FAQ

Q: Does the 05701-A-0326 provide relay outputs?
A: No, this is a sensor input-only interface card. For relay outputs, use 05701-A-0327, 05701-A-0328, 05701-A-0329, or 05701-A-0330.

Q: Is the 05701-A-0326 still in production?
A: This part is phased out but may be available via factory replacement service or authorized surplus suppliers.

Installation Guide

1. Power down the System 57 rack.
2. Insert the field interface card into the appropriate slot.
3. Connect field sensor wiring directly to the terminal block.
4. Verify proper signal continuity to the control card.
5. Power up and perform sensor calibration.

Selection Tips

• Use 05701-A-0326 when only sensor input termination is needed (no local relays).
• For alarm relay outputs, select from the 05701-A-0327 through 05701-A-0330 series.
• Verify availability as this part is phased out; consider 05701-A-0327 as an alternative.
