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 as 15 m; EtherNet
communication interface is adopted, where the communication speed is 10 M. |

Comprehensive
parameters
Measurement accuracy |
0.2% FS±1d |
Sampling period |
1s |
Setting mode |
The button is set in the form of panel soft touch; 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 color
graphics and LCD display; LED backlight; with clear pictures and wide visual angle. Display contents can be composed 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; FATand FAT32 formats are supported. |
Storage capacity |
The capacity of the internal Flash memory is 64 M Byte. |
Recording interval |
Nine options including 1, 2, 4, 6, 15, 30, 60, 120 and 140s 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 |
≤20W. |
