AS-Interface sensor/actuator module VAA-4E4A-G4-ZE/E2

The AS-Interface Module VAA-4E4A-G4-ZE/E2 has 4 inputs and 4 outputs. Both 2-wire and 3-wire sensors and also mechanical contacts can be connected to the inputs. The sensors are supplied from the module. The outputs are electronic, which can be loaded to a max. 24 V DC and 1 A per output.

The G4 Module is particularly suitable for harsh field conditions. The connections to the sensors/actuators are made via cable glands and cage spring terminals. This makes the installation particularly user-friendly. Pre-addressing can be carried out by plugging the module directly into the VBP-HH1 hand-held programming device adapter.

An LED is provided for each channel on the top of the module to indicate the current switching status. Communication monitoring is integrated in the module. In the event of faults on the bus the monitoring system switches off the current to the outputs.

Connection the AS-Interface transfer cable and the external 24 V DC supply can be achieved by means of flat or round cable. If the AS-Interface flat cable is used, the U-G1FF base component is required. The contact with the two cables is made via the AS-Interfacestandardised EEMS interface, i. e. by means of the insulation penetration technique.

If a round cable is used, the U-G1PP base component is required. This base also provides the option of connecting both the AS-Interface cable and the external power supply.

Note:

The device features communication monitoring. When this is active, it switches off the power to the outputs when no communication has occurred on the AS-Interface cable for more than 40 ms.

In the event of overloading of the internal input power supply or output supply, a signal is communicated to the AS-Interface master via the "Peripheral error" function. Communication via the AS-Interface remains uninterrupted.
