FX2N-48ER is an I/O expansion unit for Mitsubishi MELSEC-F series FX2N PLCs.
It features 24-point DC24V input + 24-point relay output, with built-in power supply, and can directly expand I/O points for small and medium-sized automation control systems.
- 모델 분석 & Definition
| 암호 | 의미 | 설명 |
| FX2N | 시리즈 | Mitsubishi high-performance compact PLC series, supporting rich expansion and network communication |
| 48 | Total I/O points | 24 inputs + 24 outputs, total 48 mixed I/O |
| 이자형 | Expansion type | Must be used with a main unit; built-in power supply for field devices |
| 아르 자형 | 출력 유형 | Relay output, suitable for AC/DC loads with strong load capacity |
- 주요 사양
입력: 24 points DC24V, sink/source common, response time approx. 10ms
산출: 24 points relay, 2A/AC250V or 2A/DC30V per point; max 8A per common terminal
힘: AC100–240V wide range, 50/60헤르츠; 460mA DC24V for field devices
물리적: Weight approx. 0.85kg; Dimensions 182×90×87 mm (폭×높이×깊이), DIN rail mountable

- Common Versions
| 접미사 | Region | 차이점 |
| -ES/UL | Europe / 북아메리카 | CE/UL certified, DC24V input, 나사 터미널 |
| -UA1/UL | 북아메리카 | Supports AC110V input, UL/CUL certified |
| -DS | Europe | DC24V power, 나사 터미널, CE compliant |
- 장점 & 응용
장점: Built-in power supply, simple wiring; relay output can directly drive contactors, solenoids, 등. Low cost, 높은 신뢰성.
응용: Small production lines, equipment automation, building control, 포장 기계, 식품 가공, 등.
- 선택 & 사용법 참고 사항
- Used with FX2N main units (예를 들어, FX2N-64MR). Installation order: main unit → expansion unit → special function module.
- Relay response approx. 10ms, not suitable for high-speed switching. For high-speed use, select transistor output (예를 들어, FX2N-48ET).
- 나사 터미널; observe polarity of input/output common terminals to avoid short circuits.
주요 차이점: FX2N-48ER vs FX2N-64ER
Main difference: Total I/O points (48 vs 64), corresponding to 24-in 24-out vs 32-in 32-out. 치수, weight, and DC24V auxiliary power also differ; other features are identical.

- Application Impact
- Control Scale
FX2N-48ER: Small/medium machines, 포장, single-line automation
FX2N-64ER: Medium/large systems, multi-line control, more sensors/actuators
- 설치공간
FX2N-64ER is wider; extra space required in control panel.
- Field Device Power
FX2N-64ER provides more DC24V current for more sensors.
- 확장
Both support up to 7 expansion units, 최대 256 입출력.
- 선택 권장 사항
- Choose based on actual I/O; slight redundancy is acceptable.
- Space-limited panels: prefer FX2N-48ER.
- Many DC24V sensors: prefer FX2N-64ER.
- 비용: FX2N-64ER is slightly more expensive.
