I/O Modules

Bihl+Wiedemann offers a wide variety of AS-i modules. 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 AS-i 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 AS-i installation where up to 4 AS-i 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 AS-i 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 (AS-i slaves) however only the one AS-i 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.

Protection rating
Inputs digital Outputs digital

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

Input voltage (sensor supply)

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

Output voltage (actuator supply)

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

AS-i connection

AB Slave (max. 62 AB Slaves/AS-i network), 2 AB Slaves (max. 31 modules with 2 AB Slaves), Single Slaves (max. 31 Single Slaves/AS-i network), mixed use allowed.
For modules with two slaves the second slave is turned off as long as the first slave is addressed to address "0".
Upon request, slaves are available with specific AS-i Slave profiles.
