The analog output is galvanically isolated. It can be either active (which means that the
receiving device must be passive) or passive (which means that the receiver must supply the
power for the current loop). It is recommended to use a receptor with an input resistance of
less than 700 Ω to guarantee correct operation.
The configuration of the analog output mode (active or passive) is done by means of the
connection to the terminal strip. For active mode, terminals 8 and 9 are connected. For
passive mode, terminals 9 and 10 are connected.
NOTE: The analog output has a protection against reversed polarity. Due to another
protection against over voltages, if a loop supply voltage of more than 36 V is connected the
equipment may be damaged.
