Features and Benefits
24V AC Control Coil
The 24V AC coil is designed for compatible AC control circuits operating at 50/60Hz. Confirm the control supply before installation, as an AC-coil relay is not automatically interchangeable with a 24V DC version.
Two Changeover Contacts
The two changeover contacts provide separate normally open and normally closed switching paths. They support control arrangements that require two switching poles, provided the circuit and load ratings are suitable.
Test Button and Status Indicators
The red test button enables manual operation checks, while the yellow LED indicates the relay’s operating status. The mechanical indicator helps users identify the switching position during inspection.
Plug-In Industrial Design
The plug-in construction supports installation in a compatible relay socket or assembly. Verify the required accessories and terminal arrangement before ordering.
Industrial Switching Capability
The relay supports loads within the manufacturer’s specified ratings. The 12A limiting continuous current is not a universal rating for every load; motor, inductive, and other demanding loads may require different ratings and additional suppression.
Typical Applications
Depending on the electrical design, this relay may be used in:
– Industrial automation panels
– Machine control circuits
– Electrical switching systems
– Building and equipment control
– Relay interface assemblies
– Industrial monitoring and control equipment
These are typical application examples. Confirm suitability against the actual load, wiring, and safety requirements.
Compatibility and Installation Guidance
Before purchasing the Phoenix Contact 1109555 relay, confirm:
1. The control circuit supplies **24V AC**, not 24V DC.
2. The circuit requires two changeover contacts.
3. The relay is compatible with the intended socket or mounting assembly.
4. The load voltage, current, and load type comply with the manufacturer’s switching ratings.
5. The installation follows the manufacturer’s wiring and safety instructions.
The manufacturer notes that adjacent channels must not be mixed between SELV/PELV and hazardous-touch voltages, and that the outputs are not intended for switching different outer conductors. The relay must not be used as a substitute for certified safe isolation.
