VBA-2E-KE4-ENC-S

Safe AS-i module for encoders

Descripción

The AS-Interface rotational speed monitor VBA-2E-KE4-ENC-S is a safe control cabinet module with 2 inputs. The inputs comprise 2 safe inputs for incremental encoders. The rotational speed monitor monitors the standstill, rotational speed and direction of rotation on a maximum of two axes and sends a safe signal via the AS-Interface network when a value falls below the set threshold. The housing, which is only 22.5 mm wide, requires little space in the switch cabinet. The module is installed by simply snapping it onto the 35 mm standard mounting rail to EN 50022. An addressing socket is integrated in the module. The AS-Interface and external power supply are each connected by means of a 2-station terminal block. This permits the simple removal of the supply during commissioning or servicing. The supply to the rotary encoders is fed either internally via the module from the AS-Interface or via an external supply. The current status of the inputs is indicated via yellow LEDs. Communication faults are indicated via red LEDs. The display of the operating voltage and the address 0 is provided by a green LED. The configuration data is saved on a chip card, making it easier to replace the module in the event of damage.
