SIEMENS 6ES7331-7KF02-0AB0 SM331 Analog Input Module

-------------------------------------------------------------

ABOUT 6ES7331-7KF02-0AB0 :

You want to connect three analog inputs to your station. One of them should have a 2-wire current transducer and the other two should share a 4-wire current transducer. You need failure diagnostic capabilities and want two sensors to be able to trigger hardware interrupts. You have the analog input module SM331, AI8x12 Bit (order number 6ES7 331-7KF02-0AB0) available. The module is diagnostic and hardware interrupt capable and can process up to 8 analog inputs. The module is diagnostic and hardware interrupt capable and can process up to 8 analog inputs (e.g. 4- 20 mA; PT 100; thermocouple). 

The setup of the example station is divided into two steps. First, the setup of the power supply and the CPU is explained. After becoming acquainted with the analog module SM331, the mounting of it is described. 

Before you can use the analog input module SM331, you need a basic setup of general SIMATIC S7-300 components. The order of the mounting takes place from left to right:
● Power supply PS307
● CPU 315-2DP
● SM331
