Overview
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).
