Pulse data logger AR407

universalUSBradio frequency

• data presentation and recording from up to 16 measuring channels, connected to APAR devices such as: • wireless sensors of AR43x series • any device with RS485 interface using MODBUS-RTU protocol • any device with Ethernet interface using MODBUS-TCP protocol • one wired temperature probe (AR182 or AR183) • available wireless sensors of AR43x series: • AR431/432 - temperature (one measurement channel) • AR435/436/437 - humidity and temperature (two channels) • AR433/434 - two-channel, ambient temperature and universal input: Pt100/Ni100/J/K/S/B/R/T/0÷20mA/4÷20mA/0÷10V/ 0÷60mV/0÷700Ω • versions with LCD display: AR432/434/436 • radio transmission in ISM 868MHz band, range up to 200 m in open space (or 400 m) - depending on the local radio propagation conditions: type and thickness of walls, doors, etc. • option of increasing the radio range up to 400 m by activating in sensors the function of measurement retransmission (the retransmission requires supplying sensors via the USB port, the network may include up to 3 re-transmitters) • 7 radio channels allowing the independent operation of 7 neighbouring AR407 sets with sensors • 4 alarm/control outputs with acoustic and visual signalling of the operational status and e-mail notification, setpoint of the output signal (in the range of 1÷100% pulse period) and option of assigning to any measurement channel • time control/timer for outputs, available options: continuous operation, periodic daily (hourly), or limited by date and time • recording of data in a standard text file located in the internal memory of the recorder (4GB) or an USB memory in a FAT system, with possibility to edit in spreadsheet software, e.g.
