Product Description

ZDR-Wn universal recorder and transmitter to connect various types of sensors can be used as the temperature logger, humidity logger, temperature and humidity recorder, the current recorder, voltage recorders, frequency recorder, speed recorder, flow recorder, level recorder, recorder, etc. to use power.
    Is small, low power consumption, high precision, versatile, stable, reliable and so on.
    Universal input module so that users do not replace any device can achieve thermal resistance, thermocouple, standard signal such as a full range of input. With no paper record, alarm, power distribution, transmitter output, PID control and other functions.

1, input
Supports two analog input channels.
Supports multiple signal types, simply by the configuration software can select the following signal input:
Voltage signal: 0 ~ 20mV, 0 ~ 100mV, 0 ~ 5V, 1 ~ 5V
Current signal: 0 ~ 20mA, 4 ~ 20mA
Thermal resistance: Pt100, Cu50
Thermocouple: B, E, J, K, S, T 5-inch LCD screen;

2, output
To support an analog signal (4 ~ 20mA) output channel, transmitter output or PID control output. Load capacity of 750Ω (maximum).
3, accuracy
Real-time display: ± 0.2% F.S.;
Curve shows: ± 0.2% F.S;
Recall precision: ± 0.2% F.S.;
Note: The thermocouple cold junction error should be removed

4, recording interval
From 0 to 240 seconds, is divided into 9 files: 0/1/2/5/20/40/60/120/240 S, in which 0 seconds that are not recorded.

5, recording capacity
4M Bit (FLASH capacity)

6, recording time
In the case of non-power-down, according to records of the different intervals and record points, instrument can record the maximum time by the following formula:
The longest record of the number of days = 0.74 × configuration storage capacity (M) × recording interval (S)

7, alarm output
Supports two passive contact output, contact capacity 1A 250VAC / 1A 30VDC

8, communication
Support RS485 communication mode, using MODBUS RTU open from protocol, the baud rate to support the following options: 1200 bps, 4800 bps, 9600 bps, 19200 bps, 38400 bps, 57600 bps.

Nine, the screen
Display resolution: 192 * 64, refresh rate: 1Hz

Payment Terms︰ Bank wire transfer
