Analog input modules

• Multi-function modules for current, voltage and temperature measurements
• Special, highly accurate modules for current and voltage measurements or temperature measurements

All modules automatically supply channel-specific and module-internal diagnostics data, except module 6ES7 331-1KF02-0AB0. With this module, a channel failure is detected by the SIMATIC PCS 7 analog driver block.

The channels of the analog input modules can be parameterized in groups independent of each other.

Analog output modules

• Modules with 12-bit resolution and different numbers of channels
• Highly accurate module with 15-bit resolution

The analog output modules can be parameterized in groups independent of each other, and automatically provide all channel-specific and module-internal diagnostics information.
