Description
Description
The DR910 passive isolator is used for the electrical isolation andprocessing of analog 0 to 20 mA or 4 to 20 mA standard current signals.The DR910 provides electrical isolation between the controlelectronics and process I/O. In addition, interference signals above75 Hz are effectively suppressed. Input and output circuit do notrequire separate auxiliary power.
The DR910 obtains power from the input signal. The modules aresnapped onto symmetrical DIN rails in accordance with EN 50 022.When using the DR910, ensure that the current-driving voltage of themeasuring transducer is sufficient for driving the maximum current of20 mA, with a power loss of 2.5 V (2.5 V + (20 mA * RLOAD). Voltage drop across the input iscalculated by determining the load resistance of the output loop,drawing a vertical line to the curve (see diagram), then horizontally tothe voltage drop.
The energy for the supply on the input side is taken from the analoginput signal. Due to the dynamic input resistance, a power loss ofapproximately 2.5 V drops at the module input.
