Safety I/O Modules

Bihl+Wiedemann offers the right module for accessing any safety input signal. Both control cabinet modules (IP20) and field modules (IP67) are available. From a single safety input or output to safety multi-I/O modules we offer the right AS-i slave for your requirements. Many of our modules also include available outputs for standard signals.

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.

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.
