Frequency / digital input indicator – totalizer
S311D is an indicator totalizer that accetpts universal opto isolated digital input. Admitted signal types are reed, npn (2 wires or 24 V), pnp (24 V), NAMUR, photoelectric, Hall, 24 V input, TTL, variable reluctance. Digital input signal frequency measurement starts from 0.00015 Hz to 10 kHz. S311D supports increment or decrement totalizing of the digital input signal. Also it’s possibile viewing the frequency measurement and/or totalized value. Programmable retransmission of the input value frequency is possibile by the isolated analog output (voltage or active/passive current). Retransmission of the totalized value by the isolated digital output (Open Collector). Totalizer value is saved on non-volatile memory.
