- Basic Model Information
주문번호: 772100
모델: PNOZ X2 24VAC
공급: 24뷔와
재설정 모드: Auto-reset (no external start terminals; outputs close upon power restoration)
안전 연락처: 2 force-guided normally open contacts 13-14 / 23-24
안전 수준: 카테고리 4 / PL 전자 / SIL3
- Complete Terminal Definition (Top to Bottom)
2.1 전원 단자 (Left Supply Area)
A1: 24V AC Live (엘)
A2: 24V AC Neutral (N)
> Supply range: 20.4~26.4V AC; a 1A slow-blow fuse is recommended upstream
2.2 Safety Input Monitoring Terminals (Middle Input Circuit)
S11: Common input terminal (24V AC incoming line)
S12: 채널 1 입력 (one end of E-stop/safety gate NC contact)
S22: 채널 2 입력 (second redundant channel for dual-circuit design)
> This model has no S21 and no Y1/Y2 start terminals, purely auto-reset design
2.3 Safety Output Contacts (Right Load Circuit)
- 13-14: 1st set of force-guided safety NO contacts
- 23-24: 2nd set of force-guided safety NO contacts
No auxiliary contacts or feedback circuit terminals
- Two Standard Wiring Schemes (Field Commonly Used)
계획 1: Single-channel Wiring (Only meets PL d, for simple low-risk machines)
애플리케이션: Low-risk equipment with single E-stop only
- Connect S11 to 24V AC L
- Short-circuit S12 and S22 together
- Wire E-stop NC contacts in series to the short joint, then route back to A2 (N)
원칙: Two input lines shorted; internal single-channel monitoring only, unable to detect short circuits between contacts
계획 2: Dual-channel Redundant Wiring (Mandatory Cat.4/PL e for Machine Tools & 자동화 라인)
애플리케이션: 사출 성형, stamping, 로봇공학, production line safety gates
- S11 = 24V AC L
- S12: 1st NC contact of E-stop
- S22: 2nd NC contact of E-stop
- Parallel the other ends of both contacts and connect to A2 (N)
장점: Detects input earth short circuits, inter-cable short circuits and single contact welding
Standard Output Wiring
Wire contactor coils and main circuit control power in series with 13-14 + 23-24 in series (dual safety cut-off)
저항 부하: 230V/6A
Inductive contactor load: Install RC surge suppressor in parallel with coil
Fit a 6A fuse upstream of outputs to prevent contact welding

Indicator Status Reference Table
| 현상 | Equipment Status |
| POWER LED off | No 24VAC supply, 끊어진 퓨즈, reversed/short-circuited A1/A2 terminals |
| POWER LED on, CH1/CH2 all off | E-stop activated, safety gate open, broken input cable or input earth short |
| POWER LED on, single CH LED off | Open circuit in one dual channel, damaged contact, locked fault due to inter-cable short |
| All LEDs on, no voltage at outputs | Internal contact welding, irreversible module hardware failure |
- 문제 해결 매트릭스 (Phenomenon → Root Cause → Resolution Steps)
잘못 1: POWER LED fails to light up after power-on
- No 24VAC measured at A1-A2: Check upstream circuit breaker, fuse and transformer supply
- Normal voltage at A1/A2 but LED remains off: Internal power supply damaged; 바꾸다 772100 directly
- Terminal short circuit: Cut power, rework wiring and eliminate cable insulation earth leakage
잘못 2: 전원 공급 정상, CH LEDs off, safety outputs de-energized
- E-stop NC contact open: Reset E-stop button
- Broken input cable: Measure continuity between S11-S12/S22 section by section
- Input cable earth short: Disconnect cables and locate grounding fault segment by segment
- Single contact failure under dual-channel wiring: Replace dual-circuit E-stop switch
잘못 3: All LEDs illuminated but machine fails to start (no output at 13-14/23-24)
- Blown output circuit fuse: Replace fuse and check for shorted contactor coil
- Welded safety contacts: Irreparable module damage; install new unit
- Load current exceeding 6A: Add intermediate relay to expand output capacity
잘못 4: Random tripping and CH LED extinction during operation (간헐적인 결함)
- Excessively long cables with excessive line resistance: Use thicker cables or shorten wiring routes
- Interference from power cables routed alongside safety wiring: Separate cable runs with ≥20cm clearance
- High contact resistance caused by oxidized contacts: Replace E-stop / safety gate switch
- Strict Forbidden Operations (Violation leads to lost safety certification or burnt module)
- Never connect 220V mains to A1/A2; only 24V AC is permitted
- Never omit the second contact in dual-channel wiring (Cat.4 compliance cannot be achieved)
- Never feed an independent external power source to input circuits; input power must share the same 24VAC supply as module A1/A2
- Do not parallel output contacts for capacity expansion; series connection only. Use external safety contactors for load expansion
- Never drive high-power inductive loads without fuses; high risk of contact welding
- Do not plug/unplug input cables while the module is live; electric arcs will damage internal monitoring circuitry

- Replacement Selection Criteria (Must Verify Before Swap)
3.1 Mandatory Identical Parameters (Otherwise Direct Wiring Impossible)
- 정격 공급 전압: 772100 fixed at 24V AC. DC24V models cannot be directly replaced unless an AC/DC power converter is added.
- Reset logic: Original equipment uses auto-reset. Do not select forced manual reset models (X2.1, XPS-AC3710, 등.)
- Number of safety contacts: 2 sets of force-guided NO contacts (13-14 / 23-24). Avoid models with 3NO + 1NC 보조 접점.
3.2 Minor Compatible Differences (No Program Modification Required, Minor Wiring Adjustment Only)
- Terminal pitch / 터미널 유형: Screw vs spring terminals only require different crimping tools
- Indicator layout: No impact on safety functions
- Maximum cable length limit: Difference ≤50m among all 22.5mm compact modules, negligible for field wiring
- Modification Precautions for Replacement
- Optimal zero-modification replacement: OMRON G9SE-201 AC24. Near identical terminal definition, 치수, safety level and auto-reset logic as 772100; electricians can reuse existing wiring without changes.
- Schneider XPS-AC3110 mapping: Input terminals S11/S12/S22 correspond to XPS IN1/COM/IN2; output contact series wiring method is fully identical.
- Mixed model prohibition: Replacing auto-reset unit with manual reset model will prevent automatic machine startup after power-on; external reset button must be installed additionally.
- Safety certification retention: All listed models comply with EN ISO 13849 Cat.4 PL e and IEC 61508 SIL3. Machine overall safety certification remains valid after replacement.
- Load protection: 6A fuse must still be fitted on outputs post replacement; RC snubber circuit mandatory for inductive contactor coils.
- 빠른 선택 권장 사항
- Imported zero-wiring-modification replacement: G9SE-201 AC24 (오므론)
- Matching Schneider system equipment: XPS-AC3110
- Phoenix Contact cabinet integrated solution: PSR-SCP-24AC/ESA2/2X1
- 비용 효율적인 국내 대안: SRS2-24AC (Covestro)
- Replacement for original DC model 772101: G9SE-201 DC24 / XPS-AC5110
