Active Digital Output Wiring; Passive Digital Output Wiring; Replacement Of Sensyflow Eco1 Measuring Systems - ABB FMT200-ECO2 Operating Instruction

Electrical connections

Active digital output wiring

The output current in the HIGH-mode must be limited to 1 mA when the active digital output is used (pas-
sive signal receiver). This is to ensure an output voltage U > 15 V.

Passive digital output wiring

Using the passive output (active signal receiver), the output current in the LOW-mode must be limited to
– 20 mA. This is to ensure an output voltage U < 2.5 V.

Replacement of Sensyflow eco1 measuring systems

Sensyflow eco1 and FMT200-ECO2 (Sensyflow eco2) are compatible. Using the appropriate electrical
adapter, FMT200-ECO2 can be connected to existing plants. As "interface" and "digital output" function-
ality is not available with Sensyflow eco1, there is no wiring within the adapter for these functions.
