More Information

Overview Manuals Logic Polarity Supply Quality Signal Integrity Application
  • Sixteen low-true TTL sinking outputs on a common 5 V reference
  • Fast switching for compatible low-current logic inputs
  • Published ripple and current limits for the external TTL supply

1746-OG16 is an Allen-Bradley sixteen-point ttl sinking output module for SLC 500 chassis.

The module interfaces SLC 500 output data with compatible 5 V logic by pulling selected signals low against the external TTL common.

Before installation or replacement, verify supply regulation, ripple, common grounding, low-true program logic, receiving-input thresholds, wiring length, and noise separation.

Availability, condition, price, and shipping time for 1746-OG16 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Treat the sinking low state as the active or true output condition
  • Use NOT logic only when required by the application’s signal convention
  • Document receiving-device polarity so maintenance does not reverse the control meaning
  • Provide a regulated 4.5–5.5 V DC field supply
  • Keep ripple at or below the published 50 mV peak-to-peak limit
  • Use a low-impedance common and verify voltage at the load under switching conditions
  • Separate TTL wiring from motor, contactor, and variable-frequency drive conductors
  • Keep cable length and capacitance compatible with the required response time
  • Confirm pull-up, leakage, and threshold behavior at every receiving device
  • Low-true TTL command signals for compatible industrial interfaces
  • SLC 500 connection to 5 V logic equipment through sinking outputs
  • Fast, low-current discrete signaling inside controlled industrial panels

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.
Why does 1746-OG16 appear to invert the program command?
The TTL outputs are low-true: an active output sinks the signal low. Use the program logic and documentation convention intended for this module.
Can 1746-OG16 drive a 24 V DC relay coil?
No. It is a 5 V TTL interface with milliampere-level output capability; use a compatible interface or a different output module for 24 V loads.
What power-quality issue commonly disrupts 1746-OG16?
Excessive ripple, voltage drop, or a poor common on the external 5 V supply can shift TTL thresholds and create intermittent logic operation.
Why might a connected logic input stay active when 1746-OG16 is off?
Check the receiving device’s pull-up network, shared common, leakage sensitivity, cable coupling, and whether the logic convention is being interpreted correctly.
Can 1746-OG16 share a common with unrelated equipment?
Only when the grounding arrangement and common reference meet both devices’ requirements. Avoid ground loops and keep the TTL return low impedance.
What should be checked before substituting another TTL module for 1746-OG16?
Compare low-true behavior, voltage tolerance, source or sink direction, point current, common arrangement, response time, connector, and the controller output image.
How should long cable runs from 1746-OG16 be handled?
Keep TTL wiring short and separated from noise sources. Verify voltage at the receiving input, common integrity, shielding practice, and the official capacitance or timing limits.
