6ES7288-3AE04-0AA0 PLC Siemens S7 200 Analog Input Module DC 24V

2. Key Selling Points

1. Analog Input Module for S7-200 SMART (4-Channel)l:Model AI04, a 4-channel analog input expansion module in the SIMATIC S7-200 SMART series—used to acquire standard analog signals from field sensors (e.g., temperature transmitters, pressure transducers, flow meters) for precise monitoring of continuous process variables
2. High-Accuracy Signal Acquisition:Equipped with a 12-bit A/D converter (resolution 1/4096), ensuring precise and reliable data capture.Basic measurement error < ±0.5%—meets accuracy requirements for general industrial control applications.
3. Open-Circuit & Range Error Diagnosis:Supports open-circuit (wire break) detection in current input mode—helps identify sensor or wiring faults early.Detects out-of-range conditions (e.g., 0 mA or 22 mA)—enables fault alarms via PLC logic or software, improving system reliability.
4. Galvanic Isolation for Strong Noise Immunity:Provides electrical isolation between analog inputs and PLC logic—prevents ground loops, surges, and EMI from affecting the CPU, ensuring stable and safe operation.
5. Seamless Integration with STEP 7-Micro/WIN SMART:Automatically recognized in programming software—supports hardware configuration, symbolic addressing, online monitoring, and parameterization.Wizard-based tools reduce engineering effort and accelerate commissioning.
6. Industrial-Grade, Wide Application Range:Operating temperature:Operating temperature: 0°C to +55°C.Complies with IEC 61131, EMC, and other industrial standards—widely used in compact automation systems, HVAC, water treatment, packaging machines, and production line monitoring.
