Example 1: A DS2000 is wrongly connected to a DS200 voltage output channel. The over current will burn a non recovering fuse inside the DSSIU-6-1U-V to protect the current to voltage module from damage. Example 2: A DS200 is wrongly connected to a DS2000 voltage output channel. The DS200 does not create an overcurrent, but the output voltage will be wrong. Precision - Innovation www.danisense.com

DSSIU-6-1U-V 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...

dani/ense 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 above 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-V User Guide Intended use: The DSSIU-6-1U-V 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-V is intended for desk use, mount the rubber feet which are part of the package. If the DSSIU4 is intended for Rack mounting, use the screw kit for mounting and do not mount the rubber feet. Connect a DSUB cable between DSSIU-6-1U-V and each sensor 3. 4. Connect a low impedance...
