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...20 mA (AC2516, AC2566)
or voltage measurement 0...10 V (AC2517)
• 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 voltage measurement > 100 kΩ; R
i
• Time for converting the measured values in the slave
- for one channel: 20 ms
- for two channels: 120 ms
- for three channels: 180 ms
- for four channels: 240 ms
• Sensor supply from AS-i (max. 100 mA) or external 24 V PELV volt-
age source (black flat cable, max. 500 mA)
• Resolution: 1 µA (AC2516, AC2566) or 1 mV (AC2517)
• special features AC2566: stainless steel screws, Viton sealing
Installation / Addressing
When you use module lower parts without addressing socket (AC5000
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 0.8 Nm.
As an alternative FC/FC-E lower parts with earthing lead
(AC5020...AC5023) can be used to increase the noise immunity.
