Active DC output
The mA analog output is HART-enabled if configured as a "4 ... 20 mA output".
Passive digital outputs, optocoupler
The passive digital outputs D
(see Abb. 18). They can be used as a binary contact as well as a pulse and frequency output.
The maximum current must be limited to 100 mA by means of series resistor R
As far as digital output 1 is concerned, terminals 16 (D
connected in accordance with the diagram shown above. Terminals 17 and 18 should be used
for digital output 2. The 24 V voltage at terminals 14 and 15 can be used as the voltage source
for the open-collector circuit.
Digital inputs
Digital inputs are used for switching over the characteristic curve within the device or for
controlling the totalizer.
A 24 V input signal can be defined as „"HIGH" or "LOW", depending on the polarity of D
D 2.

Important (Notice)
The connection area for the explosion-proof designs according to ATEX / GOST
Zone 0 / 1 / 21 and FM/CSA is described in Section 11, "Ex relevant specifications".
Important (Notice)
It is not possible to operate the Sensyflow FMT500-IG in multi-drop or burst modes.
