- 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.

- 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
