The Schneider Electric LULC031 is a 24 V DC Modbus communication module designed for TeSys U motor starter-controller assemblies. It provides remote monitoring and control through a multidrop RS485 interface using the Modbus RTU protocol, with an RJ45 connection and selectable addressing from 1 to 31. The plug-in module is compatible with LUB non-reversing and LU2B reversing power bases, together with suitable LUCA, LUCB, LUCC, LUCD, LUCL and LUCM control units. It supports operating-state, alarm and fault monitoring, remote reset and motor-load information, depending on the connected control unit. Three front-panel LEDs provide clear local status indication, while dedicated outputs support starter-controller coil operation. Rated IP20, the LULC031 operates at temperatures from -25°C to +55°C and is intended for straightforward integration into industrial motor-control and automation systems.

What type of component is this?
The LULC031 is a plug-in Modbus communication module designed to connect a TeSys U starter-controller assembly to an industrial communication network.
Which communication protocol does the module use?
It communicates using Modbus RTU over an RS485 multidrop physical interface.
What supply voltage is required?
A 24 V DC auxiliary supply is required for correct operation. The connected TeSys U control unit must also be a compatible 24 V DC model.
How does the module connect to the Modbus network?
The network connection is made through an RJ45 connector located on the front panel.
What communication speeds are supported?
The module can recognise communication rates of 1,200, 2,400, 4,800, 9,600 and 19,200 bit/s. Its factory communication setting is 19,200 bit/s.
What addressing range can be used?
Device addresses from 1 to 31 can be selected using the module's microswitches. Address changes are applied when the communication module is powered up.
Which TeSys U assemblies are compatible?
The module is intended for TeSys U LUB non-reversing and LU2B reversing power bases. It supports compatible LUCA, LUCB, LUCC, LUCD, LUCL and LUCM 24 V DC control units.
What information can be accessed remotely?
Available information depends on the fitted control unit and can include ready, running, alarm and fault states, motor load indication, fault identification and operating data.
Can the starter-controller be operated remotely?
Yes. The LULC031 supports remote on and off commands, output control and selected reset functions through Modbus, subject to the capabilities and configuration of the associated control unit.
How many outputs does the module provide?
It has three outputs in total. Two are dedicated to starter-controller coil operation, while the third is a programmable digital output.
What is the output switching capacity?
The outputs have a switching capacity of 0.5 A at 24 V DC. Appropriate external circuit protection and correct wiring must be used.
What do the front-panel indicators show?
Three LEDs provide local status information. They indicate Modbus communication activity, communication or internal faults, and the presence of 24 V DC on the output circuits.
What happens if communication with the controller is lost?
Configurable fallback behaviour can hold the outputs in their previous state, force a stop, retain the commanded state or force operation in a selected direction. The required response is selected through the module's registers.
What is the operating temperature range?
The specified ambient operating temperature range is -25°C to +55°C.
What level of ingress protection is provided?
The module is rated IP20 in accordance with IEC 60529, making it suitable for installation within an appropriate industrial enclosure.
How is the module installed?
It plugs into the front of the compatible TeSys U power base beneath the 24 V DC control unit. The control unit locks the communication module into position.
What is the approximate weight?
The module has an approximate net weight of 0.08 kg.
