Centralized fault indication with 1 continuous indication

Application

• formonitoring control and regulating systems
• facilitates locating and repair of faults
• used in heating, air conditioning and ventilation systems
• can be used in manufacturing processes as well as in building installations

  Function and design

  Incoming interference triggers a relay which remains excited until all interference inputs are isolated. An alarm or LED display can be connected at the changeover contact. Terminal Bz is the reference point for the electronic equipment and the neutral conductor of the interference input voltage.

  Note:

  Terminals N and Bz must be connected via jumper before start-up. Pulses <100ms will not be recognized.

  Expansion module to 87.030.1053.0

  Up to 91 additional interference inputs can be connected at the basic module (terminal 8).
