Active Distributors ASi - Bihl+Wiedemann GmbH

Active distributors ASi from Bihl+Wiedemann allow you to make any sensor or actuator AS-Interface capable. Even modules without their own ASi terminal can be easily integrated into an existing ASi network using these active distributors ASi. Other features include individually configurable connection options using M8 or M12 connectors, flying leads or push-in termimals to conform to the customer’s application, as well as a compact form factor, making them ideal for use in cable ducts.

Inputs digital

Outputs digital

inputs are supplied by ASi or by AUX (auxiliary 24 V power). If supplied by ASi, inputs shall not be connected to earth or to external potential.

Input voltage (sensor supply)

Electronic outputs are supplied by ASi or by AUX (auxiliary 24 V power). If supplied by ASi, outputs shall not be connected to earth or to external potential.

For relay outputs the relay contacts are initiated from ASi. The load circuit is powered externally as specified in the data sheet.

M8/M12 wiring

Under normal conditions (no bus termination or repeater), the permissible total length of the ASi segment is max. 100 m. The calculation should take into consideration that the length of the connection cable (round cable) for each connected passive distributor must be doubled.

In the case of the active distributors (ASi modules) however only the one ASi profile cable is counted.

Round cable

Modules with a flat housing design and with cables which exit the sides make these ideal for installation in cable ducts, cable channels, cable troughs, cable rails or cable trays. Please note the respective housing depth for your particular installation.

Flat design, installation in cable duct possible

Profile cable connection

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.

Number of IO-Link Ports

Port class A (M12): Pin 4 configurable (IO-Link/DI/DO), additional digital input at pin 2. Compatible with 3 pol IO-Link devices (M8).

Configurable terminals: Terminal assignment (C/Q, L+, L-, I) compatible with pin assigment of IO-Link port class A (M12). Connected IO-Link devices with port class B (M12) with a higher current consumption have to be supplied directly via a separate power supply. Compatible with 3 pol IO-Link devices (M8).

IO-Link Port Class A

Port class B (M12): Pin 4 configurable (IO-Link/DI/DO), additional power supply (galvanically isolated) for IO-Link devices at pins 2 and 5. Compatible with 3 pol IO-Link devices (M8).

Configurable terminals: Terminal assignment (C/Q, L+, L-, I) compatible with pin assigment of IO-Link port class A (M12). Connected IO-Link devices with port class B (M12) with a higher current consumption have to be supplied directly via a separate power supply. Compatible with 3 pol IO-Link devices (M8).

IO-Link Port Class B

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.

Sensor supply (IO-Link supply and input/output supply)

Connection via M12: For IO-Link ports class B the supply of actuators is provided by an additional (galvanically isolated) power supply by AUX (auxiliary 24 V power) via Pin 2 (P24) and Pin 5 (N24).

Connection via clamps: If connected IO-Link Devices with IO-Link ports class B need a higher current consumption, additionally they can be supplied directly via the power supply.

Actuator supply (for IO-Link ports class B)
