5. Auswahl & Replacement Guidelines

5.1 Core Selection Criteria

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

✅ I/O Requirement:

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

Ausgabe: Verify 2 Sicherheit + 2 auxiliary contacts meet control demands.

Kontaktkapazität: 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 Upgrade & Ersatzoptionen

Option A: Same Series Function Upgrade

More channels: 2981800 → 2981810 (2 Kanäle, 4 Sicherheitskontakte)

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

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

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

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

Vorteil: Only 17.5mm width (5mm narrower), identische Funktionen, spart Platz im Schrank.

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

Lösung: PSRmodular system + safety function modules

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