Compatible Replacement & Equivalent Models
The following modules are functionally compatible or serve as direct/near-direct replacements for the 6ES7288-3AR02-0AA0. Always verify electrical and mechanical compatibility before substitution.
| Model | Brand | Channels | Output Type | Compatibility Notes |
|---|---|---|---|---|
| 6ES7288-3AQ02-0AA0 | Siemens | 2 AQ | Voltage / Current | Same series, verify firmware version |
| 6ES7288-3AQ04-0AA0 | Siemens | 4 AQ | Voltage / Current | Expanded channel count; pin-compatible bus |
| FX2N-2DA | Mitsubishi | 2 AQ | Voltage / Current | Cross-brand; requires wiring adaptation |

| XM0-2DA | Kinco | 2 AQ | Voltage / Current | Budget alternative; verify signal accuracy |
Note: Cross-brand replacements require independent wiring and software configuration. Konmask recommends using original Siemens modules for mission-critical applications.
Why Choose the Original Model
- Seamless Integration: Plug-and-play expansion with S7-200 SMART CPUs via the proprietary expansion bus — no additional configuration required.
- High Accuracy: 12-bit resolution ensures precise analog output for demanding process control loops.
- Dual Output Mode: Supports both voltage (±10 V) and current (0/4–20 mA) output on each channel, selectable per channel.
- Compact Form Factor: Slim DIN-rail design minimizes panel space while maintaining full industrial-grade performance.
- Proven Reliability: Backed by Siemens’ global quality standards, CE/UL certifications, and long-term spare parts availability.
- STEP 7-Micro/WIN SMART Support: Fully supported by Siemens’ official programming software with pre-built function blocks.
Typical Applications
- Variable frequency drive (VFD) speed reference signal output
- Proportional valve and actuator control in hydraulic/pneumatic systems
- Temperature setpoint transmission to PID controllers
- Flow and pressure regulation in process industries

Maximum of 6 expansion modules per S7-200 SMART system. Analog modules consume additional 5 V DC bus current — verify total bus current budget before configuration.
Selection Guide
Use the following criteria to confirm the 6ES7288-3AR02-0AA0 is the right module for your application, or to identify a suitable alternative:
- Channel Count: Need more than 2 analog outputs? Consider the 4-channel 6ES7288-3AQ04-0AA0.
- Signal Type: Confirm whether your field device requires voltage (±10 V) or current (4–20 mA) — both are supported on this module.
- CPU Compatibility: Verify your CPU model supports expansion modules (CR-series CPUs do not).
- Bus Current Budget: Each analog module draws from the 5 V expansion bus. Check total current consumption against your CPU’s rated output.
- Mixed I/O: If you need both analog input and output, consider pairing with the 6ES7288-3AM06-0AA0 (4AI/2AQ combo module) to reduce module count.
- Environment: For harsh environments (dust, vibration), confirm IP20 rating is sufficient or add appropriate enclosure protection.

Replacement & Compatibility FAQ
Q: Can I use 6ES7288-3AR02-0AA0 with an S7-200 (classic) CPU?
A: No. This module is designed exclusively for the S7-200 SMART series. It is not compatible with the legacy S7-200 (6ES7 2xx-xxxx-xxxx classic) expansion bus.
Q: Is the output voltage and current selectable per channel?
A: Yes. Each channel can be independently configured for voltage or current output via STEP 7-Micro/WIN SMART software.
Q: What happens to the analog output if the CPU stops or faults?
A: Outputs default to 0 V / 0 mA (or a user-defined substitute value) upon CPU STOP or fault, depending on software configuration.
Q: Can I stack multiple 6ES7288-3AR02-0AA0 modules?
A: Yes, up to the system limit of 6 expansion modules total per CPU. Monitor total 5 V bus current consumption.
Q: Do you provide a certificate of conformity (CoC) or test report?
A: Yes, available upon request for orders of 3 or more units. Contact support@konmask.com.
