The set of indicators-totalizers S311D counters are a family of digital LED indicators with universal opto-isolated digital input of type: Reed, NPN (2-wire or 24V), PNP (24V), NAMUR, Photoelectric, Hall, 24V input, TTL, to variable reluctance.
The measurement range of the frequency of the input digital signal from 0.00015 Hz to 10 kHz.
The digital indicators S311D allow you to increase or decrease the aggregation of the digital input signal, the display of frequency measurement and / or the totalizer value and retransmission programmable frequency of the input signal on isolated analog output voltage or current active / passive.
It is also available retransmission of the totalized value of digital output isolated Open Collector type.
The totalizer value is saved in non-volatile memory.
