Application-Specific FAQ
- Q: Can the IC694MDL940F switch 240 V AC motor starters directly?
- A: Yes. Each output point is rated for up to 240 V AC at 2 A continuous. For motor starters with high inrush, verify the locked-rotor current does not exceed the relay’s make rating (typically 10× rated current for ≤ 20 ms). Use an interposing contactor for loads above 2 A.
- Q: Can I mix AC and DC loads on the same module?
- A: Yes — the four isolated output groups (4 points each) allow different voltage sources per group. For example, Group 1 can switch 120 V AC solenoids while Group 2 switches 24 V DC indicators.
- Q: Is this module compatible with PACSystems RX3i racks?
- A: The IC694MDL940F is a Series 90-30 module. It is not natively compatible with RX3i racks. An IC694ACC300 Series 90-30 expansion adapter is required to use it in an RX3i system.
- Q: What is the expected relay contact life?
- A: GE specifies ≥ 100,000 mechanical operations and ≥ 30,000 electrical operations at rated load. Actual life depends on load type, switching frequency, and whether arc suppression is used.
- Q: Do you provide a warranty?
- A: Konmask provides a 90-day functional warranty on all tested units. Extended warranty options are available — contact us for details.
