8
Terminal
8 mA (positive, active output)
9 mA
10 mA (negative, passive output)
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 32 V is connected
the equipment may be damaged.
Terminal
6 mA (positive)
7 mA (negative)
This input is compatible with any device that provides a 4-20 mA output.
The impedance is 120 Ω. The input has a protection in order to limit the voltage applied to
the circuit.
