Overview
• Analog inputs for SIPLUS S7-1200
• With extremely short conversion times
• For connecting analog actuators and sensors without
additional amplifiers
• Even solves more complex automation tasks
• From +60°C to +70°C, max. 50% of the inputs can be
controlled simultaneously
Note:
SIPLUS extreme products are based on Siemens Industry
standard products. The contents listed here were taken from the
