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

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

5.2 Atualizar & Opções de substituição

Option A: Same Series Function Upgrade

More channels: 2981800 → 2981810 (2 canais, 4 safety contacts)

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

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

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

Modelo de substituição: 2981900 (PSRmini-SCP-24DC/ESD/4X1/30)

Vantagem: Only 17.5mm width (5mm narrower), identical functions, economiza espaço no armário.

Option C: Migrate from PSRclassic to PSRmodular (System Expansion)

Solução: PSRmodular system + safety function modules

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

5.3 Solução de problemas comuns

Contato Fênix 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.
