Multi-Channel Passive Isolator MCR-...CLP-I/I-00 • Electrical isolation without additional power supply • Current signals 0(4)...20 mA • 1-, 2- and 4-channel versions I I 1. Description MCR-1,2,4CLP-I/I-00 passive isolators are used for the electrical isolation and processing of analog 0(4)… 20 mA standard current signals. The blocks provide electrical isolation between the control electronics and process I/O. In addition, interference signals above 75 Hz are effectively suppressed. Input and output circuit do not require separate auxiliary power. The modules obtain this power from the input signal. The modules are snapped onto symmetrical DIN The graphic shows the input voltage of U rails in accordance with EN 50 022. E dependant on the load R considering the power loss When using passive isolators, ensure that the B U . current-driving voltage of the measuring transducer U V B If you know your load, the lowest voltage, which the is sufficient for driving the maximum current of 20 mA sensor should use to drive a maximum current of 20 over the passive isolator with the power loss of mA via passive isolators and loads, can be read from U = 2.5 V and the load R . V B the Y-axis.
