Product Description:

The FC7502 Lightbus Card produced by Beckhoff Technologies operates as a device for SERCOS fieldbus systems. The PCI bus interface of this industrial automation device enables direct transmission with PC systems. Two independent SERCOS fieldbus channels operate from the card to provide reliable data transfers. Each bus channel from this device allows up to 254 connected bus systems.

The FC7502 lightbus card functions through data transfer speeds that users can set at 2, 4, 8, or 16 MBit/s. The system needs to determine which transfer rate should be selected through this interface. The bus interface requires four FSMA connectors, which function according to IEC 874-2 specifications. The fiber optic connections remain stable and secure because of these connectors. The synchronization of multiple cards can be achieved through a ribbon cable. The synchronization option allows different units to function together with unified operations. One LED indicator serves as the hardware diagnostic tool for each channel's availability. Each channel status can be checked using the built-in LED display. Users can access TwinCAT I/O drivers as well as higher driver levels through the FC7502 lightbus card. The PCI connection through Plug and Play serves as an interface for PC use and provides 32-bit system access.

The FC7502 lightbus card includes an interface that grants immediate access to DPRAM and SERCON816 register operations. The regulation of the SERCOS interface defines the minimum cycle time to be 62.5 microseconds. Operation of the card stays uninterrupted when used in environments that measure between 0 and 55 degrees Celsius. The standard PCI bus power usage for the card includes 285 milliamps. The dimensions are extended to 95 millimeters in height while reaching 120 millimeters in width. Standard PC slots welcome this product because it fits well within its compact measurements.
