TEWS TPMC81

Single-width 32-bit PMC module ARCNET Interface Flexible Media Interface isolation RS485 interface Tews Technologies TPMC815 ARCNET interface module is a standard single-width 32-bit PMC module. The device uses controller COM20020 to provide complete ARCNET interface. The module has two interface types :TPMC815-11 provides the traditional isolated hybrid interface, and TPMC815-21 provides the isolated RS485 differential driver interface. The TPMC815 is ideally suited for industrial/factory automation and automotive applications.

The controller (English name :controller) refers to the main command device that changes the wiring of the main circuit or control circuit and changes the resistance value in the circuit to control the starting, speed regulation, braking and reverse of the motor in a predetermined order. It is composed of program counter, instruction register, instruction decoder, timing generator and operation controller. It is the “decision-making mechanism” that issues commands, that is, it completes the operation of coordinating and directing the whole computer system.
