current measurement < 50 Ω (AC3216)

Ri voltage measurement > 100 kΩ (AC3217)

• AS-i profile S-7�3�E

• Maximum number of modules per AS-i system: 31

• Conversion time (digital - analogue) 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 voltage source (the external supply voltage is selected automatically as soon as an external

24 V voltage is applied)

• Resolution: 16 bits / 1 µA (AC3216) or 16 bits/1 mV (AC3217)

• Value range: 4000...20000 dec. (AC3216) or 0...10000 dec. (AC3217)

• The sensors 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�

5 Installation

5.1 Installation of the device

► Install the device on a 35 mm DIN rail�

► Leave enough space between the unit and the top and bottom of the control

cabinet to enable air circulation and to avoid excessive heating�

► Take into account the internal heating of all devices when mounting several

devices side by side and observe the environmental conditions for every device�

5.2 Removal of the device

6 Electrical connection

The unit must be connected by a qualified electrician� The national and international regulations for the installation of electrical

equipment must be adhered to�

8.3 Transmission time of the analogue values

The transmission time of the analogue values depends on the conversion time of the analogue signals into digital signals in the AS-i module and on the transmission time via the AS-Interface�

The conversion time per analogue input signal is 60 ms� But if only channel 1 is used, i�e� all other channels are deactivated via the parameter bits P1 and P2, the conversion time for this channel is only 20 ms�

The transmission time of the 4 16-bit values via the AS-interface ideally is 7 AS-i cycles per value� For a cycle time of 5 ms per AS-i cycle this results in a transmission time of 4 x 7 x 5 ms = 140 ms via the AS-Interface�

If the channels 2 to 4 are deactivated, the transmission via the AS-Interface for one channel requires 7 AS-i cycles� For a cycle time of 5 ms per AS-i cycle this results in a transmission time of 1 x 7 x 5 ms = 35 ms via the AS-Interface�

Thus the total transmission time for 4 analogue values ideally is 240 ms

(conversion time) + 140 ms (transmission time) = 380 ms. If channels 2 to 4 are

deactivated, the transmission time ideally is 20 ms + 35 ms = 55 ms�
