Module Type:
|
Low-Level Thermocouple Multiplexer
|
|
Number of Circuits:
|
16 channels
|
|
Isolation:
|
Each channel is fully isolated (channel-to-channel) and isolated from power and PM terminals.
|
Typical Application Scenarios
|
Process Control System (DCS): Used in industries such as oil refining, chemical engineering, and power generation for centralized acquisition of temperature data from multiple thermocouple points.
|
|
Remote/Distributed Nodes: Deployed in field terminal racks (FTAs) to centrally measure thermocouples and transmit data back to the control center.
|
|
Safety/Alarm System: Utilizes OTD (Out-of-Temperature Detection) functionality to monitor and alarm for channels exhibiting abnormal temperatures.
|
|
System Spare Parts/Replacements: Included in spare parts inventory as critical I/O modules for rapid replacement in case of module failure.

Features and Benefits
High-Density Thermocouple Acquisition
With 16 channels, this module can centrally manage multiple thermocouple (TC) signals, simplifying wiring and improving system monitoring capabilities.
Signal Isolation and Security
Each channel is well isolated from other channels and power supplies, reducing mutual interference and improving measurement reliability.
Over-Temperature Protection (OTD)
Equipped with over-temperature protection (OTD), a protection mechanism is triggered in case of abnormal temperatures, helping to protect the system and sensors.
Real-Time Scanning
A 1-second scan cycle enables rapid temperature sampling updates, suitable for dynamic process control.
Strong Adaptability to Industrial Environments
Conformal coating circuit board design + CE certification enhances its resistance to moisture and chemical gases.
Modular and Flexible Expansion
It can work with FTA architectures and other multiplexing/processing modules, offering high scalability.
All items are factory-new, sealed, and supported by PLC Autocontroller with same-day quotation and worldwide overnight delivery.
