Relay Outputs

The outputs can be connected to IS circuits with the following

maximum values:

Ui = 28V
Ii = 93mA
Pi = 653mW

The internal capacitance and inductance seen on these terminals is 0.1uF

and 0mH.

Flowmeter Input

Entity parameters on the flowmeter enable connection to a wide

range of approved sensors.

Input parameters are:

Ui = 24V
Ii = 20mA
Pi = 320mW

The internal capacitance and inductance seen on these terminals is 0.02uF

and 0mH.

Output parameters are:

Uo = 10.0V (open circuit)
Io = 9.0mA (short circuit)
Po = 23mW

Maximum allowed external capacitance is 20µF.
Maximum allowed external inductance is 1.5H.
