      Information

      Overview Manuals Common Applications Product Precautions
      Allen-Bradley 1746-OB16E is an electronically protected 16-point sourcing DC output module for SLC 500 systems. It switches configured DC field loads and reports overload or short-circuit conditions through its electronic protection behavior.
      • Sixteen sourcing outputs: Controls sixteen DC load points in one common group.
      • Electronic protection: Protects the module against documented short-circuit and overload conditions.
      • Removable terminal block: Allows the field terminal assembly to be separated from the module during controlled service.
      • Series B fast-off behavior: Provides the documented fast-off feature for Series B and later hardware.

      Confirm the complete 1746-OB16E series marking, terminal assignment, supply range, point and module current limits, load suppression and SLC slot configuration before energization.

      Important Notice: Confirm the complete Allen-Bradley 1746-OB16E identity and controlled configuration before commissioning.

      The first document presents model-specific technical and system data. The second provides a separate installation, connection, commissioning and acceptance workflow.

      DC solenoid control
      Switches approved DC solenoid loads within the point and module limits.
      Indicator and relay outputs
      Drives documented DC indicators and relay coils.
      SLC 500 machine control
      Adds protected discrete outputs to a modular SLC station.
      Installed-base renewal
      Supports controlled replacement while retaining the exact terminal, slot and load records.
      Read the applicable Allen-Bradley instructions before work. Verify Allen-Bradley 1746-OB16E and the installed system configuration before commissioning.
      1
      Verify the complete 1746-OB16E marking and hardware series.
      2
      De-energize the SLC chassis and field supply before wiring work.
      3
      Confirm the 10 to 30 V DC field-supply range and polarity.
      4
      Do not exceed the point or total-module current limits.
      5
      Record the removable terminal-block and slot assignments before removal.
      6
      Review the official load-suppression guidance for every inductive device.
      7
      Do not assume the fast-off behavior of another hardware series.
      8
      Test each output, module diagnostics and the controlled machine sequence before release.
