Features:
- Provides 32 sourcing digital inputs in two 16-point groups for compact ControlLogix signal acquisition.
- Supports configurable update timing, change of state operation, and input time stamping for flexible event monitoring.
- Offers group-to-group isolation, electronic keying, and compatibility with 1756-TBCH and 1756-TBS6H terminal blocks.
Allen-Bradley 1756-IV32 gives ControlLogix users a practical way to collect a large number of DC discrete signals without spreading inputs across several modules. With 32 points available in one module, equipment builders and plant engineers can simplify rack organization while maintaining clear separation between two 16-point groups. The 10 to 30 V DC operating range matches common industrial control voltage levels. Such capability is useful in machinery, process systems, material handling equipment, and other installations that depend on frequent status feedback from field devices.
Fast and configurable signal handling gives the module flexibility across different control tasks. Cyclic input updates can be set from 200 microseconds to 750 milliseconds, while software-configurable change of state operation allows the system to react to important input transitions without relying only on periodic updates. Time stamping with plus or minus 200 microsecond accuracy also provides useful event timing data. In applications involving sequencing, machine status, alarms, or coordinated process steps, these functions can improve visibility into when field conditions change.
Allen-Bradley 1756-IV32 is also built around the electrical and environmental requirements of ControlLogix installations. Backplane consumption remains low at 0.66 W, while maximum module power dissipation reaches 4.1 W at 60 degrees C. The specified operating temperature range of 0 to 60 degrees C, storage range of minus 40 to plus 85 degrees C, noncondensing humidity range of 5 to 95 percent, and 2 g vibration rating support dependable use in industrial control cabinets. Compatibility with removable terminal blocks and software-configurable electronic keying further supports installation, replacement, and maintenance throughout the system lifecycle.
The 1756-IV32 Allen-Bradley ControlLogix 32 Pt 12/24VDC D/I Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Discrete Assembly: Suitable for centralized signal acquisition of massive proximity switches, photoelectric sensors, and limit switches in automotive manufacturing and electronic assembly lines.
- Logic Interlocking: Used for centralized management of hardware safety chain feedback, control cabinet buttons, and multi-position status monitoring in large and complex control systems.
- High-Density Deployment: In field applications with limited control cabinet space, its high-density architecture with 32 points per module significantly reduces the occupancy of local or remote I/O slots.
- Warehousing and Logistics: Suitable for real-time allocation and monitoring of high-frequency, high-concurrency signals from multiple sensors in large-scale sorting conveyor belts and automated intelligent warehouses.
- Input Type: The channels adopt a source input design; external devices need to provide sinking control signals.
- Filtering Configuration: The hardware debounce time for each input channel can be independently adjusted via software between 0 and 30 milliseconds.
- Change Detection: Supports COS (Change of State) triggering, allowing the channel to instantly activate a backplane interrupt upon detecting a signal transition.
- Diagnostic Latching: Provides input state latching logic to ensure accurate capture of short pulse edge signals even with long PLC scan cycles.
- Version Update: The hardware supports online firmware updates via ControlFlash software to obtain the latest stable control logic and system patches.
- Compatibility Cycle: The firmware supports low-level data mapping with different versions of RSLogix 5000 or Studio 5000 programming environments.
- Status Self-Check: The module firmware has a built-in low-level power-on self-test (POST) program that can automatically identify backplane communication anomalies and lock the fault status.
- Communication Synchronization: The internal firmware supports microsecond-level high-precision clock synchronization (CIP Sync) for multi-channel data acquisition via the ControlLogix backplane.
