Technical Parameter TableSiemens converter 6SE6440-2UD42-0GA1*

Parameter	Description
Module Type	Analog Input Module (AI Module), supporting thermocouple signal input.
Number of Channels	8 analog input channels (dedicated for thermocouples).
Input Signal Type	Supports various thermocouple types:
Input Signal Type	- B, E, J, K, L, N, R, S, T, PL200, Ni1000, etc.
Resolution	16 bits (signed integer, including the sign bit).
Accuracy	- Typical error: ±0.1% (for Type K thermocouple at 25°C);
Accuracy	- Cold junction compensation error: ±0.5°C.
Input Range	Depends on the thermocouple type (for example: for Type K, it is -200°C ~ +1350°C; for Type J, it is -210°C ~ +1200°C).
Open Circuit Detection	Supports channel-level open circuit detection, and outputs the upper limit value when there is an open circuit (can be configured as upper/lower overflow or a specified value).
Cold Junction Compensation	The module has a built-in temperature sensor and automatically performs cold junction compensation (compensation range: 0°C ~ 55°C).
Power Supply Voltage	DC 24V (powered through the PLC backplane bus, no additional power module is required).
Current Consumption	Approximately 80mA (powered from the backplane bus).
Protection Level	IP20 (needs to be installed in the control cabinet, in line with industrial environment standards).
Installation Method	DIN rail installation (35mm), supports horizontal or vertical installation, and is directly connected to the S7-1200 host.
Communication Interface	Communicates with the CPU through the S7-1200 backplane bus, supporting real-time data exchange.
Configuration Tool	TIA Portal V13 and above versions. The thermocouple type and input range need to be configured in the hardware configuration.
Diagnostic Function	- Channel-level fault diagnosis (open circuit, out-of-limit, configuration error);
Diagnostic Function	- LED status indicator lights (power supply, fault).
Environmental Conditions	- Operating temperature: 0°C ~ 60°C;
	- Storage temperature: -40°C ~ +85°C;
	- Relative humidity: 5% ~ 95% (no condensation).
Dimensions (W×H×D)	35mm × 100mm × 110mm (compact design, saving control cabinet space).
Weight	Approximately 190g.

Main FunctionsSiemens V20 Inverter 15KW of Model 6SL3210-5BE31-5UV0

1. **High-precision Measurement**: 16-bit resolution supports high-precision temperature collection, suitable for industrial temperature monitoring scenarios (such as heating furnaces, pipeline temperature measurement).Chint converters (NVF2G-18.5/TS4 or NVF2G-18.5/PS4

2. **Compatibility with Multiple Types**: Supports mainstream thermocouple types, no additional signal conversion module is required, simplifying the system design.

3. **Intelligent Diagnosis**: Real-time detection of faults such as open circuits and signal out-of-limit, and feedback of status through LED and diagnostic buffer.

4. **Quick Configuration**: Intuitively configure input parameters through TIA Portal, and support firmware update to expand functions.
