4.3.3 Current input

An external transmitter, e.g. temperature or pressure transmitter, can be connected to
terminals I1+ and I2-. The 4...20 mA current signal is converted to the corresponding
temperature or pressure value in the signal converter.

1 Power supply for the signal converter
2 Power supply for an external temperature or pressure transmitter
The current input can be configured in menu C1.5. Depending on the configuration of the current
input, the sources for temperature and/or pressure value have to be adjusted in menu C1.6 or
C1.7.

4.3.4 Binary output

Unless otherwise ordered, the binary output is inactive by default and must thus be activated and
configured as limit switch output, pulse output, frequency output or status output in menu C2.2
prior to first use. The binary output is electrically separated from the current output and must be
supplied with power separately.
