6ES7288-3AQ04-0AA0 Siemens SIMATIC S7-200 SMART Analog I/O Module

Product parameters

Supply voltage: DC 24V (Allowable fluctuation range: -15% to +20%)

Current consumption: The module itself is approximately 60mA, and the maximum load current per channel is 100mA

Number of analog output channels: 4 (Each channel is independently designed and can be configured separately)

Output signal type: Supports two configurable types, namely 0/4-20mA (current signal) and 0-10V (voltage signal)

Resolution: 12 bits (Consistent output accuracy of current and voltage)

Output accuracy: 0.5% full range (at ambient temperature of 25℃)

Response time: ≤100μs (The time from digital signal update to analog output stabilization)

Load capacity: Minimum voltage output load is 1kΩ, and maximum current output load is 750Ω

Environmental adaptability: Operating temperature 0℃-55℃, storage temperature -40 ℃-70℃, protection grade IP20

Installation method: DIN rail installation in compliance with EN 50022 standard

Function

Multi-channel independent control: The 4 channels can be separately configured with signal types (current/voltage) without hardware adjustment, adapting to the requirements of different actuators.

Signal conversion and drive: Precisely convert the digital operation results of the S7-200 SMART CPU into analog signals to drive control valves, frequency converters and other equipment.

Fault protection and diagnosis: It is equipped with overload and short-circuit protection functions. When the load is abnormal, it feeds back fault signals to the CPU, facilitating quick problem identification.

Anti-interference design: Built-in EMC (Electromagnetic Compatibility) protection circuit to suppress electromagnetic interference in industrial sites and ensure stable output signals.

Application scenarios

In the field of process control: In chemical engineering, water treatment, and petroleum refining production lines, four channels can respectively control different flow valves and liquid level valves, and simultaneously adjust key parameters such as medium flow and storage tank liquid level.

In the field of intelligent manufacturing: In automated production lines and multi-axis machine tools, four servo drivers or proportional valves are driven to achieve synchronous speed or position regulation of multiple actuating components (such as robotic arms, conveyor belts, and spindles).

In the field of energy management: In photovoltaic power stations and energy storage systems, output signals control the power modules of four inverters, or in HVAC systems, simultaneously adjust the operating power of four fans and pumps to achieve energy conservation and system balance.
