Product Precautions
Siemens 6ES5451-4UA13 switches thirty-two 24 V DC field loads from a compact-U SIMATIC S5 output position, with each output rated at 0.5 A.
- 32 digital outputs
- 24 V DC load supply
- 0.5 A output rating
- Floating compact-U design
The module switches thirty-two configured loads in the installed SIMATIC S5 rack. Replacement preserves each output address, field conductor, group supply and floating-circuit boundary.
Important Notice: Prove every affected load under controlled commissioning after installing 6ES5451-4UA13; do not infer compatibility from the 451 family name alone.
