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 ASi slave for your requirements. Many of our modules also include available outputs for standard signals.
