AD-MK 350 GVD
Description
The limit switch AD-MK 350 GVD serves the switching of limiting values on analogue signals, transmitter signals and resistance thermometer. If a 2-wire transmitter is connected, it will be supplied directly through a galvanic separated and current limited supply voltage. The device has analogue inputs for current, voltage and resistance thermometer, which can be utilised alternatively. The AD-MK 350 GVD can switch maximally two independent limiting values with its two potential-free change-over contacts. The switching thresholds and operating modes can be freely parameterized. This can be carried out via the optional control panel AD-VarioControl or via the programming software AD-Studio. The status of the relevant relay is indicated via LED at the front or at the operating module AD-VarioControl.
Application
Switching limit values to active analog signals, 2- / 3-wire transmitters, and resistance thermometers, e.g. Flows, heights or temperatures.
