Temperature Modules Selection Guide: Technical Criteria & Application Standards
Temperature Modules selection guide: technical parameters, mounting and compliance standards, and Schneider Electric, Delta Electronics, GMT comparison.
Temperature modules are analog input modules that connect thermocouples and resistance thermometers such as PT100 directly to the PLC and convert the sensor signal into a temperature value. They are used on furnace, extruder, plastic injection, drying and cooling lines to read temperature at multiple points without a separate transmitter and to set up a PID loop in the PLC. The category includes the Delta Electronics AX-5 series, DVP04PT-S and DVP04TC-S right-expansion modules, and GMT GXM-20UA and GXM-40UA universal-input modules; 2-channel and 4-channel models with PT100, PT1000, Ni100 and Ni1000 resistance thermometer inputs and J, K, R, S, T, E and N type thermocouple inputs are available. Select the module according to the sensor type (resistance thermometer or thermocouple), the channel count that covers the number of measuring points, the resolution and the PLC series it will be installed on. A module with resistance thermometer inputs is not a substitute for a module with thermocouple inputs; a resistance thermometer measures resistance, a thermocouple measures voltage at the millivolt level, and only universal-input models accept both. The Temperature Modules category on Welibaba includes 16 active models from leading manufacturers such as Schneider Electric, Delta Electronics, GMT.
Key Technical Parameters for Selecting Temperature Modules
To specify the right Temperature Modules model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| I/O Input | 2 Dijital Giriş, 2 kanal, 4 Dijital Giriş, 4 kanal | Verify against project schedule and load calculation |
| Series | Modicon Edge I/O NTS, Modicon M200, Modicon M221, Modicon M241 | Verify against project schedule and load calculation |
| Number of Analog Inputs | 2, 4, 6, 8 | Verify against project schedule and load calculation |
| Product Weight | 0.012 kg, 0.015 kg, 0.055 kg, 0.073 kg | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in PLC Input and Output Modules.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Analog Input Modules, Analog I/O Modules, Analog Output Modules.
