Description
The TELEFAST
®
SB2 AS-i intelligent interfaces are based upon the TELEFAST 2 concept. They allow
standard discrete sensor and actuator devices to be connected to the AS-i bus. They are available in 4
or 8 I/O versions. Their inputs, depending upon the model, may be isolated from the AS-i bus. Their
outputs (either solid state or electromechanical relay) may be used to control actuators of 1 to 5 A.
Composition of the TELEFAST SB2 intelligent interfaces
Configurations
Eight versions of TELEFAST SB2 intelligent interfaces are available as follows:
• 8-channel interfaces
Four versions available, incorporating 4 inputs and 4 outputs.
ABE8S44SBB0
— The inputs, isolated from the AS-i bus, are powered by an external 24 Vdc supply. They are protected by a current
limiter.
— The solid state outputs, isolated from the AS-i bus, are powered by an external 24 Vdc supply.
ABE8S44SBB1
— The inputs are powered from the AS-i bus and protected by a current limiter.
— The solid state outputs, isolated from the AS-i bus, are powered by an external 24 Vdc supply.
ABE8R44SB11
— The inputs are powered from the AS-i bus and protected by a current limiter.
— The electromechanical relay outputs with 1 N/O contact, isolated from the AS-i bus, are powered by an external
5 to 125 Vdc or 5 to 250 Vac supply.
ABE8R44SF10
— The inputs, isolated from the AS-i bus, are powered by an external 110 Vac supply.
— The electromechanical relay outputs with 1 N/O contact, isolated from the AS-i bus, are powered by an external
5 to 125 Vdc or 5 to 250 Vac supply.
• 4-channel interfaces
Four versions are available, incorporating 4 inputs, 4 outputs or 2 inputs/2 outputs.
ABE8S40SB00
— Interface with 4 inputs powered by the AS-i bus and protected by a current limiter.
ABE8R04S010
— Interface with 4 electromechanical relay outputs with 1 N/O contact, isolated from the AS-i bus, and powered by
an external 5 to 125 Vdc or 5 to 250 Vac supply.
ABE8S22SBB1
Interface with 2 inputs and 2 outputs.
— The inputs are powered from the AS-i bus and protected by a current limiter.
— The solid state outputs, isolated from the AS-i bus, are powered by an external 24 Vdc supply.
ABE8S22SBB2
Interface with 2 inputs and 2 outputs.
— The inputs are powered from the AS-i bus and protected by a current limiter.
— The solid state outputs, isolated from the AS-i bus, are powered by an external 24 Vdc supply.
NOTE: The outputs have an inverse operation:
- state 0 when they are controlled
- state 1 when deactivated
In the case of a bus failure, the default position is state 1.

All the TELEFAST SB2 interfaces share certain common functions and
features, as shown below:
1. Module address connector
2. "Normal"/"Addressing" mode selector switch
3. LED (green) indicating correct connection to AS-i bus
4. LED (red) indicating an I/O fault
5. LED (green) indicating presence of external power supply (only on
ABE8S22SBB• and ABE8S44SBB•)
6. Removable screw terminals for I/O connection and external power
supply, if required
7. Channel marking label
8. LED showing I/O status
9. Removable screw terminal block for connection to the AS-i bus
10. Add-on terminal blocks (ABE7BV10 and ABE7BV20) for additional
common
