Details: VBA-4E2A1A-KE3-ZEL/E2L/SEL


The AS-Interface safety output module VBA-4E2A1A-KE3-ZEL/E2L/SEL is a control cabinet module with two safe electronic outputs. The outputs are dependent on a common safe release circuit, but they can be switched separately from each other by conventional output bits as long as the release from the safety monitor is present. In addition, the module has an A/B node for diagnostics and a second A/B node for the connection of three conventional inputs and the contactor feedback circuit EDM.

The housing is only 22.5 mm wide and takes up little space in the switch cabinet. A snap-on function mounts the module onto the 35 mm mounting strip in line with EN 50022.
An addressing socket is integrated into the module. Access to the addressing of the safe output and the integrated A/B nodes is done by switching the programming switches.

The connection is made via plug-in terminals. Four-way (black) terminal blocks are used for the inputs. The AS-Interface is connected via a two-way terminal block (yellow). This allows the sensors or the power supply to be easily separated for commissioning or service. Power is supplied to the inputs and connected sensors by an external auxiliary power supply. Yellow LEDs display the current switching status of the inputs and outputs. The red LED FAULT displays communication errors and indicate that the A0 output bit is set. A green LED ASI displays the operating voltage and the address 0.
