Features:
- Switches four independent changeover paths from one 24 V DC coil.
- Combines a test button, yellow LED, and mechanical contact-position indication.
- Plugs into a compatible Phoenix Contact relay base for external circuit termination.
Phoenix Contact REL-IR-BL/L-24DC/4X21 1032527 keeps the removable relay mechanism separate from the base that carries the cabinet wiring.
The LED follows coil energization while the mechanical indicator follows the physical switching mechanism, giving two different state references.
Contact ratings, insulation limits, and the selected base determine which four circuits may be switched together in the installed arrangement.
The Phoenix Contact REL-IR-BL/L-24DC/4X21 1032527 Plug-In Industrial Relay may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Input energization and timing
- Nominal input: The polarized coil is rated for 24 V DC.
- Operating span: The documented input range is 19.2 to 46.8 V DC at 20 °C.
- Pickup: The relay typically responds in 15 ms.
- Release: The contact mechanism typically returns in 10 ms.
Four AgNi changeover circuits
- Arrangement: Four single changeover contacts switch from one coil mechanism.
- Continuous path: Each documented path is limited to 6 A continuous current.
- Voltage boundary: The maximum switching voltage is 250 V AC or DC.
- Inrush boundary: Normally open contacts can accept 12 A for 20 ms.
Electrical and mechanical indication
- Yellow LED: A bidirectional LED indicates that coil voltage is present.
- Position flag: The mechanical window follows the actual contact mechanism.
- Test button: The front control can move the mechanism during commissioning.
- Separate evidence: The LED and position flag should be read together when checking coil and contact state.
Plug-in mounting boundaries
- Required base: The relay needs a compatible Phoenix Contact base for wiring and operation.
- Zero spacing: Relay bodies may be placed in rows without a gap.
- Enclosure: The installation location must provide at least IP54 protection.
- Circuit separation: Adjacent contacts must not mix SELV/PELV with hazardous-touch voltages because safe isolation is not guaranteed.
