The transmitter 7470 provides an economical means of converting digital data to analog signals, mA / V and transmitting them to four field instruments. Configuration is simple by MerkuWin program or the general purpose hand held programmer 6790. The transmitter uses the simple Nokeval SCL protocol. One serial data bus accepts 31 7470 transmitters or other serial instruments, that is 124 output channels. Typical applications are PC -based programs or PLC.
