Steel and Metallurgy Industry
Installed on the cooling staves of blast furnaces or continuous casting machines to monitor the temperature distribution of the furnace wall,preventing furnace shell burn-through.
Power Generation Industry
Used to monitor the temperatures of large steam turbine bearings,generator stator windings,and real-time wall temperatures of boiler superheater tubes.
Pharmaceutical and Biochemical Industry
Used in fermentation tanks or high-pressure autoclaves for ultra-fine real-time temperature recording and over-temperature alarms, ensuring GMP standards for pharmaceutical production.
Automotive and Heat Treatment Industry
Used in metal quenching or annealing furnaces to control the heat treatment temperature curves of core components like gears,utilizing its independent setpoint alarm function.
Petrochemical and Refining Industry
Used in distillation columns or catalytic cracking reactors to precisely monitor the media temperature at different column sections, controlling the conversion rate of chemical reactions.
When using the HE693THM884G module,unused channels must be shorted to prevent noise interference from being introduced by floating channels.When connecting thermocouples,dedicated compensating wires must be used，ordinary copper wires are strictly prohibited to prevent inaccurate temperature measurements.During software configuration, ensure that the allocated 8%AI,8%AQ,and 16%I resources do not conflict with other modules. Finally,in environments with strong interference,shielded cables should be used and single-end grounding should be ensured to guarantee undistorted ultra-high resolution of 0.1℃.
FAQ View All FAQ
-
What is the HE693THM884G?It is a high-resolution thermocouple temperature input module manufactured by Horner APG, specifically designed for GE Fanuc's Series 90-30 PLC system.
-
How to use the HE693THM884G?Insert the module into a GE 90-30 PLC backplane, configure it within the programming software (e.g., Proficy Machine Edition or LM90), and wire the thermocouples to the front terminal block.
-
How many sensors can the HE693THM884G connect?The module supports up to 8 independent thermocouple inputs simultaneously.
-
What is the current product status of the HE693THM884G?For this legacy GE 90-30 module, request a new and unused unit with the exact installed reference. Availability is subject to an individual sourcing check; if that condition cannot be confirmed, review an approved replacement or migration with your engineering team.
-
Does the HE693THM884G require external power?It does not require an external 24V DC power supply. The electronic components of this module are powered directly by the GE 90-30 PLC baseboard (5V DC, power consumption approximately 100 mA).
