Description
Densan JDVE‑SH7604 (9271)
Technical Specifications: Bus standard: VME ANSI/IEEE 1014 Mechanical format: 6U single‑slot VME plug‑in module Signal type: Galvanically isolated digital input and digital output composite channel Field‑side signal rated voltage: 24VDC Galvanic isolation withstand voltage: 1500VAC between field circuit and VME bus logic circuit Per‑channel output continuous load current: 0.25A Operating temperature: 0 ℃ to 55 ℃ Storage temperature: -40 ℃ to 85 ℃ Relative humidity: 5% to 95% non‑condensing Protection grade: IP20 Backplane connector: DIN 41612 J1 connector
Functional Features: Composite multi‑channel optocoupler‑isolated digital input and digital output channels. Each signal channel corresponds to independent front‑panel LED status indicator lamp. Hardware signal debounce circuit eliminates jitter interference generated by mechanical contact bounce of field switches. Every output channel integrates hardware over‑current and short‑circuit protection components. Built‑in surge‑suppression EMC filter circuit for each field‑connected terminal. Complete power‑on hardware self‑diagnosis routine covers isolation circuit and channel drive circuit. Supports VME bus interrupt signal generation when input signal state changes or output channel fault occurs. VME bus register access for reading input status and writing output control value. Channel‑wise fault status readable via mapped hardware registers.
Application Scenarios: Semiconductor equipment safety interlock signal acquisition and output control cabinet, automated assembly‑line discrete signal interaction unit, industrial machinery peripheral sensor and actuator integrated control rack, automated test equipment composite I/O signal processing cabinet, special‑purpose industrial machinery VME‑based control system, equipment upgrade replacement project matching original Densan VME hardware series.
Performance Parameters: Digital input channel signal response time less than 0.8ms Digital output channel action response time less than 1ms Hardware debounce filtering time configurable by on‑board component setting Vibration resistance: 10Hz‑150Hz, constant amplitude 0.5g Shock resistance: 10g peak acceleration, 11ms pulse duration MTBF value: 194000 hours under standard cabinet cooling operating environment
Material Composition: Front panel material adopts anti‑oxidation surface‑treated aluminum alloy. Main printed‑circuit‑board substrate uses high‑Tg FR‑4 glass‑fiber epoxy material complying with UL94‑V0 flame‑retardant standard. Backplane connector contact pins apply gold‑plated copper‑alloy material. Signal isolation components adopt industrial‑grade optocoupler chips. Drive chips, filtering and protection components are selected according to full industrial temperature specification. Fastening hardware consists of nickel‑plated carbon‑steel screws and spring‑loaded ejector latches.
Structural Features: Standard 6U single‑slot VME plug‑in mechanical construction. Metal front panel fitted with locking ejector handles and channel‑by‑channel LED status indicator array. Rear side is equipped with multi‑row high‑density DIN41612 gold‑plated connector for mating with VME rack backplane. Printed‑circuit‑board layout sets strict electrical isolation barrier to separate field signal circuit region and VME‑side digital logic region. Every input and output channel is configured with independent filtering, decoupling and protection components. On‑board small‑size jumper blocks are reserved for partial function configuration setting. Ventilation cutouts on front panel realize passive convection heat dissipation for internal circuit components.
