Frequently Asked Questions

• What does “individually isolated” mean?
  Each relay is completely electrically separate, allowing you to control different circuits with different voltages and grounds.
• What types of heavy loads can this module control?
  It can control motors, solenoids, contactors, heaters, and other industrial devices requiring high switching currents.
• Can I use different voltage types on the same module?
  Yes, the complete isolation allows each relay to switch different voltage types simultaneously.
• What is the advantage of high make/break ratings?
  High make/break ratings allow the relays to handle the initial surge current when switching inductive loads like motors.
• How does this module handle electrical noise?
  It features NEMA ICS 2-230 noise immunity and 1500V isolation for reliable operation in noisy environments.
