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
profile S-7.3 and the AS-i specification V2.1.
• Current measurement 4...20 mA (AC2616)
or voltage measurement 0...10 V (AC2617)
• AS-i profile S-7.3.D
• The sensors are connected via cage clamps
• 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
• Sensor supply from AS-i (max. 90 mA) or external 24 V PELV voltage
source (black flat cable)
• 16-bit resolution
• 50 Hz or 60 Hz filter in the A/D converter, parameter setting via the
parameter bit P0
