5. Selezione & Linee guida per la sostituzione

5.1 Criteri di selezione fondamentali

✅ Safety Level Matching: Ensure required safety rating (SIL/PL/Cat.) does not exceed product capability (SIL 3 / Cat.4 PL e).

✅ I/O Requirement:

Ingresso: 1 channel sufficient; confirm NC or NO contact type.

Produzione: Verify 2 sicurezza + 2 auxiliary contacts meet control demands.

Capacità di contatto: Ensure load current ≤2.5A (AC-15/DC-13).

✅ Delay Requirement: Confirm 0.1–30s adjustable range covers equipment stopping time.

✅ Reset Mode: Select auto or manual reset according to operation needs.

✅ Environmental Adaptation: Operating temperature ≤60℃ and humidity within industrial standard range.

5.2 Aggiornamento & Opzioni di sostituzione

Option A: Same Series Function Upgrade

More channels: 2981800 → 2981810 (2 canali, 4 contatti di sicurezza)

Add alarm output: 2981800 → 2981820 (with alarm output)

Shorter delay: 2981800 → 2981801 (0.1–10 secondi) O 2981802 (0.1–1s)

Option B: Migrate from PSRclassic to PSRmini (Space Optimization)

Modello sostitutivo: 2981900 (PSRmini-SCP-24DC/ESD/4X1/30)

Vantaggio: Only 17.5mm width (5mm narrower), funzioni identiche, consente di risparmiare spazio nell'armadio.

Option C: Migrate from PSRclassic to PSRmodular (Espansione del sistema)

Soluzione: PSRmodular system + safety function modules

Vantaggio: Multi-channel expandable; integrates safety gate, E-stop, light curtain and other safety functions, suitable for complex safety systems.

5.3 Risoluzione dei problemi comuni

Contatto della Fenice 2981800 (PSR-SCP-24DC/ESD/4X1/30) is a single-channel safety relay with adjustable power-off delay, specially designed for emergency stop and safety gate monitoring, reaching the highest safety level SIL 3 / Cat.4 PL e. Its 22.5mm slim design and plug-in wiring facilitate installation and maintenance, while the 0.1–30s adjustable delay adapts to various equipment shutdown requirements.
