At a Glance

This is an overview of the sensor and pre-actuator connections on TELEFAST 2 bases.

NOTE: The bases are manufactured with a general-purpose, quick-blow fuse rated 2 A. To guarantee optimum protection, this fuse should be rated according to the application (connection to input or output functions) and the maximum current allowable in the base.

Type and rating of fuse to be fitted to the base:

  • input functions: 0.5 A quick-blow

  • output functions:

    • 2 A quick-blow on the ABE-7H16S21 base

    • 6.3 A quick blow on the ABE-7H08S21 base

Connections for input and output functions.

Connecting the common for sensors:

  • In order to create the shared sensor supply, position the jumper (1) on terminals 1 and 2: terminals 200 to 215 will be on the ‘+’ of the supply (positive logic inputs).

Connecting the common for actuators:

  • In order to create the shared supply for the actuators, position the jumper (2) on terminals 3 and 4: terminals 200 to 215 will be on the ‘-’ of the supply (positive logic outputs).
