5.3 Digital Output Channel
The Digital Output Channel supports:
digital status output, host-controlled
digital status output, process-controlled
Via the digital inputs/outputs I/O 1 to I/O 6 on the datalogger
COMBILOG 1020
digital status can be output in digital form, ac-
cording to the configuration. A typical case of application would
be e.g. the local output of an acoustic or optical signal in case a
limiting value is exceeded or undershot by a measured value.
All outputs are open-collector.
The supply voltage can range from 10 up to 18 VDC. It has to be
either supplied externally or taken from the power supply of the
datalogger.
The status of the digital output can be scanned as 1/0 information
via bus.
With the host-controlled digital status output, the digital output is
set according to the status information received by the datalogger
via bus.
With the process-controlled output of status information the data-
logger monitors measured values, resp. sensor channels from
excess of default threshold values. The digital output is set if one
or several threshold conditions are fulfilled.
