Detailed data
ABB 89AR30 Modules of the Turbine Control System
The relay unit is designed primarily to activate the trigger control element of the protection system.
It is mounted in a standard removable compartment, in accordance with DIN standards, using 3 units, including F-type female connectors.
The module contains six relays, three of which can be wired according to user-specific needs. The contacts of the other relays are wired in 2-out-of-3 mode.
The module contains prototype-tested relays*) with positively driven contacts. The contacts of relays K1, K2, K3 are divided into two circuits and connected in a 2-out-of-3 sequence according to the open-circuit principle (external jumpers B18-B20).
Auxiliary contacts can be used to query the position of individual relays.
Relays K4, K5 and K6 can be used freely. For example, K4 can be used for an emergency disconnect button for a specific protection circuit based on the closed circuit or open circuit principle. In this case, the required jumper needs to be placed on the edge connector.
