Optimized for DC railway and light rail transit applications, P40000 ProLine Signal Isolators provide >0.1% gain error, cutoff frequency of >5 kHz with optional loss pass filtering, and >0.1 ms rise times. Units also offer high immunity to transient noise of T-CMRR >115 dB, with virtually no influence from common mode voltages. For shunt based current measurements, P41000 Series can accept voltages from ±60 mV to ±100 V, converting them into impressed ±20 mA, ±10 V, or 4-20 mA output signals.
