Voltage/Current Analog Converter with 0-10 VDC / 4-20 mA Input and Output, 3-Way Galvanic Isolation, and K-BUS Connectivity
The K109UI is a three-port galvanically isolated converter designed for standard industrial current and voltage signals, featuring passive input and active output.
The analog-to-digital conversion provides 14-bit resolution on every input range. It also includes advanced functions such as programmable 50 Hz or 60 Hz mains rejection, additional filtering for reading stabilization, input and output scale inversion, programmable over-range input at 2.5% or 5%, square root extraction, and horizontal cylindrical tank linearization.
The module features an ultra-compact design, 35 mm DIN-rail mounting, bus power capability, quick spring-terminal connections, 3-way isolation, and field configurability through DIP switches.
