- 기계 & 환경 사양
설치: 기준 35 mm DIN 레일, horizontal installation
치수: 여 40 mm×H 100 mm×D 76.5 mm
작동 온도: -20 ℃ ～ +60 ℃ (inside control cabinet)
저장 / 운송 온도: -40 ℃ ～ +85 ℃
보호 등급: IP20 (for cabinet installation only)
인증: CE, UL 508, GL marine certification, EN 준수 61000 EMC industrial standards
- 내부 구조 & 터미널 정의
16 채널로 나누어져 있습니다. 4 isolated groups:
Group1: CH0～CH3
Group2: CH4～CH7
Group3: CH8～CH11
Group4: CH12～CH15
⚠️ Important Wiring Rule: The common terminal of one isolated group must share the same 24 V polarity; Do NOT connect separate, non-referenced 24 V power supplies to different isolated groups, otherwise potential difference may damage the isolation circuit.
Wiring Configurations
- Sourcing Input (PNP 감지기)
Sensor output connects to module DI terminal; module common terminals connect to 0V(접지)
- Sinking Input (NPN Sensor)
Sensor power terminal connects to 24V+, sensor output to DI terminal; module common terminals connect to +24V
- 작동 원리
External digital sensor signal → Front-end RC hardware filter circuit → Optocoupler isolation group → Signal shaping circuit → X20 bus communication chip
The controller cyclically reads channel status via X2X/X20 CPU. Filter time parameters can be configured in Automation Studio to suppress contact bounce and interference pulses generated by inverters.

✅ Direct Replacement Conditions
If X20DI9371 is used in existing projects:
Upgrade for higher anti-interference performance: X20DI9372 (pin assignment compatible, no program modification required, wiring fully interchangeable; only difference is enhanced isolation performance)
❌ Not directly interchangeable: X20DI4371 has different channel quantity and terminal layout of base unit
- 일반적인 애플리케이션 시나리오
공작기계, 포장 기계, material handling conveyors, 고무 & plastic equipment, 수처리, general automation production lines
신호 획득: Proximity switches, 광전 센서, 리미트 스위치, 푸시버튼, passive relay contacts
- 설치 지침 & 문제 해결
Strict Prohibitions
- Never apply voltage higher than 30 VDC, will permanently damage input circuits
- Do not connect two non-common-ground 24 V power supplies to different isolated groups
- Avoid parallel routing of signal cables and power cables (strong electrical interference leads to flickering signals)
일반적인 결함
- Channel LED always ON: Signal wire short-circuited to ground; abnormal power supply for PNP sensor
- Signal intermittent fluctuation: Severe electromagnetic interference → increase hardware filter time; check shielding & 접지
- All channels in one group no signal: Loss of power supply to the corresponding group common terminal
- Compatible Base Units

Wiring Specifications Recap
- PNP Sensor (Sourcing Input, Industry Standard)
All COM0/COM1/COM2/COM3 → connect to 24 VDC 0V(접지)
Sensor signal wire to DIx, sensor positive terminal to 24V+
- NPN Sensor (Sinking Input)
All COM0/COM1/COM2/COM3 → connect to +24 VDC
Sensor signal wire to DIx, sensor negative terminal to 0V
⚠️ Important: COM0/COM1/COM2/COM3 are galvanically isolated from each other.
Do not connect different COM terminals to power supplies with non-shared ground potential!
