Function And Features - Ifm Electronic Ac2526 Notice De Montage

Function and features

The slave converts analogue input signals and transfers them to the
AS-i master via the AS-Interface. The AS-i module operates as a slave
with bidirectional data transfer in the AS-i network.
The data transfer to the host is asynchronous according to the AS-i pro-
file S-7.3 and the AS-i specification V2.1.
• Current measurement 4 ... 20mA
• AS-i profile S-7.3.E
• The sensors are connected via M12 connection cables
• Maximum number of modules per AS-i system: 31
• R current measurement < 50Ω
i
• Time for converting the measured values in the slave
- for one channel: 20ms
- for two channels: 120ms
- for three channels: 180ms
- for four channels: 240ms
• Sensor supply from AS-i (max. 100mA) or external 24V PELV voltage
source (black flat cable, max. 500 mA)
• Resolution: 1µA
Installation / Addressing
When you use module lower parts without addressing socket
(AC5000, AC5001 or AC5003) first address the module by placing it
onto an addressing unit (AC1144) and assign a free address between
1 and 31.
When you use module lower parts with an addressing socket (AC5010
or AC5011) the modules can be addressed with the addressing
adapter E70213 later on.
Mount the module onto the wired module lower part of the AS-i net-
work, tightening torque 0.8Nm.
As an alternative FC/FC-E lower parts with earthing lead
(AC5020...AC5023) can be used to increase the noise immunity.
