        More Information

        Overview Manuals Output Groups Load Planning Fault Recovery Application
        • 32 electronically fused sinking outputs in two 16-point groups
        • 10 to 30 VDC operating range for 12/24 VDC sinking loads
        • Compatible RTBs: 1756-TBCH or 1756-TBS6H

        The 1756-OV32E provides high-density sinking DC output control for a ControlLogix chassis through two separately supplied 16-point groups.

        Load planning must follow the published point, group and module current limits, including the reduced ratings specified for operation at 60°C.

        Before commissioning, verify field polarity, both group supplies and returns, RTB keying, output states and the cause of any electronic-fuse indication.

        Availability, condition, price, and shipping time for 1756-OV32E are confirmed during quotation.

        • Map sixteen points to each independently supplied output group
        • Keep group returns and DC supplies aligned with the RTB wiring diagram
        • Treat electronic fusing as group protection rather than per-point isolation
        • Check steady current, inrush and the temperature-dependent group limit
        • Maintain the documented minimum load current for reliable state indication
        • Use external suppression when the connected inductive load requires it
        • Identify the affected fused group before replacing field hardware
        • Remove shorts and overloads before resetting or re-enabling outputs
        • Verify program-mode and fault-mode states before returning the machine to service
        • ControlLogix 24 VDC solenoid and interposing-relay control
        • High-density machine output banks with group electronic protection
        • Distributed actuator control where sinking outputs match the field wiring
        Description
        Allen-Bradley 1756-OV32E is a 32-point ControlLogix sinking DC output module with two electronically fused groups for 10 to 30 VDC loads.

        Selection and replacement must follow the exact 1756-OV32E official data, wiring and accessory requirements.

        Before commissioning, verify identity, installation, configuration, protection behavior and the connected field circuit.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Can Allen-Bradley 1756-OV32E replace a sourcing output module without rewiring?
        No. It is a sinking-output module; field polarity, commons and load wiring must match the 1756-OV32E circuit.
        Which removable terminal block should be ordered for Allen-Bradley 1756-OV32E?
        Use 1756-TBCH or 1756-TBS6H and verify that the existing keyed RTB, conductor size and terminal map match the project.
        Can all 32 Allen-Bradley 1756-OV32E outputs carry 0.5 A at 60°C?
        No. The official limits derate at 60°C to 0.35 A per point, 5 A per group and 10 A per module.
        Why can one output group on Allen-Bradley 1756-OV32E turn off while the other group remains healthy?
        Each 16-point group has separate electronic protection and field-power wiring; inspect the affected group for a short, overload, missing supply or return fault.
        What must be preserved before replacing Allen-Bradley 1756-OV32E?
        Record the slot, Series and firmware context, RTB keying, point map, both group supplies and returns, fault/program states, forcing and connected-load data.
        Why can an Allen-Bradley 1756-OV32E point appear off while a load still sees voltage?
        Check off-state leakage, field wiring, external suppression devices, return references and whether another circuit is backfeeding the load.
        How should Allen-Bradley 1756-OV32E be tested after installation?
        Command points one at a time, verify loaded voltage and current, exercise both fused groups, prove safe fault/program states and then run a controlled machine cycle.
