적용 가능한 시나리오: Non-high-risk equipment and ordinary domestic automated production lines
Restrictions: Not recommended for high-end export equipment, robotic systems, presses and stamping machines.
- 애플리케이션 환경 & 산업 사례
5.1 주요 응용 시나리오
This universal safety relay is used for industrial equipment requiring safe power circuit cut-off. Typical monitored components:
- Emergency stop circuit (full equipment emergency shutdown)
- Mechanical safety gates and guard switches (power cut-off once gates are opened)
- Safety light curtains and area scanners (shutdown protection when personnel enter hazardous areas)
- Two-hand control buttons (prevent misoperation on pressing and riveting machines)
- Safety limit switches and travel safety contacts
5.2 적용산업
Machine Tool Processing: 선반, 밀링 머신, 머시닝 센터, 그라인더
포장 & 기호 논리학: 포장 기계, palletizers, 컨베이어, 분류 장비
자동차 제조: 용접, assembly and coating production lines
고무 & Plastic Injection: 사출 성형기, 압출기, die-cutting equipment
일반 자동화: Robotic workstations, custom automated machinery
경공업 기계: 인쇄, textile and food processing equipment
5.3 Suitable Operating Conditions
Standard indoor control cabinets, normal temperature, dust-free or slightly dusty environments
Conventional power frequency systems (24V/110V/230V power supply)
Circuits with frequent start-stop and demand for rapid safety cut-off
5.4 Not Recommended Scenarios (지침)
- 방폭 지역: No explosion-proof certification. Use dedicated PILZ explosion-proof safety relays for explosive workshops.
- Outdoor Exposure / High Humidity & Condensation: IP40 protection is insufficient; an additional protective enclosure is required.
- Severe Electromagnetic Interference: (Near high-frequency welders or large inverters) Shielding measures and independent earthing are necessary.
- Overload Operation: Contact current must not exceed 6A. Add intermediate contactors for high-power loads.
- Ambient Temperature above 55℃: Will shorten service life of safety contacts and cause false tripping.
5.5 일반적인 적용 사례
사례 1: Safety Protection for Vertical Machining Center
구성: 772140 (24V AC/DC) + Safety gate switch + Emergency stop button
기능: Opening the equipment guard gate → Safety relay actuates → Cuts off power to spindle and feed motors; Automatic reset and restart after gate closure.
이익: Complies with machine safety standards and prevents personnel from entering mechanical hazardous zones.
사례 2: Food Flow Wrapper
구성: 772143 (230뷔와) + 안전 라이트 커튼
기능: If operators accidentally reach into the operating area → Light curtain triggers → Relay cuts off main drive power.
이익: IP40 rating adapts to slight water vapor in workshops; automatic reset ensures continuous production.
- 모델 선택 가이드
Quick Reference Rules
- The three part numbers differ only in coil voltage, with identical appearance, contacts and functions:
772140 = 24V AC/DC (만능인, first choice)
772142 = 110V AC (For Japanese-style and overseas equipment)
772143 = 230V AC (For domestic 220V mains power)
- PNOZ X2 = 2 safety NO contacts + Automatic reset
- 선택 우선순위: Confirm control cabinet supply voltage first, then verify reset mode (automatic / 수동).
- 문제 해결
| 결함 현상 | Probable Cause | 해결책 |
| Power indicator off, no response | Broken coil wiring, loose terminals, power failure | Measure input voltage, tighten screws, check upstream circuit breakers and fuses |
| 빈번한 잘못된 트립 | Loose wiring in safety circuit, electromagnetic interference, poor contact of gate switches | Re-crimp terminals, route cables away from power lines, replace worn safety switches |
| Safety circuit normal but relay fails to energize | Aged internal contacts, damaged coil, end of service life | Replace with an identical safety relay (Safety components are not repairable) |
| Output contacts cannot open (welded) | 장기 과부하, 부하 단락, frequent high-current surges | 릴레이 교체; add intermediate contactors for current division; never exceed 6A rated current |
| Abnormal reset, failed automatic restart | Incomplete closure of safety circuit, line short to ground | Check continuity of the entire safety circuit and eliminate short circuits |
Safety Regulation: Faulty safety relays are prohibited from disassembly and repair. The complete unit must be replaced.
