Technical Parameters
Number of Channels:
8-channel analog input.
Signal Type:
Voltage: ±10V, ±5V, ±2.5V, 0-10V, etc.
Current: 0/4-20mA, ±20mA
Resistance: Siemens 6ES7431-7KF10-0AB0 supports thermal resistor (RTD) or thermocouple (TC) input (need to be configured).
Resolution:
16 bits (high-precision conversion), supports multiple integration times to suppress interference.
Accuracy:
±0.1% FS (full scale), typical value.
Isolation:
Electrical isolation between channels to enhance anti-interference ability.
Communication interface:
Siemens 6ES7431-7KF10-0AB0 communicate with CPU via S7-400 backplane bus, support PROFIBUS-DP or PROFINET (need to be matched with corresponding interface module).
Power supply:
Backplane bus power supply (5V DC), external sensor power supply needs to be provided separately.
Operating temperature:
0°C to +60°C (industrial standard).
Diagnostic function:
Siemens 6ES7431-7KF10-0AB0 supports disconnection detection, over-range alarm, module fault indication, etc.
Product details
Modular design: can be flexibly expanded on S7-400 rack, supports hot swapping (redundant system needs to be configured).
Configuration method: parameter setting through STEP 7 or TIA Portal software.
LED status indication: The status of each channel can be displayed by LED lights (such as green/red indicator lights).
Compatibility: seamless integration with other modules of the S7-400 series (such as CPU, digital quantity modules).
Application areas
Process industry:
Pressure, temperature and flow monitoring in chemical, oil and gas industries.
Manufacturing:
Analog sensor signal acquisition on production lines (such as tension, position control).
Energy management:
Voltage/current monitoring in power systems.
Building automation:
Temperature and humidity sensor signal processing in air conditioning systems (HVAC).
Laboratory equipment:
High-precision measurement instrument data acquisition.
Feature summary
High precision: 16-bit resolution meets stringent industrial requirements.
Versatile: Supports multiple signal types and reduces module type requirements.
Reliability: Channel isolation and diagnostic functions improve system stability.
Flexibility: Suitable for distributed I/O systems (such as ET 200M).
