Ultra-slim Signal Converter

K3FP Series

Complete Lineup of Ultra-slim, High-
performance Converters for Every 
Application

• Ultra-slim 6.2-mm size.

Close mounting makes devices more compact.

• Easily wired and flexible with 8 terminal blocks.

• Multi-range I/O provides flexibility for the desired signal format.

• High-precision analog conversion with minimum current 

consumption.

• Reduced wiring through power supply connection with DIN rail 

bus connector (optional).
