نماذج الاستبدال
Direct upgrade replacement: PNOZ S2 (750102) (PNOZsigma series), وظائف متطابقة, حجم صغير, enhanced diagnostic functions
Spring-cage terminal version: No native spring-cage variant for X series; select PNOZsigma series directly.
ملاحظات تكميلية
The PNOZ X series is a legacy product and gradually phased out. The P-version supports wire short-circuit diagnosis; if two signal wires short out, ال تتابع will detect the fault and refuse to activate, greatly improving safety.

- Critical Selection Restrictions & المزالق المشتركة
- Do NOT enable short-circuit detection when using PNP OSSD safety light curtains
Light curtains already have built-in pulse diagnosis. Enabling short-circuit detection on X2P/X2.8P will cause pulse conflict and continuous fault alarms. Turn off the relay’s short-circuit monitoring in this case.
- Auxiliary NC contact (41-42) cannot be used in safety circuits
Only for PLC fault alarm and indicator feedback.
- Contact load limits
AC15 230 V max. 5 أ; DC13 24 V max. 4 أ. If contactor coil current exceeds the rating, use PZE contact expansion modules. Do not drive heavy loads directly via safety contacts.
- No time-delayed safety outputs in X series
For delayed stop applications, select PNOZ XV series instead.
- Two-hand control function
Prefer X3P or PNOZ S6; basic X models do not support two-hand logic.

- Pre-Order Selection Checklist
Confirm PL / قطة / SIL requirement: X series max. ب ل د / القطة 3 / سيل2; not applicable for PL e / القطة 4 / SIL3 applications
Input device type: E-STOP / safety gate → select P-model with short-circuit detection; PNP light curtain → disable short-circuit detection
Reset logic: Automatic start / Monitored manual start
Number of safety NO contacts required; whether semiconductor feedback to PLC is needed
جهد الإمداد; تفضيل المحطة (أفسد / spring-cage)
Load current; confirm whether PZE contact expansion modules are required
- اختيار ذاكري
أوقف & safety gate choose P-version;
Turn off short-circuit detection for light curtains;
Auto reset → X2.8P, mandatory reset → X2.7P;
X2P works for both modes; X3P provides PLC feedback;
X series only for spare parts; new projects use S-series directly.
