Product Description
The Allen-Bradley 1746-IB32 is a 32-channel, 24VDC discrete input module for SLC 500 systems, designed to interface with switches, sensors, and other ON/OFF devices. It operates within a 15-30V DC range at 50C (122F) or 15-26.4V DC at 60C (140F). Compatible with any SLC 500 processor and ideally suited for modular hardware, it can be installed locally, in an expansion I/O rack, or in a remote I/O chassis, occupying any available chassis slot except slot 1. It draws 50 mA at 5VDC from the backplane, features a removable terminal block for easy wiring and maintenance, and provides 1500 VAC isolation between the backplane and I/O. Key specifications include a maximum off-state input voltage of 5VDC, a nominal input current of 5.1 mA at 24V DC, typical signal delays of 8 ms, and an operating temperature range of 0-60C (32-140F). Power must be removed during installation as it does not support RIUP.
Is Your Device Showing These Signs?
The Allen Bradley 1746-IB32 DC Input Module commonly experiences failures due to blown input fuses from overcurrent events, degraded optocouplers causing unresponsive inputs, and corrosion on terminal blocks resulting in intermittent connectivity. Resolve these issues by replacing blown fuses with the correct amperage rating, swapping out faulty optocouplers on the input channels, and thoroughly cleaning or replacing corroded terminal blocks to ensure proper electrical contact and restore reliable digital input signal processing. Address grounding issues and verify proper voltage levels to prevent future damage.
