FAQ

1. Q: Can I mix AC and DC signals on the same module?

   A: Yes, but only if you keep AC and DC signals within separate 8-point input groups due to group isolation.

2. Q: What is the advantage of dual-mode (AC/DC) inputs?

   A: It allows the module to accept both signal types, reducing the need for separate input modules.

3. Q: Are the inputs isolated?

   A: Yes, the module provides group isolation between the two 8-point input groups.

4. Q: Is this module compatible with older Series 90-30 systems?

   A: No, the IC694MDL241 is specifically designed for RX3i systems and will not function in 90-30 backplanes.

5. Q: What is the typical input current draw at 120 VAC?

   A: Approximately 8.5 mA per channel at 120 VAC.

6. Q: How are input statuses displayed?

   A: Each input has a corresponding LED indicator on the front panel.

7. Q: Is any software configuration required for this module?

   A: Yes, configuration is done via GE’s Proficy Machine Edition when defining hardware.

8. Q: Does this module support hot-swap?

   A: Yes, if the RX3i system is configured for hot-swapping.

9. Q: What happens if input voltage drops below threshold?

   A: The input will register as logic “0” (off) when below threshold levels.

10. Q: Can this module be mounted on any RX3i baseplate?

    A: Yes, it is compatible with any RX3i universal baseplate.
