The Siemens 6AG1593-0AA00-7AA0 is a conformal-coated cooling fan for SIPLUS S7-1500 CPUs. It runs on 24 V DC, draws 0.05 A (rated), and dissipates 1.7 W. The operating range spans -40 to +70 °C ambient, making it suitable for unconditioned enclosures or outdoor-adjacent installations.
Compatibility and mounting
This fan is designed specifically for the SIPLUS S7-1500 CPU 1518-4 variants: standard (6AG1518-4AP00-4AB0), F (6AG1518-4FP00-4AB0), and MFP (6AG1518-4AX00-4AC0). It connects via push-in terminals and occupies 170 x 119 x 54 mm (W x D x H). IP20 housing with reverse-polarity protection simplifies panel wiring.
Diagnostics and alarms
A red LED and a digital output (OK signal) report fan standstill or low speed. This allows the PLC or HMI to trigger a service call before the CPU overheats. The diagnostic function is enabled by default.
