5. Funcții & Scenarii de aplicare

5.1 Funcții de bază

1. Dual-channel Redundant Monitoring: Dual-channel input circuit design, safely cutting off output upon fault.
2. Inter-contact Short-circuit Detection: Optional function to prevent safety failure caused by contact adhesion.
3. Forced Guided Contacts: Safety output contacts adopt forced guided structure to ensure reliable disconnection.
4. Self-diagnosis Function: Real-time internal circuit monitoring; cut off output and indicate fault immediately when abnormal.
5. Flexible Reset Mode: Support automatic reset (power-on reset) si resetare manuala (rising-edge trigger).

7. Ghid de selecție & Soluții alternative

7.1 Selection Mnemonic Rule

Voltage Matching → Contact Quantity → Safety Level → Input Type → Reset Mode → Space Limitation

7.2 Selection Decision Tree

1. Tensiune de alimentare: Confirm system is 24VDC (750104) or 48–240V AC/DC (750134 / 751134).
2. Output Requirement: 3NO+1NC+1SO meets most scenarios; choose PNOZ s5 (4NU+1NC) for more contacts.
3. Nivel de siguranță: PL e/Cat.4/SIL 3 is mandatory for high-risk scenarios such as heavy machinery and robotics.
4. Tip de intrare: Select IN2- mode if short-circuit detection is required; IN2+ if not needed.
5. Modul de resetare: Automatic reset for unattended occasions; manual reset for manned operation areas.

7.3 Soluții alternative recomandate

1. Buget limitat: Choose Weidmüller SRB series (rentabil) or domestic Chint NJB1 series (basic safety level).
2. Integrarea sistemului: Siemens 3RK3 series (seamless connection with S7 PLC) or Schneider XPS series (compatible with Modicon PLC).
3. Extinderea funcției: Match with PNOZ s pIE / nIE pulse extension modules to realize complex safety logic.
4. Space Limited: Keep PNOZ s4 (22.5mm narrow design), avoid wide-body models.
5. Air Freight Compliance & Certificare

Certificare CE: Compliant with EN ISO 13849-1, IEC 61508, IEC 62061.

Air Freight Judgment: No built-in lithium battery / supercapacitor; belongs to ordinary industrial electronic equipment, no special air freight restrictions.

Packaging Requirement: Anti-static packaging; transport temperature: -40℃ ~ +85℃.
