SLC 500 • 16-Point Sinking DC Input
Allen-Bradley 1746-IB16 | SLC 500 16-Point DC Input Module
Application Position
The 1746-IB16 is a 16-channel 24 V DC sinking input module for SLC 500 systems, intended for conventional discrete field-device sensing.
Designed around the modular SLC 500 architecture, with the exact electrical role determined by the catalog number and installed system configuration.
CORE ENGINEERING PROFILE
Module type SLC 500 digital DC input module; current sinking
Number of inputs 16
Input signal 10…30 V DC
Input category 24 V DC class discrete input
Backplane isolation Optically coupled input circuitry with module/backplane isolation
Interface Digital
Typical application 24 V DC switches, sensors and discrete control signals
Platform Allen-Bradley SLC 500 1746 I/O family
Input polarity Sinking-input architecture
Module density 16 input points per module
For an existing SLC installation, confirm the input wiring method, sensor output type, operating voltage, chassis slot and module series before replacing the installed unit.
FAMILY / SYSTEM RELATIONSHIP
Where 1746-IB16 fits in the SLC 500 architecture
The 1746-IB16 is a standard-density sinking DC input in the 1746 family. The 1746-IB32 provides the same general sinking-input role at 32 points, while the 1746-IV16 is a sourcing-input alternative. The choice between these modules is primarily driven by field-device polarity, point count and available chassis space. Selection lens
For an existing SLC installation, confirm the input wiring method, sensor output type, operating voltage, chassis slot and module series before replacing the installed unit.

Purchase-Focused FAQ
Q1. Allen-Bradley 1746-IB16 — When is 1746-IB16 a better fit than 1746-IB32?
When the application needs 16 or fewer sinking DC inputs, the smaller point count can match the existing I/O architecture without adding unused input capacity.
Q2. Allen-Bradley 1746-IB16 — Can 1746-IB16 be used with sourcing field devices?
The 1746-IB16 is a sinking-input module. The field device and input module must have compatible current direction and common wiring; a sourcing-input application may instead require the 1746-IV16 family.
Q3. Allen-Bradley 1746-IB16 — Does 1746-IB16 cover typical 24 V DC control voltage?
Yes. Its specified input signal range is 10…30 V DC, covering the conventional 24 V DC control level while leaving the actual field-device output characteristics to be checked.
Q4. Allen-Bradley 1746-IB16 — What should be verified before replacing 1746-IB16 in a running SLC system?
Check the catalog number and series, input polarity, field voltage, terminal wiring, chassis slot and controller I/O configuration. The replacement should match the electrical role rather than only the physical appearance.
Q5. Allen-Bradley 1746-IB16 — Why does the sinking/sourcing distinction matter on 1746-IB16?
It determines how the field device and module complete the input circuit. Using the wrong polarity architecture can prevent a valid sensor signal from being recognized even when the nominal voltage looks correct.
