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 rails in accordance with EN 50 022. When using passive isolators, ensure that the current-driving voltage of the measuring transducer UB is sufficient for driving the maximum current of 20 mA over the passive isolator with the power loss of UV = 2.5 V and the load RB. This means: The graphic shows the input voltage of UE dependant on the load RB considering the power loss UV. If you know your load, the lowest voltage, which the sensor should use to drive a maximum current of 20 mA via passive isolators and loads, can be read from the Y-axis. Input voltage depending on the load at IA = 20 mA UB ≥ UE = 2.5 V + 20 mA * RB UE /V 25 UB UV = 2.5 V I UE I 20 I I MCR-1CLP RB 15 10 5 UV = 2,5 V 0 200 400 600 800 1000 RB /Ω Headquarters: © Phoenix Contact GmbH & Co.
