IFM Electronic AS-interface AC2216 Notice De Montage page 10

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 (AC2216)
or voltage measurement 0...10 V (AC2217)
• AS-i profile S-7.3.E
• The sensors are connected via Combicon connectors (accessories, e.g.
E70230)
• 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 (the external supply voltage is selected automatically as
soon as an external 24 V voltage is applied)
• Resolution: 16 bits /1 µA (AC2216) or 16 bits /1 mV (AC2217)
• Value range: 4000 ... 20000 dec. (AC2216)
or 0 ... 10000 dec. (AC2217)
Addressing
Assign a free address between 1 and 31, the address set at the facto-
ry is 0.
Address the slave with the addressing unit AC1144.
The module can be addressed when mounted and wired with the
addressing cable (E70213) via the implemented addressing interface.
Addressing via the addressing socket is only allowed when dis-
connected.
