AD-MV 55 GX

Description

The digital temperature measuring converter of series AD-MV55 GX are freely programmable digital measuring transducer with RS485 interface. Device addresses from 1 to 99 can be set via the laterally accessible address switches. The input of all characteristics directly on the device, or use the configuration software "AD-Studio". The device fulfils all tasks of a universal measuring value recording through integral function modules such as selectable relay functions, simulation modus, free linearizing curves and a wide range of supply voltage. The operating voltage is indicated by a green LED. The data communication is signaled by a yellow LED. Invalid measurement signals outside the defined measuring range are detected. In this case, the green LED flashes. The power supply as well as the RS485 bus interface is possible via the rear DIN rail connector.
