Feed Isolating Amplifier
transmitter feeding 20...30Vdc
linearity error 0.1%
wide-range power supplies 19Vdc...255Vac
The series of separation amplifiers VM240...VM247 is used to feed transmitters (e.g. for pressure, level, flow etc.) and for the potential separation and signal conversion of their analog outputs. Sensors in two-line and three-line technique can be connected (see connection examples).
The devices have a wide-range power supply, that allows a connection at all usual ac and dc supply voltages. The feeders work unipolar and have three-way separation of the potentials between input, output, and auxiliary energy.
Eight types of devices allow for electrical insulation trans-mission respectively conversion of standard signals.
