8 Paperless Recorder

8 Paperless Recorder

1 Input

3 analog input channels support various types of signal. The following options can be

Selected to input through meter configuration.

Voltage signal: 0~5V, 1~5V, 0~20mV, 0~100mV;

Current signal: 0~20mA, 4~20mA;

Thermal resistance: Pt100, Cu50;

Thermocouple: B, E, J, K, S, T.

2 Output

1 isolated 24VDC feedback output can supply a current as much as 75mA.

3 Accuracy

Real-time display: ± 0.2% F. S.;

Recall accuracy: ± 0.2% F. S.;

Clock accuracy: ± 2S/Day

4 Record Interval

8 measuring ranges from 1 second to 240 seconds: 1/2/5/20/40/60/120/240 S.

5 Record Capacity

4MBit. The user can allocate it to three input channels through instrument configuration

(0.5MBit per unit).

6 Record Time

If the power is ON, the total record time T of every channel can be calculated by

The Record Interval t and Record Capacity n. See the formula as follows:

T=0.74× N× T;

Where: T: Day;

T: S;

N: M, it's value can be 0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5 or 4.0 (optional).

For example: In case n=4.0, t=240S, this channel can record for T=710.4 days.

7 Alarm Output

2 passive Contact Outputs. Contact Capacity: 1A 30VDC.

8 Communication

RS485 mode: Complying with open MODBUS RTU slave protocol, and the baud rate can be

Set to 1200 bps, 4800 bps, 9600 bps, 19200 bps, 38400 bps or 57600 bps.
