Technical Frequently Asked Questions

• What is dual-channel equivalent mode in safety applications?
• Configure single-channel operation first, then the module evaluates analog input pairs as safety-rated pairs.
• How many different sensor types can I connect simultaneously?
• The module supports up to four voltage, current, or tachometer sensors in any combination across its channels.
• What are the code range differences between bipolar and unipolar modes?
• Bipolar mode uses -32768 to 32767 range while unipolar mode uses 0 to 32767 for positive-only signals.
• What happens when signals exceed the configured thresholds?
• The module detects over-range and under-range conditions and can trigger safety responses based on your configuration.
• Can I use different input types on each channel?
• Yes, each of the four channels independently configures for voltage, current, or tachometer input types.
