ABB Electrical 1SVR550111R1100 Off Relay w/ Auxiliary Supply Time Relay

Model Type: CT-AHE Electrical 1SVR550111R1100 Off Relay w/ Auxiliary Supply Time Relay

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

The CMU reads the time and date via the RTU system bus.

If the GPS signal is interrupted, the clock on the 560RCR01 will continue to operate.

The clock on the 560RCR01 will continue to operate using a high precision quartz clock. The built-in battery allows the

The built-in battery allows the 560RCR01 to continue to operate (≥ 10 years), even when the RTU station is turned off.

Continued operation (≥ 10 years) even when the RTU station is turned off. Upon power-up

The RTU560 enters the valid time immediately.
