DL000ID Advanced Sensor Protection Circuits ASPC Developed to protect the current transducer from typical fault conditions: Unit is un-powered and secondary circuit is open or closed Unit is powered and secondary circuit is open or interrupted Both DC and AC primary current up to 00% of nominal value can be applied to the current transducers in the above situations without damage to the electronics. Please notice that the sensor core can be magnetized in all above cases, leading to a small change in output offset current (less than 0ppm) Status pins When transducer is operating in normal condition, the status pins (3 and 8) are shorted. Status pins properties: - forward direction pin 8 to pin 3, maximum forward current 0mA - maximum forward voltage 60V, maximum reverse voltage 5V Accessories 4-channel power supplies unit for connection up to 4xDL000 : DSSIU-4 6-channel power supplies unit for connection up to 6xDL000 : DSSIU-6 Transducer cables in 5 lengths (m - 5m - 0m - 5m - 0m): DSUB - DSUB5 - DSUB0 - DSUB5 - DSUB0 Transducer cable 3m for connection to end-user s power supply: Transducer cable for lab PS (with access to current output via 4 banana jacks) Please visit Danisense homepage for relevant datasheets page 5-07--9
