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 0 ... 20 mA
• AS-i profile S-7.3.6
• The sensors are connected via M12 connection cables
• Maximum number of modules per AS-i system: 31
for current output 600 Ω
• R
max
• Time for converting the measured values in the slave: < 1 ms
• Actuator supply from external 24 V PELV voltage source (black flat
cable, max. 1.1 A in total)
• Resolution: 1 µA
Installation / Addressing
When you use module lower parts without addressing socket
(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
(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 0.8 Nm.
