The Allen-Bradley 1756-IB32 is a Input Module for the ControlLogix automation platform. As a fundamental component of the 1756 I/O family, it serves as the primary interface for the controller to receive discrete 24V DC signals from field-level devices such as proximity switches, pushbuttons, and limit switches. Its high-density 32-point architecture makes it an ideal choice for large-scale industrial applications where cabinet space is at a premium and high I/O counts are required.

The 1756-IB32 input module from Allen Bradley, part of the ControlLogix family, offers robust functionality for various control applications. It supports 32 individual inputs with a configuration that allows for 16 points per group. Operating voltage spans from 10 volts to 31.2 volts DC, catering to a variety of signaling needs. This module has a current draw of 120 milliamps when receiving 5.1 volts and a mere 2 milliamps with 24 volts present.

The 1756-IB32 Allen-Bradley Input Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Power consumption is efficient, with total backplane power measured at 0.66 watts. The maximum power dissipation reaches 6.2 watts when the operating temperature is at 60 degrees Celsius, alongside a thermal dissipation rate of 21.1 BTU/hr at this temperature. The input module features enhanced performance with a maximum off-state voltage capped at 5 volts and an upper limit on off-state current of 2.27 milliamps.
 
In terms of operational thresholds, the on-state current must be at least 4.8 milliamps, achievable at 10 volts DC, while it may peak at 5.5 milliamps when 31.2 volts DC is supplied. The device can withstand a maximum inrush current of 250 milliamps without issue, allowing for flexible operation in dynamic environments. The input impedance is noted at 5.67 kΩ when running at maximum voltage. This input module is housed in an open-style enclosure, providing ease of access and installation for integration into larger control systems.

Terminal Block (RTB) Wiring: Wire the 36-pin RTB (1756-TBCH recommended) before mounting. The 1756-IB32 uses two groups, each with its own power supply.
Keying: Key the RTB to prevent incorrect module insertion (typically slot 1-3, 3-5).
Module Insertion: With the chassis powered, align the module with the top and bottom chassis guides and slide it in until it snaps.
Secure RTB: Seat the RTB firmly onto the module until the latches lock it in place.
Configuration: 1756-IB32 modules do not use DIP switches. Configuration is done via Studio 5000/RSLogix 5000, which automatically writes settings to the module.

FAQs

  • What is the voltage range?

    +
    The module has a nominal voltage of 24V DC and an operating range of 10–31.2V DC.
  • Can it be used in remote I/O?

    +
    Yes, it can be placed in a local chassis with a processor or in a remote chassis via a communication adapter.
  • What is the difference between the 1756-IB32 and 1756-IV32?

    +
    The 1756-IB32 is a sinking input module (requires sourcing sensors/devices). The 1756-IV32 is a sourcing input module (requires sinking sensors/devices)
  • How are faults diagnosed?

    +
    The 1756-IB32 has a module-fault word containing 32 bits, which corresponds to the status of each of the 32 input channels. This allows for monitoring communications faults and individual channel diagnostics.
