- Provides eight normally open relay outputs arranged as four isolated pairs
- Switches documented low-current AC or DC resistive loads through Form A contacts
- Uses the 1771-WD wiring arm and requires external protection for unsuitable load transients
1771-OZL is an Allen-Bradley isolated-contact output module for low-current field circuits.
Each pair of relay points shares a common while remaining isolated from the other groups, allowing separate field circuits within the documented contact limits.
Confirm the load type, minimum current, common grouping and external suppression before transferring wiring to a replacement 1771-WD arm.
Availability, condition, price, and shipping time for 1771-OZL are confirmed during quotation.

- The module provides normally open Form A relay contacts
- Outputs are organized as four pairs with one common per pair
- Use the contacts only with the documented resistive-load application
- Keep each output within the documented continuous-current limit
- Do not connect output points in parallel
- Provide application-appropriate external circuit protection before energizing field power
- Match the original rack, group, slot, and output-image assignment
- Transfer each load and group common to the corresponding terminal
- Verify field voltage, polarity where applicable, and load type before startup
- Low-energy resistive AC/DC load switching
- Isolated annunciator and indication circuits
- Legacy 24 V on/off control with paired commons
