Option OR:
:
A mechanical relay output according the functions R1 and R2 is available with this option.
Max. switch power 240V-0,5A per output. (Requires power supply option PF / PM).
Terminal 07-08 POWER SUPPLY F131-P - output loop powered:
Connect an external power supply of 8-24 volts AC or 8-30VDC to these terminals or a 4-20mA loop.
For a DC supply: connect the "
-
" to terminal 7 and the "
+
" to terminal 8. When power is applied to
these terminals, the (optional) internal battery will be disabled / enabled automatically to extend the
battery life time. (Only valid for standard passive output).
Terminal 07-08 analog output (passive) (SETUP 6) :
A 4-20mA current-sinking signal proportional to the flowrate is available as standard.
A DC power supply should be connected to terminal 07 and 08, the current is then regulated by unit.
This DC supply is also used to power the unit (output loop-powered). When a power supply is
connected but the output is disabled, a 3.5mA signal will be generated.
Max. driving capacity 1000 Ohm.
