VBA-4E3A-KE-ZEJQ/E2L 228630 Pepperl+Fuchs Module

The AS-Interface I/O module VBA-4E4A-KE-ZEJQ/E2L is a control cabinet module with 4 inputs and 3 electronic outputs. The housing is only 22.5 mm wide and takes up little space in the control cabinet. The module is mounted by snapping onto the 35-mm DIN rail in compliance with EN 50022. The connection is made via plug-in terminals. Four-terminal blocks (black) are used for the inputs. The connection of the outputs, the external bulk power and the AS-Interface is via 2-terminal blocks (output black, bulk power grey, AS-Interface yellow). The supply to the inputs and the connected sensors can be fed either from the internal supply of the module (from the AS-Interface) or via an external voltage source. A switch located on the side of the module changes the supply source. The choice of internal input supply is displayed via the INT LED. The IN and OUT LEDs display the current switching status of the relevant inputs and outputs. The OUT LED also indicates an overload or a lead breakage at the associated output. Note: The device is equipped with a communication monitor, which deactivates the outputs if the AS-Interface does not communicate with the module for more than 40 ms. The communication monitor can be deactivated via the parameter P0. Filters that suppress pulses with a duration of 2 ms or less at the inputs can be connected via the parameter P1. Parameter P2 activates a lead breakage detection system for the outputs. This function detects and reports a missing load, providing the relevant output is deactivated. The associated OUT LED and the peripheral fault function display the signal transmitted to the AS-Interface master. A signal indicating an overload of the internal input supply or the outputs is also transmitted to the AS-Interface master via the peripheral fault function. Communication via the AS-Interface continues even if a peripheral fault is set.
