2. INTEGRATED BODY TRANSDUCERS (DS, DL & DQ series)
2.1 Introduction and overview
The DS, DL & DQ series, ultra-stable and high precision current transducers are based on closed
loop flux gate principle allowing to achieve ppm level accuracy, excellent linearity and stability versus time.
The integration of the sensing head and the control electronics in a single housing allows a compact de-
sign. The following table shows the rated current range overview and model names.

2.3.2 Electrical connection instructions
This chapter describes the electrical connection of the transducer according to their types of output
(current or voltage).
2.3.2.1 Current output
Current output models are identified by the letter I in their model names (e.g. DS200ID).
2.3.2.1.1 Standard version
Electrical connection is ensured by a standard 9-pin DSUB connector (DSUB9). Jackscrew socket
tapped hole UNC 4-40 inches (“D-SUB JACKSKT-SCREW, UNC 4-40, UNC 4-40” inches ).
The pin assignement is shown below.
* open collector for status signal: when the transducer is operating in normal condition, status pins are shorted. Sta-
tus pins are open in case the « zero flux » state is not maintained (transducer is saturated or faulty).
Status pin properties:
- Forward direction pin 8 to pin 3
- Maximum forward current 10mA
- Maximum forward voltage 630V
- Maximum reverse voltage 5V
*
It’s necessary to connect the output pins to an External Measurement Resistor to enable the current
feedback loop (zero flux) for a correct operation of the device. Please refer to chapter 4.4 on External
Measurement Resistor for more details.

2.3 Installation & Operation
2.3.1 Mounting instructions
2.3.1.1 Positive current flow: Each transducer is marked with an embossed arrow at the
back of the housing for the positive current direction, as shown below. Please respect the current flow indi-
cation to ensure that the output signal is in phase with the input signal.
2.3.1.2 Fastening torques: The devices is suitable for different fixation configurations,
using the mounting plates designed for that purpose.
Please respect the fastening torques indicated below to avoid damaging the device.

2.3.2.1.2 Version with calibration winding
For some applications, it’s preferable to perform a prior functional / accuracy check of the device at
full scale or a fraction of full scale before apllying the power. For that purpose, a primary winding, most
commonly of 100 turns or 1000 turns is added. The terminals of this winding are available at pin 2 and 7 of
the DSUB9 connector (e.g. DS200ID-CD1000) as shown below
*
*
2.3.2.2 Voltage output
Voltage output models (10V or 1V at rated current) are identified by the letter U in their model
names (e.g. DS200UB-10V). The transducer’s output signal is accessible via the BNC connector to en-
hance immunity to induced noises as shown below .
It’s also possible to have the terminal of the calibration winding on a separate BNC connector (e.g.
DS200ID-CB1000). For this version, the electrical connection is similar to the volage output model in the
following section.
Thin wire are used for the test winding due to space restriction. Please observe the current limit for
the test winding, specified in the relevant datasheet to avoid damage to the wire.

2.3.3 Power supplies interface units
2.3.3.1 Main features
The current transducers are designed for operation with a ± 15V DC power supplies with the follo-
wing requirements:
• Tolerance max: ±15VDC ±5%
• Max. ripples: 15 mVrms
• Mini. Current requirement *: I consumption (Ips or Ins) + secondary current Is @
max. primary current (see below example)
* e.g. DS600ID measuring up to ± 900A.
- I consumption (see datasheet) Positive current consumption Ips: 104mA
Negative current consumption Ins: 96mA
- Secondary current Is (ratio: 1:1500) Is = ± 900A x (1:500) = ± 600mA
The minimum current that the power supply needs to provide is:
For +15VDC, I output = Ips + Is = 104 + 600 = 704mA
For –15VDC, I output = Ins + Is = 96 + 600 = 696mA
2.3.3.2 Multi-channels power supplies interface DSSIU series
Danisense recommends the 1U rack-mount multi-channels power supplies interface DSSIU series
for best performances, many useful features and options. The following table shows the different options:
Features DSSIU-4, DSSIU-6
- Output voltage: ± 15V ± 5% (per channel)
- Input voltage: AC 100V to 240V, 47Hz to 63Hz

2.3.3.3 Connection of calibration winding with DSSIU-6-1U (or DSSIU-6-1U-V)
When a device with calibration winding type - CD[n turns] is connected to the DSSIU-6-1U using the
optional DSUB cable, the terminals of the calibration winding are accessible via the yellow banana sockets
at the back panel of the DSSIU-6-1U (or DSSIU-6-1U-V). It’s very convenient to carry out a simultaneous
calibration of 6 devices connected in serial (illustration below).

2.3.3.4 Voltage Output Modules (VOM)
A voltage output module (VOM) is a PCBA containing a low drift, precision measurement resistor
(RM) and a signal conditioning circuit which allow conversion of the device’s rated nominal current output
to a 1V or 10V voltage signal. Up to 6 VOMs can be factory mounted into the 6-channel power supplies
interface unit (DSSIU-6-1U-V).
