3 Functions and features
The slave receives data via the AS-Interface and converts them into analogue
output signals� The AS-i module operates as a slave with bidirectional data
transfer in the AS-i network�
The data transfer from the host to the slave is asynchronous according to the AS-i
profile S-7�3 and the AS-i specification V2�11�
• The slave can be operated in conjunction with a version 2�11 master or higher
(master profile M3 or M4)�
• Current output 0��20 mA (AC3218) or voltage output 0���10 V (AC3219)
• R
max
for current output 600 Ω (AC3218)
R
min
for voltage output > 1 kΩ (AC3219)
• AS-i profile S-7�3�6
• Maximum number of modules per AS-i system: 31
• Conversion time (digital - analogue) in the slave with four channels: < 1 ms
• Actuator supply from AS-i (max� 90mA) or external 24 V PELV voltage source
(the supply is selected automatically as soon as an external voltage is applied)
• 16 bits / 1 µA (AC3218) or 16 bits / 1 mV (AC3219)
• The actuators are connected via COMBICON terminals
4 Addressing
►
Assign a free address between 1 and 31�
The address is set to 0 at the factory�
4.1 Addressing with the AC1154 addressing unit
►
When mounted and wired the module can be addressed with the addressing
cable (E70213) via the integrated addressing interface�
No addressing via the addressing socket while live�
