Model: 6ES7331-7KF02-0AB0 (SM   331)
Series: SIMATIC S7-300 (PM300) Analog Input Module
Function: Provides 8 analog inputs that can be configured for voltage, current, thermocouple, or resistance measurement, supports 9/12/14 bit resolution, has potential isolation, diagnostic, and alarm functions, and uses a 20 pin plug-in backplane connection.
Number of analog input channels: 8 (divided into 4 groups, each group can be independently programmed)
Resolution: Available in 9, 12, and 14 bits (with symbols)
Measurement types: voltage, current, resistance, thermocouple (temperature)
Input voltage range: Typical ± 5   V (programmable to ± 10   V, ± 20   V, etc.)
Input current: from load voltage L+(no-load) maximum 30 mA; from backplane 5 V DC maximum 50 mA
Power supply voltage: 24V DC (rated), with reverse polarity protection
Power loss: Typical 1   W (up to approximately 4.9   W, depending on resolution)
Potential isolation: isolation between the channel and the backplane bus; No isolation between channels
Diagnostic function: 6ES7331-7KF02-0AB0 supports fault accumulation indication (SF LED), limit alarm, and diagnostic information reading
Mechanical dimensions: Width 40mm x Height 125mm x Depth 117mm, Weight approximately 250g
Connection method: 20 pin plug-in front plug, compatible with S7-300 backplane bus.

Key Features：
Multi functional measurement: Each channel can be independently set as voltage, current, resistance, or thermocouple to meet various process signal acquisition requirements.
High resolution: up to 14 bit resolution, providing finer measurement accuracy.
Diagnosis and Alarm: 6ES7331-7KF02-0AB0 has built-in diagnostic function, which can read fault accumulation, limit alarm and other information through PLC to improve system reliability.
Potential isolation: Electrical isolation is achieved between the module and the backplane bus to prevent noise coupling and improve anti-interference ability.
Plug and play: 20 pin plug-in connector, supports hot plugging, easy to maintain and replace on site.
