3. GENERAL CHARACTERISTICS OF THE MULTI-CHANNEL RECORDER
meas rement and recording of temperat re from thermoresistance sensors and thermoco ples and other
physical val es (h midity, press re, level, flow, speed, etc.) processed to a standard electrical signal
(0/4÷20mA, 0÷10V, 0÷60mV, 0÷850Ω) or p lse signals (freq ency, flow, co nting, etc.)
16 analog meas rement inp ts (mA, V) or 8 niversal inp ts (thermoresistance, thermoco ple and analog) or
8 p lse inp ts or 8 mixed inp ts (4 niversal and 4 p lse), not galvanically ins lated
p lse inp ts sed for flow meas rement, freq ency or p lses co nter (totalizer ) with reset inp t, can be sed
also as a bistable (digital) inp ts
4 alarm/reg lation o tp ts with so nd and vis al operating stat s signaling and e-mail notifications,
programmable characteristics, and the possibility to assign any meas rement channels that trip the alarm
saving data in standard text files stored in the recorder's internal memory (4 GB) or in a USB memory in the
FAT system with possible edition in spreadsheets in s ch software as Microsoft Excel and OpenOffice Calc
rich standard eq ipment with serial interfaces: USB (cooperation with a comp ter and USB memories), RS485
and Ethernet (100base-T, TCP/IP protocols), MODBUS-RTU and MODBUS-TCP
a web server for cooperation with any web browser (Opera, IE, Firefox, etc.), the site contains information on
active meas rement channels, time, stat s of o tp ts, recording, etc., with the possibility to present charts
sing the Google Chart API service (permanent Internet access is req ired to present charts)
the DDNS service, which enables easy access over the Internet a recorder connected to a network that has no
fixed p blic IP address, thro gh a friendly Internet address defined by the ser; the service is available only for
registered sers of pop lar DDNS services, s ch as DynDNS (www.dyndns.org), No-IP (www.no-ip.com), and
DNS-O-Matic (www.dnsomatic.com)
possibility to transfer archive data and config ration data onto a USB memory sing a USB port of the
comp ter or over the Ethernet
a color graphic display, LCD TFT, 320x240 points (QVGA) with a to ch screen, brightness adj stment, and
programmable backgro nd color for individ al meas rement channels
int itive se, q ick config ration, and clear signaling of device operating stat ses and men position
a programmable lang age of the men and the site saved on web server (Polish, English)
graphic and text methods of presentation of the meas red val es (n merical val es, bar graph, co nter, charts)
gro ping of meas rement channels to be displayed, with a tomatic formatting of the screen
programmable F b tton for q ick selection of one of the available f nctions: stop/start of recording, copying
or transfer of archives into USB memory, blocking of o tp ts, so nd alarms or to ch screen and keypad,
device and internet services stat s
a broad selection of methods of initiation of recording (contin o s, limited by date and time, repeated daily,
over or nder a permission threshold connected with any meas rement channel)
internal real time clock with a battery back p power s pply ( p to 8 years of contin o s operation)
an integrated 24 V DC power s pply s pplying the field transd cers;
compensation of line resistance for resistance sensors (a tomatic or permanent)
compensation of thermoco ple cold tip temperat re (a tomatic or permanent)
enclosed free software enabling graphic or text presentation of recorded res lt (ARSOFT-LOG-WZ3) and
config ration of parameters (ARSOFT-CFG-WZ1)
programmable types of inp ts, ranges of indications, alphan meric description of channels and meas rement
gro ps, options of recording, alarms, display, comm nication, access, and other config ration parameters
access to config ration parameters protected with a ser password or not protected with a password
parameter config ration methods:
−from the film keypad and a to ch screen located on the front panel of the device
−via the USB, the RS485, or the Ethernet and the ARSOFT-CFG free software (Windows 2000/XP/Vista/7/8/10)
or a ser's application, the MODBUS-RTU and MODBUS-TCP comm nication protocols
−from config ration files saved in the USB memory or on a comp ter disk
available protection of meas rement data from na thorized modification (check s m)
