Engineering Advantages
- Hot-swap capable within the S800 I/O station — minimizes planned downtime during module replacement
- Integrated diagnostics — per-channel fault detection with status LEDs and PROFIBUS/FOUNDATION Fieldbus-reportable alarms
- High channel density — 16 DO points in a single compact module reduces panel footprint
- Optocoupler isolation — protects controller backplane from field-side transients and ground loops
- Deterministic scan cycle — synchronized with AC800M CPU for predictable output latency in safety-critical sequences
- Wide operating temperature range — suitable for non-air-conditioned MCC rooms and outdoor enclosures
System Architecture & Signal Flow
The HENF209736R0003 P4LQA slots into an S800 I/O station connected to the AC800M CPU module via the ModuleBus (or optionally via CI830/CI840 PROFIBUS DP coupler). The CPU writes output data to the module’s internal register map each scan cycle. The module’s onboard ASIC latches the register values and drives the 16 transistor output channels accordingly. Each channel’s status (on/off, fault) is read back to the CPU for HMI display and alarm management. Field wiring connects to the module’s front-mounted terminal block, supporting both individual and common-return wiring topologies.

Technical FAQ
Q: Is HENF209736R0003 compatible with the AC800M PM860 / PM861 / PM864 CPUs?
A: Yes. The module is compatible with all AC800M CPU variants when installed in an S800 I/O station connected via ModuleBus or PROFIBUS DP coupler.
Q: Can this module be used in SIL-rated safety loops?
A: The standard HENF209736R0003 is not SIL-certified. For safety-instrumented systems, ABB’s S800 Safety I/O range (e.g., DSTD110) should be specified.
Q: What is the difference between P4LQA and other variant codes?
A: ABB variant codes encode hardware revision, firmware baseline, and regional approval markings. P4LQA denotes the specific hardware revision and approval set for this part number. Always order by full part number + variant to ensure exact replacement.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. CoC and inspection reports are available upon request for all orders.
Q: What is the minimum order quantity?
A: MOQ is 1 unit. Volume pricing is available for orders of 5+ units — contact us for a quote.
