy and loop stability across industrial automation environments. Electronic noise introduces unwanted stochastic interference into analog loops, sensor feedback lines, and digital fieldbus networks. Understanding how intrinsic electronic noise and external electromagnetic interference manifest allows control engineers to optimize signal conditioning and shield sensitive instrumentation effectively.
Why 24V DC Power Supplies Standardize Modern Industrial Automation
Industrial control cabinets worldwide rely on 24V DC as the universal power standard for field instrumentation, sensors, and controllers. Walk into any manufacturing plant, and you will find PLCs, human-machine interfaces (HMIs), and smart actuators running on extra-low voltage DC. Standardizing on 24V DC enhances operational safety, lowers cabinet footprint, and maintains steady control performance across factory networks.
