Frequently asked questions

What is the difference between the 6ES5420-3BA11 and 6ES5420-4UA11 modules?

Both the 6ES5420-3BA11 and 6ES5420-4UA11 are Siemens SIMATIC S5 digital input modules with 32 non-isolated 24 V DC inputs in compact versions. The 'K' in 3BA11 and 'U' in 4UA11 often denote slight variations in form factor or internal revision, but both offer similar core functionality for non-isolated input acquisition.
