June 24, 2010 - Pepperl+Fuchs introduces the VBA-4E4A-KE-ZE/R AS-Interface Module provides 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.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.
