Omron SYSMAC CJ-series Digital Output Unit

Description

• CJ1W-OD213​ → 16 outputs (occupies 1 word in CIO output image area​ — bits 0–15 of assigned output word), Rated load 24 V DC, 0.1 A (100 mA) per point, 1.6 A max per common (all 16 pts combined), Response time ON→OFF / OFF→ON: ≤ 0.1 ms (typical — suitable for PWM-like high-speed turn-on/off if scanned fast or via immediate refresh).
• Output type is NPN (Sink / 漏型)​ — when ON, the output transistor sinks current from the load to 0V (i.e., Load +24V → Load → Output Y□ → 0V). This is the Japanese/Asian standard​ — confirm your existing wiring! (European standard on some brands = PNP/Source; Omron CJ default = NPN).
• Occupies 1 slot (31 mm width)​ in a CJ rack (CJ1W-PA202/PA205 backplane), with built-in screw terminals (M3 — accepts 1.5 mm² / AWG 16 max typical — check manual for exact gauge).
• Compatible with CJ1M, CJ2M, CJ2H CPUs​ — addressed automatically in CX-Programmer (you assign start word — e.g., W100 → outputs = W100.00–W100.15).

Key Features

• Outputs: 16 × 24V DC NPN Transistor (Sink) — 0.1A/pt, 1.6A/common max
• Response Time: ≤ 0.1 ms (typ. ON/OFF) — supports high-speed cyclic or pulsed operation
• Diagnostics: Output status LED per point (lights when output ON); Module has PWR LED (via backplane 5V)
• Isolation: Photocoupler isolation between output & backplane; outputs are not isolated from each other (common 0V per group — OD213 has one common terminal (COM 0V)​ for all 16 pts**​ — check: actually OD211/OD213 = 16 pt NPN — terminals: 16 output terminals (Y00–Y15) + 1 common (COM/0V) shared for all 16 — be careful not to exceed 1.6A total!)
• Country of Origin: Japan (Omron Corporation)

Model & Variant Reference (Omron CJ1W Digital Output Units — Context)

⚠️ Critical Notes:

1. NPN (Sink) Wiring — Not PNP!: CJ OD units are NPN (Sink):
   • Load wiring: +24V → Load (+) → Load (–) → Output terminal Y□ → (when ON) sinks to COM (0V).
   • COM terminal​ on OD213 = 0V (DC 0V / M) — must be connected to your 24V DC power supply 0V.
     If your existing equipment/expectation is PNP (Source — output switches +24V) → this module will NOT work — you’d need a PNP version, which Omron CJ does NOT offer​ (CJ is NPN-only for DC — if you must source +24V you need an interposing relay or PNP→NPN interface). European wiring accustomed to Siemens ET200S PNP may need interposing relay.
2. Common Rating — 1.6A Total!: OD213 has ONE common (COM 0V) for all 16 outputs​ — max 1.6 A combined​ across all ON outputs. If you have 10 solenoids @ 0.05A = 0.5A OK; if many SSR or lamps causing >1.6A sum → split across multiple OD modules or use OD231 (2 commons × 1.6A each).
3. High-Speed Use: OD213 (HS) response ≤0.1 ms — good for PWM or pulsed SSR drive (e.g., from temp control pulse output). Ensure PLC scan & output refresh rate match requirement (immediate refresh or timed interrupt if doing high-freq toggling).
4. Fuse Protection: It is strongly recommended to fuse each output or group​ externally (e.g., 2A fast-blow fuse on COM feed, or per-output fuse if critical) — transistor outputs can be damaged by short-circuit despite electronic protection (some have short-circuit protection — check catalog: CJ1W-OD213 has overcurrent protection that auto-cuts & can recover after removal — but external fusing still best practice).
5. CIO Addressing: In CX-Programmer, insert CJ1W-OD213 → assign Start Output Word (e.g., W100) → physical outputs = W100.00–W100.15 (bit ON = output energized/sinking). Read back status via same word (reflects actual state after output refresh).

Warranty & After-Sales

• Factory new units: 12 months warranty
• Refurbished units: 3-6 months warranty (force ON each bit in test rig → measure 24V sink at terminal → verify LED)
• Technical support for:
  • NPN wiring confirmation (Load between +24V & Y□; COM → 0V; if you have PNP expectation → discuss interposing relay)
  • Common current de-rating (warn if total load >1.6A → suggest 2nd OD213 or OD231 with 2 commons)
  • CX-Programmer I/O address assignment (start output word — e.g., W100 → W100.00–W100.15)
  • Fusing / surge suppression recommendation (flywheel diode across DC solenoid coil — 1N4007 typical; RC snubber across AC load if mixed — but OD213 is DC only)
  • Paired module suggestions (companion input: CJ1W-ID211 16-pt 24V DC NPN input — same footprint)
  • Troubleshooting (output not ON → check COM 0V connection, PSU 24V alive, bit forced ON in monitor mode)
• Optional: CJ1W-PA202/PA205 PSU, CJ2M CPU, CJ1W-ID211 (input companion), fuse blocks, flyback diodes, 24V DC PSU (S8VK/S8JC series)
