The IC694MDL660-CC is the complete supplied identification for a 32-point 24 V DC input module in the IC694 I/O family used with PACSystems RX3i hardware. The module accepts positive-logic or negative-logic field input circuits and reports discrete device states to the controller.

Its selectable 0.5–100 ms ON/OFF response time lets maintenance teams match input filtering to the machine requirement. For replacement work, compare the full -CC nameplate, terminal assembly, field-supply range, circuit polarity and project settings rather than selecting by the IC694MDL660 base number alone.

Purchase verification

Send the complete -CC nameplate, terminal-block photos, existing wiring polarity and configured response time. We will check the requested unit against the installed RX3i hardware before quotation.

Send Sales Manager Myrtle the full IC694MDL660-CC label, RX3i rack and CPU information, terminal-block photos, wiring polarity, configured input-response setting, quantity and destination. We will review the stated configuration and identify any revision or field-wiring detail that still needs confirmation.

Will IC694MDL660-CC replace an installed IC694MDL660 without further checks?

Do not select by the base number alone. Compare the complete -CC nameplate, terminal assembly, rack position, field-supply range, wiring polarity and configured response time with the installed module before purchase.

Can IC694MDL660-CC be wired to both sourcing and sinking field devices?

The official product data lists positive/negative logic input capability. Confirm the actual circuit polarity, common arrangement and 20–30 V DC field supply against the project drawing before moving any conductor.

How should I choose the IC694MDL660-CC 0.5–100 ms input-response setting?

Use a shorter setting where fast state detection is necessary and a longer setting where contact chatter or electrical noise must be filtered. Record the original value and restore the project-approved setting during replacement.

What voltage must reach IC694MDL660-CC for an input to register ON?

The product data specifies an ON threshold above 11.5 V and an operating supply range of 20–30 V DC. Measure voltage at the module terminal under real load; a healthy supply measured elsewhere may still be reduced by wiring or contact resistance.

What should I inspect if IC694MDL660-CC inputs do not change after replacement?

Check the 24 V DC field supply, polarity, common wiring, terminal seating, controller diagnostics and selected response time. Compare the live channel status with the field voltage before changing the control program.

What information should I provide for an IC694MDL660-CC quotation?

Send the full front and side label, terminal-block photos, quantity, destination, RX3i CPU and rack details, wiring logic and current response-time setting. This lets the requested -CC revision be checked before stock is confirmed.
