3 Functions and features

The AS-i FO repeater is used to extend the cable of an AS-i network� The

incoming data of repeater 1 is processed and transmitted to repeater 2 via a fibre

optic cable� The data of repeater 2 is also processed and sent to repeater 1� A

system consists of two AS-i FO repeaters�

• Electrical separation of the incoming AS-i line from the outgoing AS-i line

• Additional AS-i power supply required

• Connection via supplied COMBICON connectors

• Use of a standard fibre optic cable with ST connector

4 Operating and display elements

1� COMBICON connector with cage clamps

2� Panel for labelling

3� Connection fibre optic cable with ST connector

4� DIN rail adapter

5 Installation

5.1 Installation of the device

►Mount the device on a 35 mm DIN rail�

►Leave enough space between the device and the top and bottom of the control

cabinet to enable air circulation and to avoid excessive heating�

►Take into account the internal heating of all devices when mounting several

devices side by side and observe the environmental conditions for every

device�

5.2 Remove device

6 Connections

6.1 Electrical connection

Connect the incoming AS-i line 1 to terminals A+ and A- of repeater 1 and the

outgoing AS-i line 2 to terminals A+ and A- of repeater 2�

AS-i Line 1 AS-i Line 2

An additional AS-i power supply is required for the outgoing AS-i line�

If the AS-i FO repeater 1 is at the cable end of an AS-i line and the cable length is

> 100 m, the AS-i bus must be terminated with a link between T1 and T2� A link is

supplied�

The AS-i bus termination is used to improve the signal quality and to extend the

AS-i network cable� Only one AS-i bus termination may be used per AS-i segment�

Activate the termination and check the signal quality of the AS-i network via the

diagnostic possibilities of the master (e.g. telegram error).

6.2 Optical fibre connection

►Connect fibre optic cable�

►Connect Rx of repeater 1 to Tx of repeater 2,

connect Rx of repeater 2 to Tx of repeater 1�

Permissible fibre optic cable types

- Fibre optic cable 50/125 µm with ST connector (recommended up to 500 m)

- Fibre optic cable 62�5/125 µm with ST connector (do not use at distances

below 200 m)

►Observe permissible bending radii of the fibre optic cable manufacturers�
