Motorised rollers form the backbone of many conveyor lines. With new ASi-5 motor modules for the EC5000 BI from Interroll, Bihl+Wiedemann is addressing decentralised control including additional diagnostic data. The focus of the trade fair appearance in Stuttgart is on compact design, digital communication and reduced wiring.
Transparency and simple integration are becoming increasingly important in conveyor systems with high cycle rates and a growing number of variants. Bihl+Wiedemann is expanding its portfolio of ASi-5 motor modules to include cable duct variants for the 24 and 48 volt EC5000 BI motorised rollers from Interroll.
The BWU5178, BWU5208 and BWU5209 modules differ in the number and voltage of the connectable drives: the BWU5178 can operate two 24 V motorised rollers, while the BWU5208 can control four 24 V rollers and the BWU5209 four 48 V rollers. The system therefore covers different performance requirements in sorting and conveying applications.
Additional data via bus interface
Communication with the rollers takes place digitally via the bus interface. According to the company, this allows additional information such as drive temperature or current consumption to be read out in addition to pure control. For operators, this means greater transparency regarding the status of individual zones - a prerequisite for condition-based maintenance and rapid fault localisation.
The modules are designed with IP54 protection and are connected to the motorised rollers via M8 snap-in cable sockets. The connection to ASi and AUX is made using penetration technology and profile cables, which should reduce the installation effort in widely branched conveyor lines.
Integrated I/O for sensors
In addition to the motor connection, the modules offer additional digital inputs and outputs. The BWU5178 has four digital inputs, while the BWU5208 and BWU5209 each have eight. This means that light barriers or other sensors can be connected directly without having to provide separate modules, for example.
The combination of motor control, diagnostic access and integrated sensor technology is aimed at compact, decentrally structured conveyor segments. Especially in retrofit projects or modular system concepts, the reduced variety of hardware can help to simplify planning and commissioning.
