Description

ABB 1MRS750407-MBG Annunciator Unit


ABB 1MRS750407-MBG Annunciator Unit

Application     

The digital annunciator unit is used in a variety of applications requiring supervision of  alarm and signalling contacts in power plants,  substations and industrial process installations. The alarm unit is also approved for use  in off-shore installations and marine applications. Further, the annunciator unit can be  used in any application where on/off signals  are to be supervised.

The annunciator unit provides immediate  fault recognition, fault identification and  visual and audible alarm in an abnormal process situation. The annunciator unit also provides a means for subsequent fault analyses,  which means that corrective measures can be  carried out without delay and full control of  the process can be maintained. 

The annunciator units can be used either as  independent stand-alone units, or they can be  connected together via a fibre-optic bus to  form complete supervision, event sequence  reporting and data acquisition systems. The annunciator unit is a member of SPACOM, the ultimate integrated secondary  equipment system for power systems.

Features

• Flexible, field-customizable 16-channel  annunciator unit 

• Alarm channels activated by normally open  or normally closed contact 

• Four +16 output relays: two for group  realarms, one for an audible device, one  for the self-supervision system and an  additional sixteen relays for use as field  contact follower outputs or group realarm  outputs 

• Parameter selection and adjustment from  front panel or via serial interface 

• First-out alarm indication with clear fourdigit display on the front panel • Extensive data communication via the  serial interface and the SPA bus 

• Sophisticated hardware and software selfsupervision system for maximum operational reliability under the most demanding  environmental conditions • Powerful software support for parameterization of the unit via the serial interface • Member of the SPACOM product family,  ABB’s Distribution Automation systemt • CE marking according to the EC directive for EMC.

Data communication

The annunciator unit is provided with a serial  interface on the rear panel. By means of a bus  connection module type SPA-ZC 17/S or  SPA-ZC 21/S the unit can be connected to the  fibre-optic SPA bus. The bus connection  module type SPA-ZC 21/S is powered from  the host unit, whereas the bus connection  module SPA-ZC 17/S is provided with a  built-in power unit, which can be fed from an  external secured power source. The unit communicates with higher-level data acquisition  and control systems over the SPA bus.

Self-supervision

The annunciator incorporates a sophisticated  self-supervision system which increases the  availability of the device and the reliability of  the system. The self-supervision system continuously monitors the hardware and the software of the unit. The system also supervises  the operation of the auxiliary supply module  and the level of the electronics' voltages generated by the module.

If a permanent fault is detected, the fault indicator on the front panel is lit, the output relay  of the self-supervision system operates and  the outputs are blocked.

Auxiliary supply voltage

The auxiliary supply of the relay is obtained  from an internal plug-in type power supply  module. Two auxiliary power module types  are available: type SPGU 240A1 for the supply voltage range 80…265 V ac/dc and type  SPGU 48B2 for the supply voltage range  18…80 V dc. The power supply module  forms the internal voltages required by the  annunciator.
