ABB PMC916 Power Monitoring & Control Unit

ABB PMC916 Power Monitoring & Control Unit

PMC916 supports user-oriented communication protocol with opening form.

Two specifications(PMC916and 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/CAN communication port, and adjust time with system clock at the same time.

*Voltage & Current Measurements

Measured voltage signals are obtained through collecting and processing, and the true

RMS of 3 line_line voltage or phase voltage is displayed on the screen of PMC16.we

adopt direct input if the measured voltage is 0.4KV, and use voltage transformer as

input if the measured voltage is 0.69KV-35KV.

PMC16 allows for a voltage measurement of up to 999999V.

Measured current signals are obtained through collecting and processing, and the true

RMS of 3-phase current is displayed on the screen of PMC16.we adopt direct input if

the measured current is no more than 5A,and use current transformer as input if the

measured current is above 5A.

PMC16 allows for a current measurement of up to 32000A.

The secondary circuit current of the zero-sequence current transformer used in zero-

sequence current measurements is0.02-1A. Measured current signals are obtained

through collecting and processing, and the true RMS of zero-sequence current is

displayed on the screen of PMC16.
