Concept
Twisted Pair Adapter
SpaceLogic™ Twisted Pair Adapter - Ethernet (TPA-E) connects to the SpaceLogic BACnet/IP controller and automation server via Ethernet 10/100 Mbit (IEEE 802.3) and utilizes existing twisted pair cabling originally used for legacy serial and free topology protocols. This enables seamless integration of existing twisted pair networks into the IP-based infrastructure of the EcoStruxure Building Management System (BMS), reducing installation costs and simplifying the transition from legacy systems, such as LonWorks FTT-10 networks, to the EcoStruxure BMS network.
Twisted Pair Adapter is designed for integration with EcoStruxure BMSs.
The adapter reduces engineering effort by requiring little to no configuration.
The adapter supports free topology networks, including bus, star, ring (loop), daisy-chain, and hybrid (mixed) network topologies.
The adapter supports Ethernet connectivity at 10/100 Mbit/s. Actual data throughput may vary depending on the type and length of the transmission medium.
The device has an Ethernet 10/100BASE-TX port with RJ45 connector for connection to the SpaceLogic BACnet/IP controller or automation server and a 2-position removable screw terminal block for polarity insensitive connection to the twisted pair cable network.
The adapter is designed for scalability with support for up to 64 nodes (adapters) per twisted pair cable and cable lengths up to 1200 m (3900 ft).
The device can be powered by a standard 24 VAC or 24 VDC power supply.
The device is designed for installation on a DIN rail with a width of 1.5 units (27 mm or 1.1 inches). The device can also be installed on a wall or flat surface.
Ethernet over Twisted Pair Cable Network
Twisted Pair Adapter supports Ethernet over twisted pair cable networks.
For more information, see Ethernet over Twisted Pair Cable Network .
Twisted Pair Adapter Power Supply
The Twisted Pair Adapter supports power input from either a standard 24 VAC or 24 VDC source.
For more information, see Twisted Pair Adapter Power Supply .
Twisted Pair Adapter Supported Communication Standards
As a protocol-agnostic device, the Twisted Pair Adapter supports various IP-based protocols, including BACnet/IP, and BACnet/SC (Secure Connect), used in the EcoStruxure BMS network.
Twisted Pair Adapter Screw Terminals and Port
The Twisted Pair Adapter is equipped with the following connectors:
4-position removable screw terminal block (Power input)
2-position removable screw terminal block (NET)
RJ45 port labelled Ethernet 10/100
For more information, see Twisted Pair Adapter Screw Terminals and Port .
Twisted Pair Adapter LEDs
There are three LEDs on the front of the Twisted Pair Adapter. The LEDs indicate different types of status and modes.
For more information, see Twisted Pair Adapter LEDs .
Twisted Pair Adapter Button and Switch
The Twisted Pair Adapter has two controls on the front:
Push-button labeled “INIT”
2-pole slide switch with positions labeled “M” and “T”
For more information, see Twisted Pair Adapter Button and Switch .
Twisted Pair Adapter Operating Modes
The operating modes are controlled by the M/T slide switch on the front of the adapter:
Master – For connection to an automation server (only one Master per network).
Terminal – For connection to a SpaceLogic BACnet/IP controller.
For more information, see Twisted Pair Adapter Operating Modes .
Twisted Pair Adapter Device Installation
The Twisted Pair Adapter can be installed on a DIN rail or other flat surface inside a cabinet. The device is recommended to be installed in a cabinet, unless local regulations allow an exception.
