Features:

  • Plug-in Industrial Relay with Power Contacts
  • 4 Changeover Contacts (4 PDTs)
  • Built-in Test Button and Status LED
  • Mechanical Switch Position Indicator
The PHOENIX CONTACT REL-IR-BL/L-24DC/4×21 1032527 is an electromechanical plug-in relay with four changeover contacts. It operates from a 24 V DC coil with a nominal power consumption of approximately 1.1 W. The relay is designed for DIN rail mounting using a base element (REL-IR-BL/L base). The relay features four SPDT (single-pole double-throw) contacts constructed from AgNi (silver-nickel) material.

Each contact is rated for a maximum switching current of 8 A at 250 V AC or 250 V DC. The maximum breaking capacity is 2000 VA for AC loads and 240 W for DC loads. The relay supports AC1 resistive load switching at 8 A / 250 V AC, AC15 inductive load switching at 3 A / 250 V AC, DC1 resistive load switching at 8 A / 24 V DC, and DC13 inductive load switching at 2 A / 24 V DC.

The REL-IR-BL/L-24DC/4×21 1032527 PHOENIX CONTACT Single relay may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The mechanical service life is rated at a minimum of 20 million operations. Electrical service life under AC1 and DC1 conditions is rated at a minimum of 100,000 operations. The relay operates with a pick-up voltage of ≤ 16.8 V DC and a drop-out voltage of ≥ 2.4 V DC. Operate time is ≤ 15 ms and release time is ≤ 10 ms.
The REL-IR-BL/L-24DC/4×21 is rated for ambient temperatures from −40°C to +70°C during operation. It carries UL, cULus, CE, and VDE certifications and complies with IEC/EN 61810 and IEC/EN 60947-5-1 standards. The relay is suitable for industrial control applications requiring reliable switching of multiple circuits from a single 24 V DC control signal.
  • Machine Building: Integrates into automated machinery, packaging, and conveyors for localized logic switching
  • Control Cabinets: Used as a standardized, space-saving component for panel shop integration
  • Automotive: Deployed in production assembly networks and robotic control systems

Manual Verification: Before switching on control power, use the integrated mechanical test button on the front of the housing. Pressing this forces the contacts to change state, allowing you to trace your output wiring circuits without needing a live 24V signal.
Status Indicators: Power on the system and trigger the 24V DC control signal. Check that the yellow LED lights up and the mechanical status flag shifts position, confirming healthy coil excitation and contact movement.

Technical notes

The REL-IR-BL/L-24DC/4×21 achieves a mechanical service life of 3 × 10⁷ cycles, ensuring long-term operation with minimal maintenance. The REL-IR-BL/L-24DC/4×21 is rated for ambient temperatures from −40°C to 70°C during operation and storage/transport, with a degree of protection of RT II and ≥ IP54 at the installation location.
