Application
Characteristics
The bus connection unit 560BCU02 is designed to make the RTU560 System Bus Signals accessible to the outside on the communication sub-rack 23TP22 or the 560MPR01 if a 560CMU05 subrack is used.
The bus connection 560BCU02 may be used in the 23TP22/560MPR01. The board is mounted to the plug-in terminal strips of the existing slots. This gives the chance to use two RTU560 boards at these slots.
ALARM (ALR) and WARNING (WRN) are signalled to the outside with relay contacts.
The power comes from the RTU560 boards and a 24V cable.
An external minute impulse may be connected via an optocoupler. The filtered internal minute impulse is outputted as 24V impulse.
The signals ALARM and WARNING are distributed with relay contacts. On signalling ALARM the signal WARNING is activated also.
The 560BCU02 can be used in either the 23TP22 or the 560MPR01. With this board two RTU560 communication boards are usable within the 23TP22 or 560MPR01.
ALARM and WARNING are supervised from a watchdog. They are activated if the communication modules do not respond within 30 seconds. At the isolated minute impulse input TSI, an external minute impulse can be connected to the RTU560 boards. This minute impulse is evaluated from the time master function. The internal filtered minute impulse is available at the minute impulse output TSO.
