OMRON C200H‑IA222
Technical Specifications: Number of input points: 16 points; rated input voltage AC100‑120V 50/60Hz; allowable operating voltage range AC85‑132V; typical input current 10mA per point; ON‑state trigger voltage minimum AC60V; OFF‑state reset voltage maximum AC20V; response‑on time maximum 25 ms; response‑off time maximum 45 ms; dielectric‑withstand voltage AC1000V 1‑minute between external terminals and ground; backplane bus power consumption 100mA at DC5V; operating temperature 0‑55°C; storage temperature ‑20‑75°C; operating humidity 10‑90%RH without condensation; rack‑slot installation; weight 250g; LED status indicator for each input channel.
Functional Features: 16‑channel AC‑signal input for industrial‑field AC switching‑signal acquisition; built‑in optocoupler isolation circuit isolates field AC circuit from PLC internal logic circuit; independent LED status indicator for each input channel to visually reflect signal ON‑OFF state; common‑terminal group design simplifies field multi‑point AC‑signal wiring; full compatibility with C200H‑series CPU backplane‑bus architecture.
Application Scenarios: AC‑voltage switch‑signal collection inside factory automation cabinets; auxiliary‑relay contact‑status acquisition; legacy‑equipment AC‑sensor signal access; spare‑part replacement for legacy C200H‑series automation installations.
Performance Parameters: Optocoupler isolation blocks field‑side surge and noise interference; meets IEC industrial‑control‑component electromagnetic‑compatibility standards; vibration‑resistance and shock‑resistance conform to cabinet‑mount‑equipment test criteria; supports continuous 24‑hour operation within control‑cabinet environments.
Material Composition: Black V0 flame‑retardant engineering‑plastic housing; internal FR‑4 multilayer glass‑fiber printed‑circuit board; optocoupler isolation chips; brass nickel‑plated screw‑terminal block; gold‑plated backplane edge‑connector contacts; high‑brightness LED channel‑status indicators.
Structural Features: Standard C200H‑series rack‑slot form factor; gold‑plated edge‑connector on rear housing surface connects to C200H rack backplane bus; front‑panel screw‑terminal block for field AC‑signal wiring; one LED indicator assigned to each input channel on front‑panel surface; side locking clips fasten module firmly into rack‑slot position.
Working Principle: Field AC100‑120V switching‑signal connects to module screw‑terminal block. When input‑terminal voltage reaches ON‑state trigger threshold, internal optocoupler conducts and converts AC switching‑state into DC logic‑level signal. Corresponding‑channel front‑panel LED indicator illuminates simultaneously. Logic‑state signal transmits through internal circuit and gold‑plated backplane contacts to C200H‑series CPU for user‑program reading. When field AC‑signal disappears, optocoupler cuts off and LED indicator extinguishes.
Installation Requirements: Install ‑IA222 into idle slot on ‑series main rack or expansion rack; secure ‑series rack onto cabinet DIN rail; field AC‑signal wiring must comply with local electrical‑safety codes; separate AC‑input signal cables from high‑power motor‑drive cables; implement reliable protective grounding for control cabinet.
Usage Notes: Module hot‑swap operation is strictly forbidden; external input‑voltage shall never exceed AC132V upper limit; check wiring correctness before power‑on operation; do not deploy in environments with condensation or corrosive gas; perform periodic inspection of screw‑terminal fastening torque.
