Flow Meters SPI-73 flow meter 1 pulse input 1 relay (or OC) output power supply output 24V DC RS-485 / Modbus RTU SPI-73 are the flow meters designed to work in tandem with Typical applications the pulse flow transducers with coefficients ranging from 0,01 to 9999,99 pulses per litre. Wide range of total flow (up 1. Signalling minimal flow in refrigerating cycle, balance of refrigerating liquid. to 15 significant digits) enables flow volume control for a long time. The counters have 1 relay or OC output, which is programming depending on the actual instantaneous value of the flow. REL signalling - display of instantaneous and the total flow values, - password protection, - setting the volume units and the flow time, - settable delay time of control output: up to 99 sec. or min., - programmable decimal point position, - threshold hysteresis setting, - ACCESS option - easy threshold modification, - available with AC and DC power supply versions. flow transducer Examplary pin assignment Technical data Power supply: 19V 50V DC 16V 35V AC or 85 260V AC/DC, all separated RS-485 Power consumption: for 85 260V AC/DC and 16V 35V AC power supply: +24V +5% -10% Imax.100mA max. 4,5 VA 19V 50V DC power supply: max. 4,5 W GND DATA - Display: LED, red, 6 x 9 mm high + Ucz - DATA + Input: pulse galvanically insulated with contacts oscillation damping, max. frequency from 10 kHz L N 16 17 18 19 20 reset of totalizer counter: edge or level triggered, galvanically isolated 1 2 Accuracy of instantaneous flow values: selected in the range 0 0,00000 3 4 6 7 8 9 10 3 Instantaneous flow unit: l or m per second, minute or hour n.c. n.c. 85-260V 9 Total flow capacity: over 4 x 10 pulses (max. 15 significant digits) pulse reset COM AC/DC Total flow accuracy: selected in the range from 1 to 0,0001 input of totalizer 50/60Hz 3 counter Total flow unit: l or m 4W R1 Pulse waiting time: settable from 0,1 do 39,9 seconds Displayed values range: 0 999999 + decimal point Output: 1 relay 1A/250V AC (cos j=1) or the OC 30mA/30VDC/100mW Transducer power supply output: 24V DC +5%, -10% / max. 100 mA, stabilized, not Ordering insulated from communication interface Communication interface: RS-485, 8N1 and 8N2, 1200 bit/s 115200 bit/s, Modbus RTU (not galvanically insulated) SPI-73-141X-1-X-XX1 Data memory: non-volatile memory, EEPROM type options: Operating temperature: 0C +50C 00 : no options Storage temperature: -10C +70C 01 : IP 65 frame Protection class: IP 65 (front), available additional frame IP 65 for panel cut-out sealing IP 20 (case and connection clips) power supply: Case: board 3 : 24V AC/DC Case material: NORYL - GFN2S E1 4 : 85V - 260V AC/DC Case dimensions: 72 x 36 x 97 mm Panel cut-out dimensions: 66,5 x 32,5 mm type of outputs: Installation depth: min. 102 mm 1 : REL Board thickness: max. 5 mm 2 : OC V.10.10.1 3.2.1. 80-556 Gdask, Wielopole 7, POLAND, tel.
