SCHNEIDER ELECTRIC VW3A8306TF03

Schneider Electric Modbus T-Connector VW3A8306TF03 Description The Schneider Electric VW3A8306TF03 is a passive T-junction designed for creating tap-offs on a Modbus serial link. It is an essential accessory for building or expanding industrial communication networks, particularly for connecting devices like Altivar frequency drives. This unit features a rugged metal housing for durability in industrial environments and includes an integrated 0.3-meter cable with a male RJ45 connector, along with two female RJ45 ports for daisy-chaining or creating a branch. Specifications Manufacturer: Schneider Electric Part Number: VW3A8306TF03 Product Type: Modbus T-Junction / Tap-off Bus Type: Modbus Cable Length: 0.3 meters Electrical Connection: 1 male RJ45 connector, 2 female RJ45 connectors Housing Material: Metal Label Info Brand: Schneider Electric Model: VW3A8306TF03 Description: MODBUS T 0.3m Application This T-connector is widely used in automation systems to connect Modbus-enabled devices such as frequency converters (e.g., Altivar series), PLCs, and HMIs. The short cable length is perfect for creating clean, short-stub connections directly at the device, adhering to best practices for network topology. Country of Origin This product is manufactured by Schneider Electric in China. CO2 Impact By purchasing this reused item, you contribute to a circular economy and avoid approximately 3.2 kg of CO2 emissions that would be generated from manufacturing a new one. This saving is comparable to the emissions from driving a standard car for 16 kilometers. Availability This item is in stock and ready for immediate dispatch.

FAQ What are the red and blue buttons for on the VW3A8306TF03?The red and blue buttons are used to activate or deactivate the Modbus line termination resistor. This is critical for maintaining signal integrity. The terminator should only be activated on the two devices at the physical ends of the Modbus network segment. Can this T-connector be used for standard Ethernet networks?No, this connector is specifically designed and wired for Modbus serial communication over RJ45. While it uses the same physical connector as Ethernet, the pinout and electrical characteristics are different. Using it for Ethernet will not work and could potentially damage equipment. What is the primary application for this 0.3m cable length version?The short 0.3-meter cable is ideal for creating a tap-off directly at the device port, such as on an Altivar frequency drive. It minimizes cable clutter and signal degradation by keeping the stub length on the network trunk as short as possible, which is a best practice for Modbus network topology. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
