Ethernet-APL Field Switch for Hazardous Process Automation Networks
Instrava curated instruments are carefully selected to help industrial operators build stable, scalable, and future-ready process automation networks. This Ethernet-APL Field Switch is specifically designed for field-level Ethernet-APL deployment, enabling long-distance industrial Ethernet communication and PoDL power delivery without requiring an additional auxiliary power supply.
The 8-port Ethernet-APL Field Switch integrates 2 Trunk interfaces and 6 Spur interfaces into a compact industrial-grade platform, allowing seamless expansion of Ethernet-APL process networks in demanding industrial environments. The switch receives both power and data from upstream Ethernet-APL power switches through the Trunk interfaces and directly distributes PoDL power and Ethernet communication to field instruments through the Spur interfaces.
Built around IEEE802.3cg-2019 10BASE-T1L technology, the switch supports transparent Ethernet transmission for industrial protocols such as PROFINET, MODBUS TCP/IP, EtherNet/IP, CC-Link IE, and POWERLINK. This allows users to modernize legacy field networks into intelligent Ethernet-APL architectures suitable for Industry 4.0 and Industrial IoT applications.
With IP66 protection, aluminum waterproof housing, long-distance communication capability, and industrial PoDL support, this Ethernet-APL Field Switch is ideal for harsh process industries including oil & gas, chemical plants, pharmaceuticals, power generation, and water treatment systems.
Ethernet-APL Switch Description
Long-Distance Ethernet-APL Communication with Integrated PoDL Distribution
This industrial Ethernet-APL Field Switch is engineered to simplify field-level networking while reducing installation complexity and cabling costs.
The two Trunk ports receive 48–54VDC PoDL voltage and Ethernet signals directly from an upstream Ethernet-APL power switch. These Trunk interfaces support Ethernet-APL Power Classes 3 and 4, enabling stable long-distance communication and power transmission over a single twisted pair cable.
The six Spur interfaces act as powered Ethernet-APL output ports, supplying 12VDC PoDL power directly to connected Ethernet-APL field devices while simultaneously transmitting Ethernet data transparently.
Keuntungan utama meliputi:
- No auxiliary power supply required
- IEEE802.3cg-2019 compliant 10BASE-T1L communication
- Long-distance Ethernet transmission up to 1000m on Trunk lines
- Spur communication distance up to 200m
- Simultaneous data and power transmission over SPE cable
- Supports Ethernet-APL Power Classes A, C, 3, and 4
- Transparent industrial Ethernet protocol transmission
- Compact field-level Ethernet-APL expansion architecture
- Reduced wiring and installation costs
- Optimized for process automation and smart instrumentation
The switch supports cascading expansion through dual Trunk interfaces, making it highly suitable for large-scale Ethernet-APL network deployment across industrial production facilities.
Industrial IP66 Design for Harsh Process Environments
Designed for demanding industrial field applications, this Ethernet-APL Field Switch combines rugged mechanical protection with stable industrial Ethernet performance.
The device uses a durable cast aluminum waterproof enclosure with IP66 protection, ensuring reliable operation in outdoor and harsh industrial environments exposed to moisture, dust, vibration, and electromagnetic interference.
Additional industrial-grade features include:
- Wide operating temperature range from -20°C to +75°C
- Surge protection and reverse polarity protection
- Heavy-duty cable glands for industrial field wiring
- Screw-fixed installation for stable field deployment
- Industrial LED indicators for communication and PoDL status
- Long-term stable operation in hazardous process environments
Unlike conventional Ethernet switches, this Ethernet-APL Field Switch is optimized specifically for Ethernet-APL field instrumentation and SPE-based industrial communication networks. It helps operators build efficient, low-power, long-distance digital process automation systems with simplified infrastructure requirements.
The switch uses DIP switches to manually enable or disable PoDL output on each Spur interface, allowing flexible field power management for Ethernet-APL instruments and sensors. Users should ensure connected field devices comply with Ethernet-APL standards and support 9–15VDC PoDL input specifications.
