Parallel output
This device contains the following outputs for the parallel interface.
The mapping of terminals to measured values for the parallel lines is as follows.
The parallel output specifications are as follows.
Note
Do not load the device beyond the maximum rating. Doing so will cause malfunctions.
Use a spark killer, surge absorber (AC or DC load), or diode (DC load) when opening or closing
the load to prevent electrical noise when connecting in parallel.
