MVME162PA-242LNS | Basic Information (Motorola / Emerson / Abaco)

I. Basic Details

Model: MVME162PA-242LNS

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162PA (6U VME SBC, 242 wide-temperature rugged cooling model)

Form: 6U VME dual high single-board computer

Positioning: 25MHz FPU, 8MB, 2IP, single Ethernet, no SCSI, -40~+85°C, rugged, with original cooling fins

II. Core Hardware (Same as 242 Full Series)

CPU: MC68040, 25 MHz (with FPU hardware floating-point)

DRAM: 8MB (parity check)

SRAM: 512KB (battery backup, power-off retention)

Flash: 1MB (162Bug firmware)

RTC/NVRAM: 8K×8, battery backup clock

III. Built-in I/O (Same as 242 Full Series: No SCSI)

✅ Single 10Mbps Ethernet (DMA)

✅ 2× Serial Ports (EIA-232-D, Console + User)

✅ 2× IndustryPack (IP) Expansion Slots (Independent DMA)

❌ No SCSI Interface (242 Full Series does not have SCSI)

✅ 6× 32-bit Timers + Watchdog

IV. Environment and Suffix (L = Encapsulation, N = Heat Sink, S = Wide Temperature)

Power Supply: +5V, Typical 2.0A

Operating Temperature: -40°C ~ +85°C (Industrial wide temperature ✅)

Encapsulation: ✅ Anti-vibration, reinforced welding (vibration environment)

Heat Dissipation: ✅ Original factory with metal heat sink (LNS exclusive)

Wide Temperature: ✅ Supports harsh environments of low/ high temperatures

Size/Weight: 6U VME, Approximately 0.9kg (including heat sink)

V. 242 Family Suffix Mnemonic (Including LNS)

242: 0~+70°C, No Encapsulation, No Heat Sink → Standard Version

242L: 0~+70°C, Encapsulation, No Heat Sink → Normal Temperature Encapsulation

242E: -40~+85°C, No Encapsulation, No Heat Sink → Wide Temperature

242LE/SE: -40~+85°C, Encapsulation, No Heat Sink → Wide Temperature Encapsulation

242LNS: -40~+85°C, Encapsulation, Original Factory Heat Sink → Wide Temperature Encapsulation High-End (Your Model)

Rule: L = Encapsulation, E/S = Wide Temperature, N = Heat Sink; 242 Full Series has no SCSI

VI. Core Differences between LNS and LE/SE (Commonly Asked by Customers)

242LE/SE: Wide Temperature + Encapsulation, No Heat Sink (Depend on the chassis ventilation)

242LNS: Wide Temperature + Encapsulation + Built-in Heat Sink (More stable in high/enclosed chassis under high temperature)

VII. Typical Applications

Vehicle / Ship / Rail Transit (Wide Temperature + Vibration + Enclosed Chassis)

Outdoor Equipment, High Temperature Workshop, Air-conditioned Cabinet-less (Priority on Heat Dissipation)

High-reliability Industrial Control, Vibration Equipment, Machine Tools, Robots (Wide Temperature + Heat Dissipation)

No SCSI, No 4IP, but requires wide temperature + encapsulation + heat dissipation for high-end requirements
