Feimu Technology has specially prepared an advanced high-performance analog input module for overseas industrial automation professionals. The Allen Bradley 1734-IE8CK is a POINT I/O thermocouple input module that connects seamlessly to Rockwell ControlLogix and CompactLogix systems through a POINT I/O adapter. This compact module can measure both milliamp signals and thermocouple temperatures, which can significantly simplify the wiring process on-site. As a professional supplier, we recommend this 8-channel module that supports multiple signal types and has diagnostic functions to all of you. Our aim is to enable you to easily handle high-precision data acquisition and temperature monitoring within limited installation space.
This Allen Bradley 1734-IE8CK circuit board is particularly designed to resist interference. Each input channel is equipped with an independent filtering circuit, just like installing a purifier for the signal, which filters out all external noise. The internal chips are all selected from industrial-grade high-precision components, with excellent temperature resistance. The contact pins on the back have been thickened and gold-plated, with outstanding hardness and conductivity. Even if the base station experiences significant vibrations, there is no need to worry about poor contact and data interruption.
Its casing is made of industrial-grade flame-retardant material, and the color is the unique gray-white of Rockwell. It looks very clean. The design on the front of the module is very simple. The most prominent feature is that the row of LED status indicator lights is very eye-catching. Whether there is a signal in the channel or there is a problem with the module itself, the illuminated state of the lights is clearly visible at a glance. The design of the base interface at the bottom is very ingenious, with a locking mechanism to prevent accidental insertion. When holding it in your hand, you can feel the tight grip. Overall, this thing is a high-quality component specifically designed for compact cabinets.

The 1734-IE8CK has built-in cold junction compensation. This is critical for accurate thermocouple temperature measurement.
Why CJC is needed:
How CJC works on the 1734-IE8CK:
Important CJC considerations:
Field issue example: A customer mounted a 1734-IE8CK directly above a power supply. The thermocouple readings were 5°C higher than actual. Cause: Heat from the power supply affected the CJC sensor. Fix: Moved the module away from the heat source. Readings returned to normal.
The Allen Bradley 1734-IE8CK uses a removable terminal block. Each channel has three terminals: TC+, TC-, and SHLD.
Thermocouple wiring:
mV signal wiring:
Cable type recommendations:
The 1734-IE8CK supports all common thermocouple types. Each type has a different temperature range and output characteristic.
| Thermocouple Type | Temperature Range (°C) | Typical Application |
|---|---|---|
| J | -210°C to 1200°C | Ovens, plastics, general industrial |
| K | -270°C to 1372°C | Furnaces, food processing, most common |
| T | -270°C to 400°C | Low-temperature measurement, cryogenics |
| E | -270°C to 1000°C | High accuracy, food processing |
| R | -50°C to 1768°C | High-temperature furnaces, glass industry |
| S | -50°C to 1768°C | High-temperature, laboratory standards |
| B | 0°C to 1820°C | Very high temperature, extreme heat applications |
| N | -270°C to 1300°C | High-temperature, better stability than K |
Configuration tip: In Studio 5000, select the correct thermocouple type for each channel. If the selected type does not match the sensor, the reading will be incorrect. Always verify the sensor type before commissioning.
The 1734-IE8CK has LED indicators for module and channel status. Use this guide for quick troubleshooting.
| LED | Status | Meaning | Action |
|---|---|---|---|
| Module Status | Green | Module powered and operating normally. | No action needed. |
| Module Status | Off | No power to module. | Check POINT I/O power. Check backplane connection. |
| Module Status | Red | Module fault or configuration error. | Check configuration in Studio 5000. Cycle power. |
| Channel LED (per channel) | Green | Channel configured and reading normal. | No action needed. |
| Channel LED | Off | Channel not configured or not used. | Configure channel in software. |
| Channel LED | Flashing (Green) | Input signal out of range. | Check sensor wiring. Check thermocouple continuity. |
| Channel LED | Red | Open circuit or short circuit detected. | Check thermocouple wiring. Check for broken sensor. |
Diagnostic functions:
The 1734-IE8CK requires software configuration in Studio 5000. Follow these steps to set up the module.
Configuration steps:
Configuration parameters:
Common configuration mistake: Selecting the wrong thermocouple type. If the selected type does not match the sensor, the reading will be incorrect. Verify the sensor type before configuration.
Allen Bradley 1734-IE8CK modules are commonly counterfeited. Use these checks to verify authenticity.
If the module shows incorrect temperature readings or the channel LEDs behave abnormally, suspect a counterfeit. Contact Feimu Technology with photos for verification.
