Siemens 6ES7288-1ST60-0AA1 SIMATIC S7-200 SMART CPU ST60 Controller

6ES7288-1ST60-0AA1 CPU ST60 is intended for machines that need a high onboard point count without immediately adding an I/O rack. It combines 36 digital inputs and 24 transistor outputs, giving 60 onboard I/O points for packaging lines, material handling and multi-station equipment.

All 24 channels are 24 V DC transistor outputs rated 0.5 A. They are not isolated relay contacts; verify group current, inrush current and suppression for solenoids, brakes and contactor coils, and add interposing relays where required.

Use a 20.4–28.8 V DC source and allow about 20 W power loss for the 6ES7288-1ST60-0AA1 CPU ST60. The body is approximately 175 × 100 × 81 mm and 528 g, so confirm DIN-rail length, ventilation and cable-bending space.

6ES7288-1ST60-0AA1 CPU ST60 provides 50 KB total program and data memory. This supports larger sequences, diagnostics, recipes and communication data than the 6ES7288-1ST30-0AA1 CPU ST30 or 6ES7288-1ST40-0AA1 CPU ST40, but retained data, alarm history and library blocks should still be included in the memory estimate.

The 6ES7288-1ST60-0AA1 CPU ST60 includes PROFINET 10/100 Mbps plus RS485. PROFINET can serve HMIs and controllers, while RS485 can be configured for PPI, Modbus RTU, USS or free-port communication.

Start with the final sensor and actuator list. Compatible S7-200 SMART expansion modules and a signal board can add functions, but reserve rail space, power budget and addressing capacity and verify the supported module combination.
