Description
OMRON C200H‑OC221
Technical Specifications: Total output points: 16 points; output form: independent mechanical relay SPDT contact per channel; rated contact capacity resistive load AC250V 2A, DC24V 2A; maximum output response time 15 ms; no built‑in short‑circuit protection for output channels; dielectric‑withstand voltage AC1000V 1‑minute between external terminals and ground; backplane bus power consumption 140mA at DC5V; mechanical service life ≥10 000 000 operations; electrical service life ≥300 000 operations under rated resistive‑load conditions; operating temperature 0‑55°C; storage temperature ‑20‑75°C; operating humidity 10‑90%RH without condensation; rack‑slot installation; weight 320g; LED status indicator for each output channel.
Functional Features: 16‑channel independent relay‑contact output; each channel provides both normally‑open and normally‑closed dry‑contact signal; mechanical relay realizes complete electrical isolation between PLC internal logic circuit and field‑load circuit; independent LED status indicator for each output channel to reflect relay‑action state; compatible with AC‑type and DC‑type field‑load equipment; full compatibility with C200H‑series backplane‑bus architecture.
Application Scenarios: Solenoid‑valve drive inside industrial automation cabinets; auxiliary‑contactor coil control; indicator‑lamp and alarm‑loop output control; spare‑part replacement for legacy C200H‑series automation installations.
Performance Parameters: Mechanical relay‑isolation structure blocks field‑load‑side surge interference; meets IEC industrial‑control‑component electromagnetic‑compatibility standards; vibration‑resistance and shock‑resistance comply with cabinet‑mount‑equipment test criteria; supports continuous 24‑hour cabinet‑internal operation under non‑overload load conditions.
Material Composition: Black V0 flame‑retardant engineering‑plastic housing; internal FR‑4 multilayer glass‑fiber printed‑circuit board; miniature signal‑relay assemblies fitted with silver‑alloy contact points; 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 physical profile; gold‑plated edge‑connector on rear housing surface interfaces with C200H rack backplane bus; front‑panel screw‑terminal block for field‑load wiring; LED indicator array for 16 output channels arranged on front‑panel surface; side locking clips fasten module firmly into rack‑slot position.
Working Principle: C200H‑series CPU refreshes output‑logic data onto rack backplane bus. ‑OC221 receives logic commands through rear‑side gold‑plated contacts. When output command is ON, corresponding‑channel internal relay coil energizes, relay contact pulls in and completes external‑load‑circuit conduction. Matching‑channel front‑panel LED indicator illuminates synchronously. When output command changes to OFF, relay coil de‑energizes, contact resets and external‑load circuit disconnects, LED indicator extinguishes.
Installation Requirements: Install ‑OC221 into idle slot on ‑series main rack or expansion rack; secure ‑series rack onto cabinet DIN rail; install surge‑absorbing components in parallel across terminals of inductive‑type field loads; physically separate load‑output cables from high‑power motor‑drive cables; implement reliable protective grounding for control cabinet.
Usage Notes: Module hot‑swap operation is strictly forbidden; single‑channel load current shall never exceed 2A rated contact capacity; periodic inspection for relay‑contact abrasion under high‑frequency switching‑cycle conditions; do not deploy in environments with condensation or corrosive gas; perform periodic inspection of screw‑terminal fastening torque.
