Facilitates high-speed data communication across the network
TWINSBURG, OH — Pepperl+Fuchs introduces the VBA family of I/O modules for AS-Interface specification 3.0. The entire product family is CE marked and UL listed, and supports extended addressing with 4 inputs and 4 outputs for up to 62 nodes per network. “Combined transaction” functionality allows transmission of fast analog signals, and a dedicated high-speed communications profile updates analog data at the full speed of the network. Among other benefits, it is now possible to define a “configuration channel” between I/O devices and the gateway allowing complex devices to be configured and used easily on AS-Interface.
The G2 node provides IP67 protection in a low profile flat housing, with an M12 quick disconnect I/O connection method, making it ideal for applications in the field. It includes an integrated addressing jack, with inputs for mechanical contacts or 2-, 3- and 4-wire sensors. Electronic outputs can be collectively loaded with 24 VDC and 0.5 A per output. An LED on the top of the module indicates the current switching status for each channel. Similarly, an LED is provided to monitor AS-Interface communication. LEDs also indicate AS-Interface voltage and external power supply.
The IP65 protected G4 node features input wires that can be cut to exact length in the field with vibration-resistant cage tension spring terminals for I/O connection, making it an excellent choice for harsh field conditions. Both 2-wire and 3-wire sensors, as well as mechanical contacts, can be connected to the inputs, with sensors supplied from the module. The electronic outputs can be loaded to a maximum of 24VDC and 1A per output at 24 VDC. An LED indicates the current switching status for each channel. Communication monitoring is integrated in the module – in the event of faults on the bus, the monitoring system switches off the current to the outputs.
The KE switch cabinet module is IP20 protected, with a thin 22.5mm housing for minimal enclosure space requirements. The module is quickly and easily installed by snapping on the 35mm DIN rail, and includes keyed, removable, color-coded terminals for all electrical connections. To avoid incorrect electrical connections exchanges, input and output terminals are mechanically coded. Power to the inputs and the connected sensors can be supplied via the modules’ internal AS-Interface supply or via an external voltage source. Switching is carried out by means of a switch positioned at the side of the module.
