Features:
- Sixteen sourcing outputs: switches positive DC power to compatible loads
- 10–50 V DC field range: covers documented industrial output circuits
- External protection required: the standard module has no electronic short-circuit protection
1746-OB16 groups sixteen solid-state sourcing outputs in a modular SLC 500 format.
Its useful load capacity depends on point current, module total, ambient temperature, and external protection.
The distinction from electronically protected catalog variants must remain visible during selection and replacement.

- Load polarity: confirm each field device is compatible with a sourcing PLC output
- Current schedule: total point and module loads at the real ambient temperature
- Minimum current: verify small indicator or relay loads meet the documented threshold
- External device: provide coordinated overcurrent protection outside the module
- Inductive energy: apply suppression to solenoids, relays, and contactors as documented
- Failure containment: separate vulnerable branches where one short must not disable unrelated loads
- Safe-state test: observe loads during controller and field-power removal
- Point proof: command each output and measure the intended device response
- Thermal observation: check the module under the actual simultaneous-load pattern
- DC solenoid control: switch compatible valves with external suppression
- Relay and contactor drive: energize documented coils within current limits
- Panel signaling: operate DC indicators that meet the minimum load requirement
