Alarm output: normally open relay contact output, where the contact capacity is1 A/250 VAC (resistive load)
(! Note: Please do not carry load directly in case the load exceeds the contact capacity of relay.)
Feed output: DC24 V ± 1, load current ≤ 250 mA
Communication output: RS485/RS232 communication interface, 1,200 ~ 57,600 bps baud rate (able to be set); standard MODBUS RTU communication protocol is adopted; the communication distance of RS-485 can be as long as 1 kilometer; the communication distance of RS-232 can be as long as15 m; EtherNet communication interface is adopted, where the communication speed is10 M.
Comprehensive parameters
Measurement accuracy 0.2%FS±1d
Sampling period 1 s
Setting mode Setting via soft touch panel button; setting values of parameters are locked with passwords and will be saved permanently in case of outage.
Display method 7-inch 800 * 480 dot-matrix widescreen TFT high brightness LCD display supporting color graphics display;
LED backlight; with clear pictures and wide visual angle.
The data logger supports display of characters, figures, conditional curves, bar graphs, etc.; through panel button, page turning, forward and backward search of historical data, time scale change of curves, etc. can be realized.
Data backup Data backup and conversion storage of USB flash disk and SD card are support, where the maximum capacity is 8 GB; FAT and FAT32 formats are supported.
Storage capacity The capacity of the internal Flash memory is64 MByte .
Recording interval Nine options including 1, 2, 4, 6, 15, 30, 60, 120 and 140 s can be selected.
Storage length (continuous record without power-off) 24 days (1 s interval) - 5825 days (240 s interval) Calculation formula: recorded time (day)
(! Note: For calculation of channel number, the program divides the channel number into five options, namely 4, 8, 16, 32 and 64, and the bigger figure should be regarded as the channel number for calculation in case the channel number of the instrument is between the said two options. For example: If the channel number of the instrument is 12, then 16 should be adopted in the formula.)
Environment condition Environment temperature: -10 ~50°C;
Relative humidity: 10 ~ 90% RH (without condensation of moisture);
Avoidance of contact of high corrosive gas.
(! Note: If the field environment is poor, special instruction should be given when ordering.)
Working power supply AC 85 ~ 264 V (power supply of the switches), 50/60 Hz;
DC12 ~ 36 V (power supply of the switches);
Power consumption ≤20 W.
