Frequently Asked Questions (FAQ)

What type of input signals does the IC694MDL660-EC support?
It supports 24 VDC discrete input signals with both positive and negative logic configurations.

Can this module be used with Series 90-30 PLCs?
No, it is only compatible with RX3i PACSystems and requires CPU firmware version 2.90 or higher.

How many input channels does the module provide?
The module provides 32 discrete inputs, divided into four groups of 8 channels, each group electrically isolated.

Does the IC694MDL660-EC provide any built-in diagnostic functions?
Yes, it detects the presence of the terminal block and reports this status to the RX3i CPU.

What happens if the firmware of the module becomes corrupted or is missing?
All LEDs will be off, and while the CPU may still scan the module, it may not generate a fault. It’s recommended not to rely solely on diagnostic messages.

What is the significance of the TB LED color on the module?
The TB LED is green when the terminal block is properly locked in place and red when it is not secured.

What kind of isolation does this module offer?
It offers optical isolation between the field and backplane (250 VAC continuous), and between input groups (250 VAC continuous), withstanding up to 1500 VAC for one minute.
