VAA-4E4A-KE5-ZEJQ/R 269780 Pepperl+Fuchs Module

The AS-Interface connecting module VAA-4E4A-KE5-ZEJQ/R-KRO is a switch cabinet module with 4 inputs and 4 relay contact 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+ and AS-i-, two connections are available in each case, these connections are bridged in the terminal block. In case of i-, terminals 5 and 6 as well as 7 and 8 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 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. 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 the AS-Interface synchronous mode. Installation, Commissioning, and Maintenance: Install the device in a closed electrical plant where only electricians or persons with appropriate electrical training have access. The relevant laws, guidelines, and standards that apply for the application or intended use must be observed. The device must be installed in a switch cabinet or switch box that meets degree of protection IP54 as a minimum. Additional requirements for the AS-Interface power supply: If voltages that are not in accordance with PELV/SELV are connected to the relay contact outputs, then it must be ensured that the AS-Interface supply voltage does not exceed 36 V, even in the event of a fault. Daisy-Chaining Devices: Insulation to the outer surfaces of the housing: Basic insulation in accordance with EN 60664-1. To provide reliable and double insulation, devices in the direct vicinity must have basic insulation as a minimum.
