ABB 5SHX08F4502 SCR control unit module
1 Introduction
The PMC916 (POWER MONITORING & CONTROL UNIT) is an intelligent
multipurpose power parameter monitoring and control device which has an
extensive range of applications in power systems. The PMC916,which can
be employed directly as a power meter, features eight switch signal channels
for the monitoring of the switch contact status. The four relay outputs of the
PMC916 allows for remote control, and alarm control by relating power
parameters as voltage, current, frequency and power,
PMC916 supports user-oriented communication protocol with opening form.
Two specifications(PMC916 and PMC916-C)support two kind of communication
ports respectively:RS485(PMC916) or CAN(PMC916-C); and support two
kinds of communication protocols respectively: MODBUS-RTU(PMC916) or
Hilon B(PMC916-C). PMC916can be connected to the communication of
computer-based monitoring and control systems conveniently.
1.1 PMC916 Internal Structure & Information Illustration
PMC916 has two MCU inside, which are defined as'DISPLAY MCU' and
"MASTER MCU'.The task of 'DISPLAY MCU' is to deal with the keyboard and
display of PMC916. 'DISPLAY MCU' and 'MASTER MCU' communicate and
exchange information by inner bus.
PMC916 input and output system include: "SWITCH INPUT", "ANALOG INPUT" and
"CONTROL OUTPUT" interface management part. The three interface management part
all exchange information and receive work & control commands from "MASTER MCU"
by inner bus.
PMC916 communicate and exchange information with monitoring and control system
by RS485/CANcommunication port, and adjust time with system clock at the same time.
