Frequently Asked Questions (FAQ)

• Q: Are the relay outputs isolated from each other?
  Yes, the TC-FOR081 provides 2550 Vdc isolation between any two sets of contacts.
• Q: What is the maximum load for AC outputs?
  This module supports 2 A resistive at both 125 Vac and 240 Vac. Inductive loads also allow 2 A steady with 15 A inrush make.
• Q: Does this module include internal fusing?
  No, the outputs are not fused. Honeywell recommends using a fused terminal base with a 3.0 A Littelfuse 239003.
• Q: Can I switch DC loads with this relay?
  Yes, it handles DC loads from 5 Vdc up to 125 Vdc with current ratings as listed per voltage.
• Q: What is the expected contact life?
  The electrical contacts last a minimum of 100,000 operations at rated loads.
