Pepperl+Fuchs introduces the VBA-4E4A-KE-ZE/R AS-Interface Module with Relay Outputs. The VBA-4E4A-KE-ZE/R extends Pepperl+Fuchs popular family of AS-Interface enclosure-mount KE I/O modules even further by delivering 4 inputs and 4 relay outputs with extended addressing in a single housing. As a result, up to 62 modules with 248 standard PNP inputs and 248 SPST relay outputs can now be on a single network.
“While most automation applications are using about twice as many inputs as outputs, making the previous solution with 4 inputs and 3 outputs a good fit, modules built to the latest AS-Interface are simply a better fit if a 1:1 ratio between inputs and outputs are needed. Certain valve control and conveyor applications come to mind,” says Helge Hornis, Ph D, Manager, Intelligent Systems Group.
Special sealed relays allow these AS-Interface modules to hold Class I Div 2 Groups A, B, C, D hazardous location approvals. Input power is switchable from internal mode where all inputs are powered from AS-Interface, to external mode where all inputs are powered externally. These AS-Interface modules feature removable, mechanical and color coded terminals, with inputs for 2- and 3-wire sensors. An M4 (3.0) master is required to use the VBA-4E4A-KE-ZE/R. “The good news is that all Gateways and PLC Scanner Cards offered by Pepperl+Fuchs satisfy this latest master specification,” explains Hornis.
