VBA-2E2A-KE4-ENC/SSI-S
Safe AS-i module for encoders
Description
AS-Interface safety module VBA-2E-KE4-ENC/SSI-S is a safe switch cabinet module with two safe inputs and two safe electronic outputs. The inputs can be used to connect devices such as incremental rotary encoders or absolute rotary encoders using SSI, sin/ cos, or TTL interfaces. The main functions of the safety module are: position monitoring, monitoring the speed range and deceleration ramp, safely switching off drives, and providing a safety logic for applications involving up to two axes (STO, SS1, SS2, SLS, SLP, SDI, SCA, etc.). The housing is only 22.5 mm wide and takes up little space in the switch cabinet. A snapon function mounts the module onto the 35 mm mounting strip in line with EN 50022. An addressing socket is integrated in the module. The AS-Interface and the external power supply (AUX auxiliary voltage) are each connected via a two-way terminal block. This configuration allows the power supply to be easily separated when commissioning or servicing. The AUX auxiliary voltage is used to supply power to the outputs. The rotary encoders are supplied with power independently of the safety module. Yellow LEDs display the current status of the inputs. Communication faults are indicated by red LEDs. A green LED displays the operating voltage and the 0 address. A chip card stores the configuration data and makes it easy to change the module in case of damage.
