B3510B3510-W – LINEAR MOTOR

General:

–

The B3510-W module includes an on-board stepping linear actuator and the electronic drive circuit to allow the experimentation and investigation of the basic characteristics of the motor. The motor is provided with a position indicator, this facilitates the study of motor positioning, take-in point, loss of step.

The B3510-W module comes complete with a connection cable kit, 2 software packages and an extensive instructions manual. The two software packages are respectively running under DOS and Windows operating systems. on IBM or compatible machines.

The electronic section includes a phasesignal generator and power drive stage. The motor can be operated manually in singlesteps or sequentially from an on-board clock generator. The module also includes a PC data link for full remote operation. A software package is provided with the trainer for this purpose. The clear component layout and rugged construction renders this unit particularly ideal for the most demanding of classroom conditions.

B3510B3510-Z – PC INTERFACE MODULE

General:

EPROM and respectively 64k and 64kbits expandable to 256+256k Universal Synchronous/Asynchronous Receiver Transmitter to implement a serial data link with the host PC 8 analog inputs, with multiplexer and A/D converter. The analog inputs are jumper-programmable to operate in the range 0-5V, 0-10V, -10 to +10V 8 digital inputs, TTL level 8 analog outputs, with D/A converter and demultiplexer. The analog outputs are jumper-programmable to provide levels in the range 0-5V, 0-10V, -10 to +10V 8 digital outputs, with open-collector transistors

The B3510-Z module performs a multiple teaching function within the B3510 series of trainers The unit demonstrates the architecture and organization of a microprocessor-based control system, which may be interfaced with the other trainers of the series to produce more complex systems. The trainer is used in conjunction with a PC, and creates an intelligent interface to the experiment modules, for the purpose of collecting data, pre-setting analog and digital outputs and sampling input terminals. It can also be used as a general-purpose microcomputer system to experiment software developed by the students. The B3510-Z is a module having all the components visible and accessible from the front face. The clear component layout and rugged construction renders this unit particularly ideal for the most demanding of classroom conditions.

Features: Microcomputer unit, based around a CMOS microprocessor of the Z80 family, the Z84C00-06. RAM and
