Densan DVE‑OP60C‑20A (9274)
Technical Specifications: Bus compliance: VME ANSI/IEEE 1014 Mechanical format: 6U single‑slot VME plug‑in module Signal category: optocoupler‑isolated digital output Field‑circuit rated operating voltage: 24 VDC Per‑channel maximum output current: 0.2 A Galvanic isolation withstand voltage: 1500 VAC between field side and VME bus side Operating temperature: 0 ℃‑55 ℃ Storage temperature: -40 ℃‑85 ℃ Relative humidity: 5%‑95% non‑condensing Protection grade: IP20 Backplane connector: DIN 41612 J1
Functional Features: High‑density multi‑channel optocoupler‑isolated digital output. Per‑channel front‑panel LED indicator reflecting output‑state status. Independent hardware short‑circuit and over‑current protection for each output loop. Power‑on complete hardware self‑diagnosis function. VME bus register access for output‑state configuration and fault‑status reading. Built‑in surge‑suppression components for field output terminals. Support VME bus interrupt generation for fault‑event notification.
Application Scenarios: Semiconductor‑manufacturing‑equipment actuator control cabinet, automated assembly‑line switching‑output control, industrial‑equipment solenoid‑valve drive control, automated‑test‑equipment VME‑based I/O rack, special‑purpose automated‑machinery discrete‑output control unit.
Performance Parameters: Output channel response time: less than 1 ms Per‑channel continuous allowable load current: 0.2 A Vibration resistance: 10 Hz‑150 Hz, 0.5 g Shock resistance: 10 g peak acceleration, 11 ms pulse duration MTBF value: 190000 hours
Material Composition: Front‑panel material is surface‑treated anti‑oxidation aluminum alloy. Main printed‑circuit‑board uses FR‑4 high‑Tg glass‑fiber epoxy substrate. Backplane‑connector pins adopt gold‑plated copper‑alloy. Isolation optocoupler chips and protection components adopt industrial‑grade specification. Fastening hardware uses nickel‑plated steel.
Structural Features: Standard 6U single‑slot VME plug‑in structure. Metal front panel fitted with locking ejector handles and multi‑group LED status indicators. Rear high‑density DIN gold‑plated connector mates with VME rack backplane. PCB layout implements strict isolation barrier separating field‑output circuit region and VME bus logic region. Every output channel is fitted with independent protection and decoupling components. Ventilation slots on front panel support passive heat dissipation.
Working Principle: VME main controller writes target output‑state value to DVE‑OP60C‑20A internal registers through VME backplane bus. Logic circuit drives optocoupler isolation devices, optocoupler controls conducting and cutting‑off status of field‑side output loop. When short‑circuit or over‑current fault emerges on field load loop, on‑board hardware protection circuit activates immediately. Fault status can be read by accessing VME‑mapped hardware registers. Front‑panel LED lamps directly display real‑time on‑off status for each output channel.
Installation Requirements: Insert DVE‑OP60C‑20A module into designated slot of 6U VME rack chassis. Lock ejector handles and tighten front‑panel mounting screws. Maintain sufficient ventilation clearance inside control cabinet. Deploy shielded cables for field‑output‑loop wiring. Keep field‑output cables physically separated from high‑voltage power cables. Disconnect rack main power supply before inserting or removing this board. Complete static‑elimination operation before touching bare printed‑circuit‑board surface.
Precautions for Use: Never connect field‑side load exceeding per‑channel rated current value. Wear anti‑static wristband during maintenance and replacement work. Keep ventilation openings clean without dust accumulation. Do not install in environment with corrosive gas. Periodically inspect field‑wiring terminal tightness and connector contact performance.
