The Siemens 6ES5451-7LA11 is a legacy digital output module from the SIMATIC S5 family (specifically designed for S5-115U/F PLC systems). It features 32 isolated, floating outputs operating at 24V DC / 0.5A. Because this is an obsolete hardware generation, it is typically sourced through industrial surplus or refurbished suppliers rather than direct factory channels.
Specifications:
- Module Type: Digital Output (32 DO)
- Rated Voltage: 24V DC
- Output Current: 0.5A per channel
- Platform: SIMATIC S5
