Pepperl+Fuchs VAA-4E4A-G11-ZAJ/EA2L-FV1-Y 220224

The VAA-4E4A-G11-ZAJ/EA2L-FV1 is an AS-Interface switch-on module with 4 inputs and 4 outputs. 2, 3 and 4 wire sensors can also be connected as mechanical contacts to the 4 sourcing electronic inputs. The 4 electronic outputs are overload and short-circuit protected. The housing with a central screw enables fast mounting on the base plate. The connection to the AS-Interface cable, to the external power supply and to the sensors/ actuators is via M12x1 plug-in connections on the top side of the device. You can also make the connection to the AS-Interface and to the external energy supply with insulation piercing technology via an AS-Interface flat cable on the underside of the module. The inputs and the connected sensors are powered by the internal supply of the module (from the AS-Interface). The outputs and the connected actuators are powered by an external voltage source (from the AUX). The current switching state of each input and output is indicated via an IN or OUT LED. The OUT LED also indicates an overload or a lead breakage at the associated output. The AS-i/FAULT LED indicates the status of the AS-Interface (normal operation, communication error, peripheral fault, address 0). The AUX LED indicates the external power supply. The switch-on module is compatible with AS-Interface POWER24. 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. An overload of the input supply or the outputs is also reported to the AS-Interface master via the 'peripheral fault' function. Communication via the ASInterface continues even if a peripheral fault is set.
