I/O Modules - Bihl+Wiedemann GmbH

Bihl+Wiedemann offers a wide variety of ASi modules, all of which are compatible with the current ASi-3 resp. ASi-5 standard. These are equipped with a various number of in- and outputs offering the right module for any application. Nor are special requirements a problem, such as sensors powered from ASi or external voltage (AUX). The large selection of analog modules reflects the commitment to offering the right module for any application or analog signal. Deserving special mention are high-resolution 16-bit analog modules or modules for especially fast transmission of the analog values.

An AS-Interface installation with IP67 digital modules from Bihl+Wiedemann having M12 plug-in connections offers many advantages: There are 2 x 2 connections for the yellow profile cable in the substructure of the module. These enable an clearly organized ASi installation where up to 4 ASi end caps and 2 passive distributors per module can be saved.

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.

Figure

Model

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)

PUR line, oil resistant. Further connection options are available on request.

Connection

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

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.

IO-Link data rate

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.

ASi Modules/IO-Link Masters: IP20, 22,5 mm

Cost efficient solution in IP20, 22,5 mm
IO-Link ports class A
IO-Link ports class B
If connected IO-Link devices with port class B (M12) require an andditional power supply, they have to be supplied directly via a separate power supply.

Figure	Model	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.
