ABB Electrical S271-K4 240V AC Circuit Breaker

Model Type: S 271 Electrical S271-K4 240V AC Circuit Breaker

Application

The remote terminal unit RTU560 can be synchronized with time information received from Global Positioning System (GPS) satellites via module 560RCR01.

The RTU560 reads the time and date from the module 560RCR01 and synchronizes its internal time with standard time via minute pulses.

The RTU560 synchronizes its internal time with standard time by means of minute pulses.

Using the module 560RCR01 ensures that process information from multiple end devices, if it contains time information, is synchronized.

Features

GPS signals can be reliably received in the following situations

The antenna is mounted in a position where at least one satellite can be received. Under normal conditions

it can receive four satellites. When the

the antenna is mounted on top of a building so that it can “see” most of the sky.

The GPS receiver calculates the position of the satellites as it receives their signals and

synchronizes with the GPS as it receives information from the satellites.

information from the satellites. Once it has calculated its position

it begins to synchronize the RTU by

generating minute pulses and sending the absolute time

absolute time to the RTU560 CPU via the RTU system bus.

The communication unit (CMU) synchronizes itself to the

MIN1 via the leading edge of the minute pulse.

The CMU reads the time and date via the RTU
