INTRODUCTION

The RDA Paperless Recorder integrates measurement, display, alarm, data logging into one slim
instrument. It provides multi-channel recording with a touch screen display as well as alarm
generating capability. Depending on the model, the RDA Paperless Recorder provides 2, 4, or
6 inputs. There are two different size panels, 5-inch, 7-inch. The RDA-740 and RDA-760 models
are only 40mm thick which allows it to be installed in machinery or equipment where space is
limited. The main parameters are set in one single interface through the industrial grade touch
screen.

1. All-in-one
Input, display, monitoring, recording and

output are all integrated in one paperless
recorder. There is no external HMI required
and the Recorder is simple and easy to install.

2. Touch Screen Interface
All the configuration and operation is done

on the industrial graded touch screen without
any hardware PIN setting.

3. Durable Components
Low power consumption. 12 months warranty

on quality. HMI graphics and datalogging are
processed by one ARM processor in dual CPU
mode. EMC testings complied (±4KV/5KHz
according to IEC61000-4-4 (Electrical Fast
Transient); 4KVaccording to IEC61000-4-5
(Electrical Surge).

4. Outstanding anti-interence

Ultra performance hardware greatly reduce
the temperature drift and the interference
among the input channels. The measurement
accuracy of multi-channel reaches that of
single channel.

5. Abundant Recording Function

Real-time trend graph, bar graph and history
trend graph are provided. Measured data
and alarm record can be shown on screen as
a report table. Storage size is 150MB. Data
stored can be viewed as graph or table and
exported to external USB storage deivce.

The RDA Paperless Recorder does not have a sealed housing. The device
should not be exposed to excessive dust, moisture, or shock during
installation. Only professionally trained personnel should operate and
maintain this device.

RDA-TC: Qualified compensation wires of thermocouple should be directly connected to the back
of the instrument. Do not connect the incorrect polarity of compensation wires. Cold junction
compensation error will occur if the above requirements are not met. Cu50 copper resistor can be
connected terminal JC and negative of thermocouple (RDA-520: terminal 17 and 20; RDA­740/RDA-760: terminal 1 and 4) as thermocouple cold junction compensation temperature. Short­connection will have ice-point compensation.

RTD connection can be applied either two-wire or three-wire method by setting the “B” digit in
“AF” parameter. Two-wire method saves quantity of wire connections and allows more number
of input channels. However resistance of lead wire is required to be measured to eliminate error.
Three-wire method is the traditional wiring method. If the resistance of each lead wire is equal,
the resistance value is not required to be measured. However the number of channels possible is
half of that of two-wire method. The instrument applies a number of policies to leverage the error

brought by the lead wire resistance. In applications requiring higher accuracy, three-wire method
is recommended. The resistance of each lead wire should be less than 2Ω.

Lead wire resistance in two-wire method can be saved to parameter “Sc” to compensate during
measurement. However, the lead wire resistance (copper or aluminum material) changes with
temperature. The instrument can compensate the change of lead wire resistance according to
room temperature sensor. However this kind of compensation is not suitable in the application
that the change of lead wire resistance does not synchronize the change of instrument
temperature. Three-wire method is recommended in this situation.

Digital Input

High Limit

(dIH x)

dIH/dIL define the corresponding scale of linear inputs such as mV, 0~5V, 1~5V,
0~10mA, 4~20mA, interpreting the measured physical unit. The range of signal shown is

-1999 ~ +9999 with decimal place defined by parameter dIP. When the temperature input
is retransmitted, dIH/dIL also define the high/low limit of temperature.
For example, a pressure transmitter transmits the pressure to a standard 1~5V signal to
input channel 1. The input at 1V indicates the pressure=0MPa and 5V indicates the
pressure=1MPa. The expected display resolution is 0.001MPa. The parameters
recommended are Sn1=33, dIP1=3, dIL1=0.000, dIH1=1.000

Input Shift
Correction

(Sc x)

Sc provides shift correction to the internal error of sensor or input signal or the error of
cold junction compensation in the instrument. When 2-wire RTD is used, Sc corrects the
error due to lead wires of RTD.
For thermocouple or three-wire RTD inputs, the units of Sc is 0.1℃. For example, when
Sc=-100, the measured temperature will be 10℃ lower.
For two-wire RTD inputs, the magnitude of correction = (Sc* signal unit). The signal unit
of Pt100 or 0~400ohm input is 0.02Ω while that of Cu50 or 0~240 Ω input is 0.012 Ω. For
example, when Sc=-50, input type is Pt100, the correction will be -50 * 0.02 Ω=-1 Ω. If the
lead wire resistance is 1 Ω, this cancels out the lead wire resistance.

(2) Thermocouple or RTD inputs: dIP sets the display resolution of

0.1℃.

Note: dIP is only effective in display. The internal temperature resolution is fixed as

Function

(AF)

The formula of AF value is:
AF=B*2 + D*8 + E*16 + H*128

B=0, RTD input use two-wire wiring;
B=1, RTD input use three-wire wiring (suitable module required);
D=0, Normal;
D=1, Low limit alarms of all channels are changed to high limit alarms.
E=0, Normal;
E=1, Set M2(MIO) and M3(OUPT) supporting single channel input only.
H=0, Normal;
H=1, For thermocouple or RTD input, the measured value PV=PV*dIH / 2000.0. Addition
in input specification can be further applied.

Example setting
To make use of all alarms to high limit alarms,
D=1, then AF = 1*8 = 8.

Digital Filter

(dL x)

The value of dF will determine the ability of noise filtering.
0: no filtering;
1: filtering with mean;
2~40: filtering with mean and integral.
When a large value is set, the measurement input is stabilized but the response speed is
slow. Under environment with great interference, increasing dF gradually will adjust the
momentary fluctuation of measured value falling between 2 to 5 unit.
When the instrument is being metrological verified, dF can be set to 0 or 1 to increase the
response speed.

NO/NC Switch

(nonc)

Single channel relay module provides both normal open and normal close output. Dual

nonc=0, L3 dual dual relay installed in MIO, OP1, OP2 AL1, AL2, AU1 and AU2 is
normal open, NO.
nonc=127, all module used as alarm turns to normal close, NC.
Formula of nonc is as below:
nonc = A*1 + B*2 + C*4 + D*8 + E*16 + F*32 + G*64
A,B,C,D,E,F,G respectively set NO/NC output of OP1, OP2, AL1, AL2, AU1, AU2 and
MIO. 0 means the corresponding output is NO, and 1 means NC output.
