BWR4771ASi-5 PCB Module with integrated IO-Link Master, 65 mm x 40 mm, 4 x IO-Link ports, wiring pins, straight

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 conectors: 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).

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 conectors: 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).

In addition to connecting IO-Link devices (Class A and/or Class B) to the ASi modules with integrated IO-Link masters, it is possible to process additional digital and/or analog I/O signals, depending on the design and configuration.

C/Q (configurable IO-Link ports): The C/Q connections (pin 4) of the IO-Link masters Class A and Class B can optionally be configured for IO-Link communication, as digital inputs or as digital outputs.

I/O (self-configuring digital inputs/outputs): The I/O connections (pin 2) of the IO-Link masters Class A are self-configuring connections that can optionally be used as additional digital inputs and/or digital outputs.

I (digital inputs): The I connections (pin 2) of the IO-Link masters Class A can be used as additional digital inputs.

AI (analog inputs): The I Sig+/24V connections of the IO-Link master Class A can be used as additional analog inputs (e.g. 4 ... 20 mA).

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.

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.

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.

The connection to ASi and AUX (24 V auxiliary power) is made for modules in the active distributor or blue IP67 housing via the yellow or black ASi profile cable with piercing technology or via an M12 plug. Modules for the control cabinet are connected via terminals and PCB modules via wiring pins, connection wires or terminals.

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.

Bihl+Wiedemann offers modules with AB address, single address or ASi-5 address. In some cases, ASi modules can occupy several (different) addresses. Mixed operation of modules with different addressing in the same ASi circuit is permitted.
For ASi modules with two ASi-3 nodes, the second ASi-3 node is turned off as long as the first ASi-3 node is addressed to address "0".
Upon request, ASi modules are available with specific ASi node profiles.
