Product Performance

Adopting Intel 486 DX66 processor with computing speed up to 33 MIPS, it has a built-in floating-point unit that can efficiently handle mathematical operations and logical judgment tasks in industrial control. The 8KB L1 cache reduces data access latency, and with up to 64MB memory, it supports multi-task program operation with system response time ≤10ms.

The ISA bus expansion capability supports connecting industrial I/O modules, data acquisition cards and other peripherals, adapting to industrial equipment such as temperature sensors and PLCs. The fanless design reduces mechanical failure points, maintaining stable performance in a wide temperature range of -20°C to 60°C, meeting the harsh operating requirements of industrial sites.

Compatible with early operating systems such as DOS 6.22, Windows 95 and OS/2, it supports assembly language and C language development tools commonly used in the industrial control field, enabling rapid deployment of embedded control programs. The mean time between failures (MTBF) is ≥500,000 hours, complying with industrial-grade long-life operation standards.
