VBA-4E4A-KE5-ZEJQ/E2L

AS-Interface sensor/actuator module

Opis

Cabinet module. 4 inputs and 4 outputsfa. The AS-Interface connecting module VBA-4E4A-KE5-ZEJQ/E2L is a switch cabinet module with 4 inputs and 4 electronic outputs. The housing is only 19 mm wide and takes up little space in the switch cabinet. The module is mounted by snapping onto the 35 mm DIN rail in compliance with EN 50022. The connection is made via removable 4-pin push-in terminal blocks. For AS-i+, AS-i-, AUX+, and AUX-, two connections are available in each case; these connections are bridged in the terminal block. If the terminal block is disconnected from the module, the link between these connections is retained. The terminal blocks for the inputs and outputs are mechanically coded. 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 UEXT voltage source. A switch located on the side of the module changes the source. The internal input supply is displayed via the INT LED. The relevant IN and OUT LEDs display the current switching status of the inputs and outputs. The OUT LEDs also indicate an overload or a lead breakage at the corresponding output. Safety Applications. The module offers safe galvanic isolation between the output part supplied by AUX and the other circuit components. As such, it can be used in applications that require reliable switch-off of the AUX power supply for EMERGENCY STOP functions up to safety classification PLd via an external switching element. Details of the conditions that apply in this case can be found in the "Notes" section of the original instructions. Notes:. 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 provides a visual indication of the missing load, and the 'peripheral fault' function reports it 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.
