VAA-4E4A-G11-ZAJ/EA2L-F 220205 Pepperl+Fuchs Module

The 0-902-26-874-7 is an AS-Interface switch-on module with 4 inputs and 4 outputs. Both 2, 3 and 4-wire sensors as well as mechanical contacts can be connected to the 4 positive switching 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 sensors/actuators is via an M12x1 plug-in connection on the top side of the device. The AS-Interface flat cable and external power supply are connected to the underside of the module via insulation piercing technology. The inputs and the connected sensors are powered by the internal power supply of the module (from the AS-Interface). The outputs and the connected actuators are powered by an external voltage source (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 activated via the parameter P1. The 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.
