The Allen‑Bradley 1756-IB16ISOE is a 16-point individually isolated 10–30V DC sequence of events (SOE) digital input module for ControlLogix PAC platform. It supports per-point timestamping with CIP Sync or CST time synchronization, FIFO event capture for first-fault and sequence-of-events logging. It is the standard non-coated version; 1756-IB16ISOEK is its conformal coated variant for harsh environments. Technical data is compiled from the product datasheet. Supplied by SHLY-PLC, an independent industrial automation distributor: every unit is visually inspected and functionally tested before shipment, in-stock ready for global shipping for machine maintenance, replacement, retrofit, and new project integration. Contact our team for compatibility verification and alternative in-stock models.

Warranty: 12-month seller warranty provided by SHLY-PLC. See our Return Policy for coverage and claims.
A: 1756-IB16ISOE is standard uncoated version. 1756-IB16ISOEK has conformal coated PCB for protection against moisture, dust and condensation; electrical and SOE functions are identical.
A: Sequence of Events (SOE) function captures precise timestamp for every input state change, used for first fault identification and event sequence analysis in critical systems.
A: Yes, it fits ControlLogix chassis and 1756 series PAC CPUs. Share your existing chassis and CPU model and our technical team will verify compatibility and provide cross-references to comparable in-stock models.
