Omron CJ1W-ID212 CJ Series 16‑Point High‑Speed DC Input Unit 24V Screw Terminal

Omron CJ1W‑ID212 is a 16‑point high‑speed DC input unit for SYSMAC CJ‑series PLC systems. Accepts 24 V DC signals from field devices with configurable polarity (PNP/NPN) without hardware changes. Removable screw terminal block, DIN rail mounting.

Applications:

• High‑speed digital signal acquisition for machine automation and positioning

• Conveyor and material handling system input expansion

• Packaging machinery and assembly line monitoring

• General factory automation requiring fast input response

Technical Specifications:

Core Specifications

• Number of inputs: 16 (16 points/common, 1 circuit)

• Rated input voltage: 24 V DC

• Permissible input voltage range: 20.4 V … 26.4 V DC

• Input impedance: 3.3 kΩ

• Typical input current: 7 mA (at 24 V DC)

• ON voltage/current: ≥ 14.4 V DC / ≥ 3 mA

• OFF voltage/current: ≤ 5 V DC / ≤ 1 mA

Performance Specifications

• ON response time (standard): ≤ 8.0 ms (configurable 0 … 32 ms in Unit Information settings)

• OFF response time (standard): ≤ 8.0 ms (configurable 0 … 32 ms)

• Minimal ON/OFF response time: 15 μs ON / 90 μs OFF (internal element delay, when set to 0 ms)

• Digital filter: configurable 0 … 32 ms

• Simultaneously ON points: 100% at 24 V DC (16 points at 45 °C, 12 points at 55 °C)

• Word allocation: 1 word

Electrical & Environmental Specifications

• Internal current consumption (5 V DC): 130 mA max.

• Insulation resistance: 20 MΩ min. between external terminals and GR terminal (100 V DC)

• Dielectric strength: 1,000 V AC between external terminals and GR terminal for 1 min (leakage current ≤ 10 mA)

• Protection rating: IP20

• Dimensions (W × H × D): 31 mm × 90 mm × 89 mm

• Weight: 110 g max.

• Operating temperature: 0 °C … 55 °C

• Storage temperature: –20 °C … +75 °C

• Certifications: N, L, CE

System Integration:

• This input unit belongs to the Omron SYSMAC CJ series.

• Compatible with CJ1, CJ2, CS1, NJ series CPU units and CP1H systems.

• Installs on CPU Rack or Expansion Rack via CJ I/O Bus.

• Input power polarity can be connected in either direction.

• To achieve minimal ON/OFF response times (15 μs / 90 μs), set the response time to 0 ms in Unit Information settings – internal element delays provide the true high‑speed response.
