6ES7288-3AQ02-0AA0 Siemens SIMATIC S7-200 SMART Analog I/O Module

Product parameters

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

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

Number of analog output channels: 2 (independent channel design)

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

Resolution: 12 bits (Both current and voltage outputs are of 12-bit accuracy)

Output accuracy: 0.5% (within the full range, at an ambient temperature of 25℃)

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

Load capacity: Minimum load of 1kΩ for voltage output and maximum load of 750Ω for current output

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

Installation method: Standard DIN rail mounting (conforming to EN 50022 standard)

Function

Signal conversion: The digital control signals processed by the S7-200 SMART CPU are precisely converted into analog quantities (current or voltage) for driving external devices.

Channel configuration: Each output channel can independently set the signal type (current/voltage) without the need for additional hardware adjustments, offering high flexibility.

Fault diagnosis: Supports overload and short-circuit protection. When the output load is abnormal, the module will feed back a fault signal to the CPU, facilitating the system to troubleshoot the problem.

Anti-interference design: Built-in electromagnetic compatibility (EMC) protection circuit, which can effectively suppress electromagnetic interference in industrial sites and ensure the stability of output signals.

Application scenarios

In the field of process control: It is used to drive control valves, frequency converters and other equipment. For example, in chemical and water treatment production lines, it is used to control the opening degree of valves to regulate flow and liquid level, or to control the speed of motors to adjust the production rhythm.

In the field of intelligent manufacturing: In automated assembly lines and machine tool equipment, servo drivers or proportional valves are driven to precisely adjust the position of the robotic arm and the speed of the machine tool spindle.

In the field of energy and environment: In HVAC (Heating, Ventilation and Air Conditioning) systems and photovoltaic inverters, analog signals are output to control the speed of fans and the power of water pumps, or to adjust the output parameters of inverters, achieving energy conservation and stable operation.
