AS-Interface slaves

(I/O modules) for

use in cabinets

Slimline modules

Compact distributed configurations in a

control cabinet are possible with the

Slimline model available with degree of

protection IP20. The modules can be

clipped onto a DIN rail or screwed to a

back plate like any other low-voltage de-

vice in a control cabinet.

In the SlimLine series, the SlimLine

S22.5 and S45 variations are available,

and can be supplied with either screw

terminal or cage clamp connection. With

the cage clamp connection method, the

cables are clamped through a cage-type

spring terminal without screws; this pro-

vides added advantages for use in areas

where vibration or shock may be a prob-

lem for designers.

Load feeder modules

The control circuit of a

load feeder module can

be fully pre- wired with

the AS-Interface load

feeder module. This

range has been optimised

for applications which in-

clude the SIRIUS® 3R

load feeder modules sizes

S00 and S0.

Four different AS-Interface load feeder

modules are available. Direct and re-

versing starters, as well as double direct

starters and starter combinations for

pole switchover can be wired with

them. The feedback signals from the cir-

cuit-breakers and contactor(s) can be

scanned at the inputs. The outputs are

used for direct control of the contactor

coils.

LOGO! Minicontroller

With the AS-Interface module it is pos-

sible to operate the LOGO! as an intel-

ligent slave in all AS-Interface applica-

tions. With its local inputs and outputs,

logic combinations, and timer functions,

the LOGO! is the only slave to provide

distributed controller functionality on the

AS-Interface network. Moreover, it is

possible to set parameters (e.g. timer

and setpoints) using the integrated key-

board and display, and to change them

without additional devices.

The LOGO! is therefore designed for ap-

plications in where higher-level automa-

tion systems are integrated with simple

decentralized automation tasks, e.g. for

access door controls. By having decen-

tralized control it again offers the de-

signers the benefit of localized control

should the higher-level control system

fail.
