B3729-H – STAR/DELTA CIRCUIT The B3729-H simulator module replicates in a scaled and simplified manner the classic star-delta switching circuit. This system is often used in practice to start large AC electric motors with heavy loads. The principle is to initially connect the motor 3-phase windings in STAR mode, thus reducing the starting current. After a few seconds the connection is changed to DELTA and the motor can then accelerate the load to its full speed. The panel includes three pushbutton switches, which are available as inputs to the PLC. The simulated switching circuit consists of four power contactors, represented by the lighting of the four LED lamps positioned close to the symbol of the contactor on the front face of the unit. The LEDs are controlled by four assigned outputs of the PLC. The condition of the four contactors can be monitored by their respective auxiliary contacts indicated on the synoptic drawing. These contacts are available as inputs to the PLC. The result of the various operations performed by the PLC is indicated by the four LEDs situated in the lower part of the board. B3729-H is supplied with a Sample Program. The students can investigate the functions of the simulator using this program, and can also develop their own programs using the software supplied with the PLC MACHINE. The unit comes complete with a sample program and an extensive instructions manual. It can also be used with any suitable PLC machine, which may already be possessed by the teaching institute. The B3729-DX should be used as an interface in all cases.

B3729-I – ROTOR RESISTANCE STARTER CIRCUIT The B3729-I simulator module replicates in a scaled and simplified manner a rotor resistance starter circuit. This system is often used in practice to reduce the overload while starting and launching large AC asynchronous electric motors. These motors have the rotor made of a winding, creating a magnetic circuit. The winding is initially connected to a (relatively) high resistance, which is progressively reduced in steps to a null value (short circuit). Due to the properties of the magnetic interaction between rotor and stator, this reduces the current required for starting. The panel includes two pushbutton switches, which are available as inputs to the PLC. The simulated starter circuit consists of five power contactors, represented by the lighting of the five LED lamps positioned close to the symbol of the contactor on the front face. The LEDs are controlled by five assigned outputs of the PLC. The condition of the five contactors can be monitored by their respective auxiliary contacts indicated on the synoptic drawing. These contacts are available as inputs to the PLC. B3729-I is supplied with a Sample Program. The students can investigate the functions of the simulator using this program, and can also develop their own programs using the software supplied with the PLC MACHINE. The unit comes complete with a sample program and an extensive instructions manual.

B3601 – INDUSTRIAL ELECTRONICS TRAINER The trainer is conceived to present a review of the characteristics and use of important industrial devices for power handling/conversion, up to application examples of special interest in comprehensive manner. The trainer consists of a collection of box-like modules, 100 x 160 x 20mm size, with a magnetic base and a printed circuit board front face. The PCB face includes the components and devices needed to perform the experiments, with clear silkprint indicating the component symbols, identities and interconnections.For the execution of the experiments the modules are placed on a metallic Base plate (430 x 310 x 30mm) where they are retained by the magnetic strips. The connections to the power supply and to the measuring instruments is by plug-in cables. Certain experiments require more than a single module to be interconnected. This is also done by plug-in cables. The magnetic latching of the modules to the metallic Base plate ensures that the various items remain steadily fixed even if the Base plate is placed vertically, as in case of collective demonstrations by the Instructor. The trainer includes an Auxiliary Module with the low-voltage DC and AC sources required to perform the experiments. This module also includes resistive and inductive loads. All the experiment modules are designed to work from the low-voltages (18-36V AC and 15 to 48V DC) for increased safety. This makes the trainer especially suitable for use by students in their early stages of training, when they have not yet gained the confidence required to work on industry-standard high-voltage systems.
