Replacement & Compatibility FAQ
Q: Can I replace 1732ES-IB12XOBV2 with 1732ES-IB8XOBV4 without re-validation?
A: Not directly — the I/O count differs (12 DI vs 8 DI; 2 DO vs 4 DO). A safety function re-assessment is required per IEC 62061 / ISO 13849.
Q: Is this module compatible with a standard ControlLogix (non-safety) controller?
A: CIP Safety modules require a safety controller or a controller with a safety task. Standard ControlLogix without a safety task cannot consume CIP Safety data.
Q: What is the lead time for 1732ES-IB12XOBV2?
A: Typically 3–7 business days for in-stock units; 4–8 weeks for factory-new orders. Contact us for current availability.
Q: Do you supply the M12 cables and connectors separately?
A: Yes. We can supply compatible M12 D-coded and A-coded cordsets. Please specify cable length and connector gender when ordering.
Q: Can this module be used in a PROFINET safety network?
A: No. The 1732ES series is EtherNet/IP (CIP Safety) only. For PROFINET PROFIsafe, consider Phoenix Contact or Siemens ET 200 safety I/O alternatives.
