AR715
AR715 Flow Meter/Pulse Counter
✔ Configurable measurement mode:
- flow and balance measurement
- pulse counter
- incremental encoder (measurement of rotational speed, rotation angle, displacement)
- dispenser (dosing and simultaneous balance counting)
- frequency measurement
- remote display via RS485, MODBUS-RTU protocol, slave
✔ maximum measurement frequency:
- 10 kHz - for flow, frequency, rotational speed
- 30 kHz - for counter with PNP output
- 100 kHz - for a counter with NPN output
✔ balance capacity 2x10^9 [units] with sign (-1999999999 ÷ 1999999999), 10 digits when the step position is 0
✔ universal pulse inputs (IN1, IN2) supporting flow meters, presence sensors, and encoders with the following outputs:
- NPN open-collector
- PNP open-collector
- contact (reed, mechanical)
✔ additional inputs:
- S - start/stop counting (counting enable)
- R - counter/balance reset
- B - binary input with programmable function
✔ 2 relay outputs or, optionally, SSRs with programmable operating characteristics
✔ analog output 0/4–20 mA or 0/2–10 V (alarm, relay)
✔ built-in power supply for flow meters, encoders, and other 24 V / 50 mA sensors
✔ four-color LED display with adjustable brightness
✔ access to configuration parameters with or without password protection
✔ programming via a 4-button membrane keypad or digital interface
✔ programmable function key F and binary input for changing operating modes: keypad lock, unconditional manual mode for outputs, hold function for flow measurement (HOLD), start/stop of the dosing unit
✔ programmable communication options, alarms, and other configuration parameters
✔ methods of parameter configuration:
- via the IP65 membrane keypad located on the front panel of the device
- via the RS485 port or PRG (AR956/955 programmer) and the free ARSOFT-CFG software (Windows Vista/7/8/10), MODBUS-RTU
✔ software and a programmer enabling the display of measured values and quick configuration of individual or predefined parameter sets previously saved on a computer for reuse, for example in other devices of the same type (configuration duplication)
✔ high accuracy and resistance to interference in industrial environments
✔ 96x48 mm panel-mount housing, IP65 from the front (with an accessory gasket or other, IP54 without a gasket), IP20 from the connector side
