LIOB-591
Datasheet #89072125

L‑WEB, L‑STUDIO
The LIOB‑591 fan coil controller provides the basis for a revolutionary room auto‑
mation system based on IP, which seamlessly integrates with native BACnet/IP
networks at the controller level. Together with the L‑STUDIO software, room con‑
trol solutions can be created with little effort. Integral parts of the room control
system are a web‑based room operation via an LWEB‑802/803 dashboard and the
automatic generation of graphics for the L-PAD / L‑VIS Touch Panel for local opera‑
tion. LIOB‑591 Controllers implement the BACnet Building Controller (B-BC) pro‑
file and are BTL certified.

L‑ROC
Our room controllers provide all common interfaces and a large number of physi‑
cal I/Os for room automation projects. DALI lamps and DALI sensors are connected
to the DALI interface with an integrated DALI power supply. Up to 16 SMI sunblind
OPC motors connect to an external SMI interface. Belimo valves connect to the external
BACnet DALI OPC UA XML-DA
MP‑Bus interface. BACnet MS/TP devices connect to the RS‑485 interface, which
can also be configured as a Modbus RTU interface to connect Modbus devices like

L‑INX
energy meters or ekey finger scanners for access control or to connect the L‑STAT
Modbus MP-Bus enocean® SMI
room operator panel. EnOcean devices connect to the external EnOcean interface.
Dual Ethernet ports allow daisy chaining of LIOB-591 controllers in a ring topology
WLAN LTE SNMP
and provide BACnet/IP, Modbus/IP and OPC communication.
Optionally the LIOB-591 can communicate via wireless LAN through the
IoT LWLAN‑800 wireless adapter connected to the USB port. 20 universal I/Os, one

L‑IOB
1250 W and three 300 W TRIAC outputs connect various physical input and out‑
LIOB Local I/O
put devices. Our room automation library provides pre-built function modules for
SMS
IP
all lighting, heating, cooling, ventilation, sunblinds and access control via finger
scanners. Built‑in TSL encryption ensures secure operation of the room automa‑
tion system.

3 Add external load: Sum of max. current drawn from all outputs x 24V + power drawn from USB and L-STAT connectors
4 With high DALI traffic (e.g. during DALI-scan) increased current consumption may occur depending on the devices connected. Therefore, according to
IEC62386-101 it is recommended to take an additional current of at least 20% for dynamic processes into account in system design.
