The PRC 96x24 and PRC 96x48 limit value switches with profile scale are suitable for monitoring voltages, currents and, in conjunction with transducers, also for frequency, power or power factor.
Limit signals are formed via electronic comparator circuits and are therefore insensitive to vibration.
The units can be optionally equipped with a transistor or relay output with one (min, max) or two (min/max) change-over contacts. The relay output works either according to the closed-circuit current or open-circuit current principle. Measuring input and outputs are galvanically isolated (transistor output only with auxiliary voltage AC).
Limit values and the zero point can be set from the front.
