BACNET, LON, MODBUS TERMINATOR
L-TERM SERIES
DESCRIPTION
The LON TP/FT-10, TP/LPT-10, TP/XF-1250 and BACnet MS/
TP networks need to be terminated using a defined network
terminator.
L-Term LT-03 offers one standard network terminator for a
TP/FT-10 or TP/LPT-10 channel. In addition, LT-03 comes
with a network access connector for a simple and reliable
connection to the CEA-709 network e.g. for maintenance or
analyzing the network locally.
L-Term LT-13 and LT-33 offer two standard network
terminators in a slim housing which makes them a perfect
solution for LOYTEC active network infrastructure products
(e.g. L-IP, L-Switch, L-Proxy etc.) at a very competitive price.
L-Term LT-04 and LT-B4 offer one standard network
terminator for a EIA-485 channel such as BACnet MS/
TP, Modbus or TP/RS-485 (CEA-709). LT-04 comes with
a network access connector for a simple and reliable
connection to the network e.g. for maintenance or analyzing
the network locally. The LT-B4 is a bus termination with
biasing circuit (failsafe biasing) and needs a power supply.
This biasing circuit draws the level of the bus in standby mode
(idle) to a safe value (logic "1").
FEATURES
• BACnet, Modbus and LON models available
• Supports bus and free topology termination (LT-03,
LT-13, LT-33)
• TP/FT-10 side can also be used to terminate link power
channels
• Pluggable screw terminals (0.5 - 2.5 mm²)
• DIN-rail mountable
Supply Voltage 24 VAC/VDC ± 10%
