| Item Description | Isol.amplifier PS 19-255VAC/DC in switchable out switchable / potential isolation amplifier • 3WAY-SEPARATION • unipolar • calibrated switchable inputs and outputs • linearity error <0.2% • wide-range power supply 19VDC...255VAC the isolating amplifier VM380 is used to provide galvanic isolation of standard signals. The input and output signals CAN be selected using the dip-switches on the front of the housing. The calibrated switchover takes place within the documented tolerances. The input signal is converted into an optical signal before being converted back to voltage and current signal in the output stage. Zero point and slope CAN be adjusted using the trimmers in order to do on-site adjustments. The optional sensor supply (VM380S) CAN be used to power a two-wire measuring transducer |
