Low-profile stainless steel AS-Interface Gateways for connection to Profibus DP are available in single or double AS-Interface network versions, suited for networking safety inputs (e-stops, door interlocks and light curtains) using AS-Interface Safety at Work.  The modular Profibus slaves are designed in accordance with AS-Interface specification 2.11 in IP20 and stand 3.25” tall with the connector attached. 
 
Feature a rugged stainless steel housing for long life and reliable operation in harsh environments; duplicate address detection to guard against incorrectly configured nodes; and a four-line graphical display for easy configuration and troubleshooting. RS232 port can be used in parallel with a running Profibus/AS-Interface network to display additional information. Ground fault detection allows the gateway to continuously monitor the integrity of the network and report undesirable ground faults to the PC or PLC. 
 
DeviceNet Gateways are the core of the wiring system, and connect AS-Interface to upper level controllers. They handle the complete data transfer, cyclically polling all participants connected to the wiring system.   The gateway can be placed anywhere in the AS-Interface segment.  The single channel version can handle 248 inputs and 186 outputs over 62 addressable I/O modules. The dual channel gateway offers 496 inputs and 372 outputs.
