Technical Support
What does channel isolation provide?
1000V isolation protects each input from electrical noise and prevents ground loops in sensitive measurement applications.
How accurate is the signal conversion?
The 1771-ILK provides 15-bit plus sign resolution for highly precise analog-to-digital conversion.
What is the maximum update rate?
All 8 channels update every 500 milliseconds, providing consistent data refresh for process monitoring.
Can I mix voltage and current inputs?
The module supports both voltage and current signals but requires consistent input type configuration per application setup.
Is special wiring required?
Standard industrial wiring practices apply, using the included 1771-WF wiring arm for easy installation and maintenance.
