Allen Bradley 1492‑REC20 IEC Duplex Receptacle

Allen‑Bradley 1492‑REC20 IEC Duplex Receptacle

The Allen‑Bradley 1492‑REC20, also cataloged as the 1492‑REC20 receptacle module, operates as a dedicated DIN‑rail mounted AC outlet assembly for supplying 125 VAC utility power to panel‑mounted industrial devices within control cabinet environments.

Hardware Specifications

Backplane Bus and I/O Density Considerations

Within Allen‑Bradley control architectures, the 1492‑REC20 provides auxiliary AC power without interacting with backplane bus communication. Its DIN‑rail form factor supports cabinet I/O density scaling by allowing utility receptacles to be mounted adjacent to PLC and I/O modules without consuming backplane slots. The thermoplastic UL 94‑V0 housing minimizes thermal load and avoids interference with firmware‑driven modules installed nearby.

Frequently Asked Questions

Q: Can the 1492‑REC20 be mounted while the cabinet is energized? A: Mechanical mounting is possible, but wiring must be performed with the circuit de‑energized to avoid exposure to live 125 VAC conductors.

Q: Does the receptacle affect PLC backplane loading? A: No. The module is passive and does not interface with the backplane or draw current from PLC power supplies.

Q: Are firmware updates or configuration required? A: No. The receptacle is a passive AC outlet with no firmware or logical configuration.

Field Installation Guidelines

• Ensure DIN‑rail engagement is fully seated before wiring.
• Maintain correct torque on terminal screws to prevent conductor loosening under vibration.
• Route AC wiring separately from low‑voltage control wiring to reduce induced noise.
• Use copper conductors only within the specified 20–10 AWG range.
• Verify enclosure spacing to avoid mechanical stress on the duplex housing.
