Compatible Replacement & Equivalent Models
The table below lists direct replacements and functional equivalents for the 6ES7288-1SR60-0AA0, suitable for retrofit, spare-part sourcing, or cross-brand substitution:
- SIEMENS 6ES7288-1ST60-0AA0 — CPU ST60, same I/O count, transistor (sourcing) output; drop-in replacement for DC load applications
- SIEMENS 6ES7288-1SR40-0AA0 — CPU SR40, 40 I/O, relay output; downgrade option when full 60-point capacity is not required
- SIEMENS 6ES7288-1SR30-0AA0 — CPU SR30, 30 I/O, relay output; compact alternative for smaller panels
- SIEMENS 6ES7288-1SR20-0AA0 — CPU SR20, 20 I/O; entry-level S7-200 SMART for minimal I/O needs
- Mitsubishi FX3U-64MR/ES — 64 I/O, relay output, AC power; cross-brand functional equivalent with similar capacity
- Mitsubishi FX5U-64MR/ES — Next-generation Mitsubishi PLC; higher performance cross-brand alternative
- Omron CP1H-X40DR-A — 40 I/O, relay, AC; comparable compact PLC for cross-brand evaluation
Note: Cross-brand replacements require program re-engineering. Always verify I/O voltage levels, communication protocols, and software compatibility before substitution.
Why Choose the Original Model
- Seamless STEP 7-Micro/WIN SMART integration — no re-programming required when replacing like-for-like
- Proven reliability in harsh industrial environments with wide AC input range (85–264 V)
- Relay outputs provide galvanic isolation and compatibility with AC/DC loads without additional interface relays
- Largest I/O in the S7-200 SMART CPU range — eliminates the need for additional expansion in many applications
- Integrated Ethernet port enables direct PC programming, HMI connection, and peer-to-peer communication without extra modules
- Long-term SIEMENS support and global spare-parts availability
Typical Applications
- Packaging and labeling machines
- Conveyor and material handling systems
- HVAC and building automation panels
- Water treatment and pump control stations
- OEM machine control with mixed AC/DC loads

- Signal Boards: Supports SB AQ01, SB DT04, SB CM01 (RS-232/RS-485)
- HMI: SIMATIC Smart Line panels, KTP series via Ethernet or RS-485
- SCADA/DCS: Modbus RTU/TCP, S7 protocol via Ethernet
- Programming Software: STEP 7-Micro/WIN SMART V2.4 and above
- Power Supply: Requires external 24 V DC sensor supply for input circuits
Selection Guide
Use the following criteria to confirm the 6ES7288-1SR60-0AA0 is the right choice, or to identify the best alternative:
- I/O Count: Need ≤ 60 onboard points? → SR60. Need fewer? → SR40 / SR30 / SR20.
- Output Type: Relay (AC/DC loads, galvanic isolation) → SR60. Transistor (high-speed, DC only) → ST60.
- Power Supply: AC mains available → SR60 (AC). DC-only panel → consider ST60 (DC/DC/Transistor).
- Communication: Ethernet + RS-485 standard on all S7-200 SMART CPUs — no additional module needed.
- Expansion Needed: Up to 6 EM modules can be added; max 188 I/O total.
- Cross-Brand: If migrating from Mitsubishi FX3U or Omron CP1H, functional mapping is feasible but requires full program re-development.

Replacement & Compatibility FAQ
Q: Can the 6ES7288-1ST60-0AA0 (ST60) directly replace the SR60?
A: Yes, for DC load applications. The ST60 uses transistor (sourcing) outputs instead of relay outputs. If your loads are AC or require galvanic isolation, retain the SR60.
Q: Is the 6ES7288-1SR60-0AA0 still in production?
A: The S7-200 SMART series remains in active production and sale as of 2026. It is not discontinued.
Q: Can I use a Mitsubishi FX3U-64MR as a drop-in replacement?
A: No. Cross-brand replacement requires full program re-development in GX Works2/3. Hardware wiring must also be re-verified.
Q: What is the maximum number of expansion modules?
A: Up to 6 EM expansion modules, reaching a maximum of 188 digital I/O points.
Q: Does the SR60 support motion control?
A: Relay output CPUs do not natively output high-speed pulses. Add an SB DT04 signal board for pulse output capability.
Q: What HMIs are compatible?
A: SIMATIC Smart Line panels (SMART 700 IE, SMART 1000 IE) and KTP series panels connect via Ethernet or RS-485.
