General information
The K-114 interface converter is used to convert a USB signal to a serial RS485 half-duplex signal, for connection
to any desired computer with a USB port. The K-114 converter and the connected transmitters are powered via the
USB connection. An external power supply unit can also be connected to power multiple instruments. The K-114
converter is preferred for use with KELLER products.
With the K-114 interface converter, you can…
…convert a USB signal to RS 485 (half-duplex)
…measure the applied signal voltage (0...12 VDC)
e.g. the output signal voltage from a pressure transmitter
…measure the power consumption of connected end consumers in the 0...40mA range
e.g. the power consumption of connected end consumers or
the power output signal from a pressure transmitter
The K-114 interface converter offers you…
…visual status and conguration displays (LED)
…electrical isolation between the computer and the converter
…diagnostic tools
