FAQ

1. What type of I/O does the IC694MDR390 provide?
   It offers a combination of 8 DC input channels and 8 relay output channels, allowing for flexible signal handling in mixed-control applications.

2. Are the inputs optically isolated from the outputs?
   Yes, the inputs and outputs are individually optically isolated to prevent cross-interference and ensure electrical safety.

3. What is the maximum switching voltage supported by the relay outputs?
   Each relay output can handle up to 250 VAC or 30 VDC, making it suitable for both AC and DC load control.

4. Can the module handle inductive loads such as solenoid valves?
   Yes, the relay outputs are designed with surge suppression to safely switch inductive loads like solenoids and contactors.

5. How is the module powered?
   The IC694MDR390 draws power directly from the 5 VDC backplane supply of the RX3i system.

6. What kind of diagnostic information is available?
   The module includes LED indicators for each input and output channel, enabling quick visual diagnostics and system verification.

7. Is the module hot-swappable within the RX3i system?
   No, since it contains mechanical relays, the module should only be inserted or removed when power is off to avoid electrical arcing.
