| Description |
Optical Coupling
DLS100 connects to the DS8000 via a flexible cable through which it receives power and stimulus signals in a digital format. Up to eight DLS100 isolators can be connected independently to one DS8000. Very high isolation is achieved through the use of optical coupling of the digital signal and a galvanically isolated DC power supply within the DLS100. Unlike some other multi-channel isolators, this digital isolator can be located at the site of the experiment, allowing the use of short connecting leads and thereby preserving high isolation and fast signal rise and fall times.
Two modes
The DLS100 operates in two modes: current source or voltage source. In the current source mode, the output current is proportional to the amplitude and polarity of the signal generated by the DS8000. In the voltage source mode, the output voltage is proportional to the amplitude and polarity of the signal generated by the DS8000. The DLS100 has user-selectable push-button switches that select different current or voltage ranges (the full-scale current from 100 nA to 10 mA, or the 10V and 100V full-scale, respectively). Three status indicators on the DLS100 indicate power on, activity (presence of signal from DS8000) as well as an alarm (over-range condition) indicator. Over-range can occur when the resistance of the load (the experiment) is too high for the current or voltage that is demanded from the DLS100. |
