Products overview:

ZW - LED seriesSurface encapsulation modular process, greatly improve the anti-interference ability of the instrument, display, control, transmitting, communication, universal signal input, and other functions, suitable for temperature, humidity, pressure, liquid level, the instantaneous flow capacity, speed and other physical quantities detection signal display and control, and can be in various nonlinear input signal for high precision linear correction.Can be widely used in electric power, metallurgy, chemical, petrochemical, paper printing and dyeing, brewing, tobacco, space base, and other fields.

ZW series - LED large screen digital display, no jumper wire technology, make the input ports have universal signal input function, simply by changing the internal parameters, can achieve a variety of input signal (various thermocouple, heat resistance, far eastone pressure, mV, standard voltage/current signal) easy to switch between.Circuit board after optimization design, and constantly improve production technology, reduce the temperature drift and improve the anti-jamming performance to ensure product stability and reliability of the stability in the long-term work.With high brightness LED digital display and high resolution column display (display), make the measurement/control values show more clear and intuitive.

ZW series - LED large screen digital display the output of the loop adopts photoelectric isolation, strong anti-jamming capability.But with serial communication interface, but with all sorts of two-way communication equipment with serial interface, network control system.Have a variety of standard appearance size, can apply various measurement control occasions.The whole machine adopts card into the type structure, the installation is very simple.

Second, the scope of application:

ZW series - LED large screen digital display in the boiler room, bath, spa, square, Banks, government agencies, etc.

Three, the basic performance:

1, 4-20 ma, 0 to 10 v, mV, pulse signal, thermal resistance, thermocouple, such as signal input, in addition to the display functions, also optional transmitting, alarm, communication function.

2, according to temperature, temperature and humidity, pressure, flow, speed, weight, liquid level, counting...Such as industrial parameter values.

3, display USES high brightness red leds, the size of leds including 1.8 ", 2 "3", 4 ", 5 ", 8 "and 10" (inches)

4, aluminum profile is used for the shell, not completely sealed, can only be used indoor.

5, connection for aviation plug

6, channel, logo, quantity unit identification, using the paste way.

7, optional respectfully built-in clock, the error is less than 2 minutes, year, month, day, hours, minutes, seconds, week display, etc.

8, the dimensions and the channel number and LED quantity, size, function, quantity unit identification requirements, etc.And is subject to the restrictions of transportation, packing conditions, selection should consult with.

Four, the main features:

1, universal input function

2, automatic calibration and manual calibration function

3, multiple protection, isolation design, strong anti-interference ability, high reliability

4, good software platform, and have the ability to develop secondary and to meet the special function

5, advanced modular structure, with the powerful instrument chip, function combination, the system upgrade is very convenient

Five, the technical parameters:

Alarm output: instrument with multiple output relay, relay contact capacity AC220V / 5 a or AC220V / 1 a.Zui can bring more 16 relay, can choose the upper limit and lower limit control, the control value and return difference values within the range set freely;

Analog output: 4 ~ 20 ma, 0 ~ 10/20 ma (load resistance Ω 250 or less, the load is too large to be marked).1 ~ 5 v, 0 ~ 5 v, 0 ~ 10 v (load resistance 200 k Ω or higher);

Adopting the D/A chip, the 12 digits output;

Communication output: isolate the communication interface RS485 / RS232 baud rate from 1200 to 9600 BPS;

Feed output: 30 ma, DC12V DC24V / / 30 ma.

Automatic temperature compensation: 0 ~ 50 cold end temperature compensation, error: + / - 1 ℃;

Electricity source, switching power supply of 85 ~ 265 vac or DC24V or DC12V;

Power consumption: 4 w;

Ambient temperature (20 ~ 70 ℃ (room temperature boot operation after 30 minutes, can be gradually under extreme temperature);

(0 ~ 50 ℃ (thermocouple signal input)

Relative humidity: 85% or less without any condensation to avoid with corrosive and flammable and explosive gases in use;

Panel size: 3400 mm long, 2200 mm wide, deep 60 mm, and does not contain pendant.

(the company instrument research and development production, variety, full functions, such as the user can choose fast sampling, can be 200 times per second, 18 high precision A/D acquisition, high precision 16 bit D/A output, the input signal of 20 curve correction, five full display or six, liquid crystal display, special input signal, multiple relay alarm buzzer output, high power supply output, etc., when placing order, indicate).
