Channel configuration Each channel does have 5 connectors. • Transducer (DSUB9) for connection to the transducer • YELLOW Calibration + (4mm Banana) the positive connection for the calibration current • YELLOW Calibration - (4mm Banana) the negative connection for the calibration current • RED + (4mm Banana) is positive output from the measured current • BLACK - (4mm Banana) is negative output from the measured current Current output configuration DSSIU-6-1U will send the measured current to the RED and BLACK 4mm banana jacks. RED being connected to pin 6 on the transducer. BLACK...

DSSIU-6-1U Calibration winding access Each channel gives access to the calibration winding of transducers with this feature. Currently the following transducers do support this functionality.  DS200IDSA-C1000 - 1000 turns calibration winding (Max 200mA) - Equals a primary current of 200A  DS200IDSA-C100 - 100 turns calibration winding (Max 100mA) - Equals a primary current of 10A  DS600IDSA-C100 - 100 turns calibration winding (Max 100mA) - Equals a primary current of 10A  DS2000IDLA-C100 - 100 turns calibration winding (Max 100mA) - Equals a primary current of 10A Each transducers...

Status port The status port provides access to the status of the system via optical isolated pins in a DSUB15. Overview: (Current direction is from + to -) Use a pull up resistor value which does not exceed 100mA when the pin is @ 1V. Example: 5V supply, resistor of 1kOhm is connected between 5V and + of channel 1 (pin 1) and pin 9 is connected to 0V. If the transducer is working correctly pin 1 and 9 are shorted with below optocoupler circuit. The voltage on pin 1 will be around 1V and current I®=(5V-1V)/1kOhm=4mA Precision - Innovation www.danisense.com

DSSIU-6-1U User Guide Intended use: The DSSIU-6-1U is intended to be used for powering up to six Danisense current sensors. The sensors which can be powered are all 200A, 600A, 900A and 2000A transducers. Instruction for use: 1. Do not power up the device before all cables are connected 2. If the DSSIU-6-1U is intended for desk use, mount the rubber feet which are part of the package. If the DSSIU-6-1U is intended for Rack mounting, use the screw kit for mounting and do not mount the rubber feet. 1. Connect a DSUB cable between DSSIU-6-1U and each sensor 2. Connect a low impedance...
