AS-Interface analog module VBA-4E-G4-Pt100

The VBA-4E-G4-Pt100 analogue module has four analogue inputs for Pt100 RTDs. The asynchronous transformation of measured values and the data transfer is accomplished in accordance with AS-Interface profile 7.3. The resolution of the analogue values is 16 bit or 0.1 °C. System disturbances are eliminated using a programmable filter (50 Hz/60 Hz).

The IP65 rated G4 module is especially suitable for use in hazardous environments. Connection to the measured-value transmitters is established by means of cable glands and cage tension spring terminals thus making the installation especially user-friendly. For preaddressing the module, it can be plugged directly onto the adapter of the hand-held programming device VBP-HH1.

Various bases are available for the module. Use the U-G1F base to connect to the ASInterface flat cable, and the U-G1P base to connect to the round cable. The bases can, at the same time, be used as IP67 rated distributor box. Moreover, they both have two connection possibilities for AS-Interface cables.

Output modules often have to be mounted in series with input modules. The outputs of the output modules are supplied externally with power. If the power is supplied via a flat cable, the power cable has to be mounted in the base of the input module. The U-G1FF base should be used in this case. The VBA-4E-G4-Pt100 then uses the AS-Interface cable instead of the power cable.
