Technical data

Type Active distributor ASi-5
Model ASi module with integrated IO-Link master
Configurable I/O‘s

Port class A: In this type, Pin 2 is assigned with an additional digital input.

Port class B: This type provides additional supply voltage and is suitable for the connection of devices that have an increased power demand. In this case, pins 2 and 5 are used to provide additional (galvanically isolated) supply voltage.

Configurability: The C/Q connections may be used for IO-Link configuration or as digital input/output signal.

1 x IO-Link Port Class A
Sensor supply (IO-Link supply and input/output supply)

IO-Link and additional inputs/outputs are supplied by ASi or by AUX (auxiliary 24 V power). If supplied by ASi, inputs can neither be connected to earth nor to external potential.

out of ASi
M8/M12 wiring

Single wiring: 1 input or output per connection.


Y wiring: 2 inputs or outputs per connection.


Mixed wiring: 1 input and 1 output per connection.


Exact pin assignment see data sheet.

IO-Link Port Class A
IO-Link data rate

COM1 = 4.8 kBaud

COM2 = 38.4 kBaud

COM3 = 230.4 kBaud (optional according to Specification V1.0)


An IO-Link device supports only one of the defined data transmission rates.

According to Specification V1.1, the IO-Link master supports all data transmission rates and adapts itself automatically to the data transmission rate supported by the device.

ASi connection

The connection to ASi as well to AUX (auxiliary 24 V power) is made via yellow resp. black ASi profile cable with piercing technology or via M12 socket (in IP20 via clamps).

Line protection: If the module is supplied via a M12 connection with A or B coding, it may only be used with a current load of max. 4 A per pin in acc. with IEC 61076-2-101 and IEC 61076-2-109. A fused tap is recommended. There is no such limitation for modules supplied via piercing contacts.

ASi profile cable
ASi address

AB address (max. 62 AB addresses/ASi network), 2 AB addresses (max. 31 modules with 2 AB addresses), Single addresses (max. 31 Single addresses/ASi network), ASi-5 address (max. 62 ASi-5 addresses/ASi network), mixed use allowed.
For ASi modules with two ASi nodes the second Asi node is turned off as long as the first Asi node is addressed to address "0".
Upon request, ASi modules are available with specific ASi node profiles.

1 ASi-5 address
