Error
The analog output module creates a standardized signal of
0-20 mA or 4-20 mA.
The output signal is electrically isolated and will be transmitted with a
resolution of 12 bits.
“Current“ analog output modules use power derived from the field side
(loop powered).
The output channels have one common ground potential.
