Feimu Technology, as an industrial automation component supplier with a long history, highly recommends Allen Bradley 1734 IR2K. This module is widely used in industrial temperature collection and process control fields, including heat treatment equipment, plastic molding machinery, food processing lines, packaging equipment, semiconductor manufacturing equipment, chemical process control, energy systems, and temperature monitoring in automated production lines. It can collect on-site RTD temperature signals and, in combination with the Allen Bradley PLC control system, achieve temperature monitoring, alarm handling, PID control, and automated process regulation. It is suitable for industrial environments with high requirements for measurement accuracy and system reliability.
The core advantages of Allen Bradley 1734 IR2K are: high-precision RTD temperature acquisition, miniaturized dual-channel design, compatibility with various types of sensors, strong adaptability to harsh environments, comprehensive diagnostic functions, and high compatibility with the Logix control platform.

This module supports: 2-wire RTD wiring, 3-wire RTD wiring, 4-wire RTD wiring.
Multiple wiring methods can reduce the influence of wire resistance on measurement results and improve the accuracy of long-distance temperature measurement.
Usually, it is configured through the following software: Studio 5000 Logix Designer, RSLogix 5000.
Configurable parameters include: RTD type selection; temperature unit; input filtering; alarm settings; channel diagnosis.
The Allen Bradley 1734 IR2K itself does not directly provide an Ethernet interface. It communicates with the network adapter through POINTBus, such as 1734 AENT, 1734 AENTR. Again through the EtherNet/IP connection with CompactLogix or ControlLogix PLC systems.
Fault phenomenon Possible cause
Abnormal temperature display Incorrect RTD type configuration
Large temperature fluctuation Loose wiring or line interference
Channel alarm RTD break or short circuit
No data from PLC POINTBus communication abnormal
Module status light abnormal Power supply or module failure
Large temperature deviation Line resistance influence or sensor aging
A qualified Allen Bradley 1734 IR2K should meet:
Model consistent with the order
No damage to appearance
Clear and complete labels
Normal POINTBus communication
Both thermocouple channels are normally collecting data
LED status normal
PLC can recognize normally
No hardware alarm or diagnostic faults
If any of the above problems occur, you can seek after-sales service. We will assist you in resolving the issues.
1734-IR2K supports 2-wire, 3-wire and 4-wire RTD connections. Each wiring method has different accuracy characteristics.
Both wires are connected to the input terminals.
The wiring is simple. The accuracy is the lowest. The resistance of the wires will be added to the reading.
It is suitable for short cables (less than 10 meters) or situations where accuracy is not critical.
One wire is connected to one terminal, and the other two wires are connected to the other terminal.
It compensates for the resistance of the compensating cable. The most common industrial method.
Recommended for most applications. For runs over 10 meters, use shielded cables.
Each terminal is connected to two wires.
The accuracy is the highest. It eliminates the error of wire resistance.
Used for high-precision applications or long cables (more than 30 meters).
Maximum wire resistance: 50Ω for each wire (3-wire and 4-wire).
Exceeding 50Ω will cause reading errors.
Use twisted shielded cables. The shielding layer is only grounded at the module end.
The Allen Bradley 1734 IR2K module is frequently counterfeited. Use the following checks to verify its authenticity.
Panel color: The genuine product uses a grayish-white color consistent with the POINT I/O series. Counterfeits often have different color codes or glossy surfaces.
Label quality: The genuine label is permanently printed and the model 1734-IR2K is clearly visible. Counterfeits often have blurry text or edges that are lifted.
Anti-corrosion coating: The PCB of the genuine product has an anti-corrosion coating to prevent moisture and corrosion. Counterfeits often lack this coating.
Bus connector: All pins must be gold-plated and straight. Counterfeits often use tin pins or have bent pins.
Module weight: The 1734-IR2K module of the genuine product weighs approximately 32 grams. Counterfeits often feel lighter.
