KR80…… Suitable for the connection with a number of transmitters. For example, when 2 wire transmitter with
4 to 20mA output is used, up to thirty transmitters can be connected. In addition, the stability of the
output voltage is improved.KR81…… Lower-capacity and economical power unit. Especially, an economical system can be built for
small-scale instrumentation. When 2 wire transmitter with 4 to 20mA output is used, up to five
transmitters can be connected.

KR85…… Lower-capacity, small and lightweight power unit. When 2 wire transmitter is used, up to three
transmitters can be connected.

KR86…… Lower-capacity, small and lightweight power unit for transducer connection.
