Analog Value Limiter
The snap-on-module VM290 includes two functions:
Analog value limiter
On 0-point und amplification adjustable amplifier, whose output voltage can be limited between 0 und 10V. The limit is separate adjustable for + und - by two helical potentiometer in the front of housing. For controlling of adjustment, at terminals 7 and 8 the values of limiting can be measured.
1:1 amplifier for 0...10V signals, which inverts its output by a control signal of 24Vdc at terminals 4 and 5.
The device has a galvanic separated wide-range power supply, that allows a connection at all usual ac/dc supply voltages (19Vdc...255Vac). Easy to mount, the module simply requires snapping onto TS35 mounting rails.
