DataTuff Single-Pair Ethernet (SPE) Cables minimize the complexity of connecting and powering edge devices while providing higher reach and bandwidth over a single twisted pair. With strong shielding and jacketing options, the Single-Pair Ethernet cables provide reliable, uninterrupted connectivity from remote field devices to the cloud, even in the harshest environments. And with Power over Data Line (PoDL) capability to consolidate data and power delivery, you can benefit from increased uptime, process efficiency and operational profit.
Belden DataTuff SPE101 is an industrial 18AWG SF/UTP PVC single pair ethernet 10Mbps cable suitable for data communications, cameras, PLCs, switches, outdoor, indoor, etc.
Why SPE, Why Now?
Industrial Ethernet protocols like Modbus TCP/IP, EtherCat, EtherNet/IP and Profinet have significantly improved communication at the routing and supervisory levels, but much of the device-to-device communication at the field/IO level has long relied on traditional Fieldbus protocols like Profibus, AS-Interface, Modbus, CANOpen, DeviceNet, CC-Link and IO-Link that typically require multiple segregated and proprietary cabling plants.
Traditional Fieldbus protocols have long been touted for their time-sensitive transfer and determinism to ensure that the right information is sent and received when and where it is needed, which is critical for communication in industrial control and automotive applications. However, the development of Time-Sensitive Networking (TSN) by the IEEE addresses these needs via time synchronization and deterministic communication over standard Ethernet.
With vast increases in the number of sensors and actuators at the field/IO level and the growing demand for more information, traditional Fieldbus protocols are quickly becoming the bottleneck within the automation environment, topping off at 10 to 12 Mbps with limited link lengths. As more links are integrated within automation systems and machinery, bulky Fieldbus cables take up too much space and come with costly and challenging installation (often in filled conduit).
With the introduction of SPE, together with TSN capability, the time is right for one standard end-to-end Ethernet network and entirely digitized communication. The end-user gains significant benefits from enabling massive amounts of sensors, actuators and I/O modules at the field level, feeding data from the field to programmable logic controllers (PLCs), manufacturing execution systems and on to the factory enterprise backbone to the cloud simultaneously in real-time.
