Features:
- Sixteen normally open AC/DC relay outputs arranged as two groups of eight points per common.
- 5 to 265 V AC or 5 to 125 V DC operating range for qualified field loads.
- Removable terminal block for SLC 500 maintenance and replacement.
1746-OW16 converts SLC 500 output image data into sixteen electromechanical relay contact outputs. The module draws 0.170 A from the 5 V backplane and 0.180 A from the 24 V backplane; maximum resistive-load signal delay is 10 ms in each direction. Relay contact life depends on load type, switching frequency and correctly applied surge suppression.
Before replacement, save the current I/O configuration and record the slot, series, terminal-block wiring, both common circuits, load voltages and suppression devices. After installation, verify chassis diagnostics and prove every affected output under a controlled commissioning procedure.
The 1746-OW16 Allen-Bradley Relay Output Module is listed as Obsolete / Discontinued by OEM. Current revision, availability and supplied scope are confirmed in the written quotation.

1746-OW16 provides sixteen normally open relay contacts in two groups of eight points per common. Official ratings cover 5 to 265 V AC at 47 to 63 Hz and 5 to 125 V DC. Contact make/break capability varies with applied voltage and load type, so the complete relay-contact table and external surge suppression requirements must be checked before use.
Install the module in a compatible SLC 500 chassis and retain the original slot assignment unless the approved program and I/O configuration are changed. Confirm 5 V and 24 V backplane current capacity, module keying, terminal-block compatibility and processor configuration.
Record both common circuits, every output conductor, load voltage, series/revision marking and installed suppression device before removal. Inspect the removable terminal block for heat damage or looseness, then test each relay point after installation.
