SETTING UP YOUR SYSTEM
DRN Computer Connection

INPUT TYPE
Min. Low level signal input (magnetic pickups): From 0 mV to 120 mV

Open Collector NPN (Use software to set: 3 Kohm pull up to 5V): Max. current source = 1.66 mA

Open Collector PNP (Use software to set: 1Kohm pull down to RTN): Max. current sink = 12.5 mA

TTL/CMOS Input: (Use software to set: no pull up/down).
Low <= 0.8 V , High >= 3.5 V (For Input: 0.2 Hz to 16 KHz)
Low <= 0.8 V , High >= 12 V ( For Input: 0.2 Hz to 50 KHz )

NAMUR Sensors (Use software to set: 1Kohm pull down to RTN and 8.2V Excitation.)

For measuring a low level signal riding on top of a large DC signal, connect a 0.1 uF capacitor. See Detail. Use software to set 1Kohm pull down to RTN.

OPERATING MODES
FREQUENCY RANGE: Range = 0.2 Hz to 50 KHz

Totalize with Reset: Range = 0 to 999999, if reading is larger than 999999, then reading is converted to floating point number, i.e. 9.99E9 (maximum).

A-B Totalize (Reset input used as +A input): Range = -99999 to 999999, if reading is larger than 999999, then reading is converted to floating point number, i.e. -9.99E9 (minimum), 9.99E9 (maximum).

Quadrature (Reset input used as second input): Range = -99999 to 999999, if reading is larger than 999999, then reading is converted to floating point number, i.e. -9.99E9 (minimum), 9.99E9 (maximum).

ISOLATION
Three way isolation up to 1800 V Peak for 1 minute, 354 V Peak continuous per IEC spacing.

Normal mode rejection 60dB

Common mode rejection 100dB

INPUT OVER-CURRENT PROTECTION

10% Above full scale continuously

100% Above full scale for 10 seconds

INPUT IMPEDANCE
Input: 1Mohm to +EXC
Reset: 100K to +5V

INPUT OVER-VOLTAGE PROTECTION
With 1K pull down: 14V
With 3K pull up: 20V
Without pull up/down: 60V

EXCITATION
5, 8.2 or 12.5V at 25mA, programmable

ACCURACY AT 25 ░C
▒ 0.1% of FS Crystal time base accuracy: ▒ 50 ppm

TEMPERATURE STABILITY

▒ 50 ppm/░C typical

Time base stability: ▒ 1ppm/░C

STEP RESPONSE FOR RS485 OUTPUT
0.1 second to 99% of the final value
(Filter time constant = 0, Gate time = 0.05 Sec)

RESPONSE TIME
To verify the response time, check the carriage return <CR>, it will be sent at the end of the response. You can send another command after you receive the <CR>.

i.e. send: *01X01 / response: 01X01
Note: Only for reading (X01 command). 01 is address.

Frequency mode: response time is controlled by the gate time. If gate time is increased then response time is longer.

Other modes: response time is not controlled by the gate time.

WARM UP TO RATED ACCURACY
30 minutes

INPUT POWER
10 to 32 Volt

DC POWER CONSUMPTION
3 Watts (125 mA at 24 V DC)

OPERATING AMBIENT
-5 to +55 ░C

STORAGE TEMPERATURE
-40 to +85 ░C

RELATIVE HUMIDITY
90% at 40 ░C non-condensing
