Q2MEM-2MBSN

Q2MEM-2MBSN (MEM-2MBSN module) provides 2MB storage via Q2MEM interface, designed for reliable data retention and high-speed access in embedded systems.

Specification

SEODescription

The Q2MEM-2MBSN is a robust industrial memory module designed for data-intensive applications, featuring 2MB of non-volatile storage (Q2MEM 2MB storage) to ensure reliable data retention. This MEM-2MBSN module supports direct integration with up to 8 peripheral devices or control units through its dual-channel RS-485 interface, enabling seamless communication in automation systems. Operating within a wide voltage range of 9-36V DC and a temperature tolerance of -40°C to +85°C, it excels in harsh environments like manufacturing, energy management, and process control. Key advantages include high-speed data logging, low power consumption, and MIL-spec shock resistance, though its fixed storage capacity may require expansion modules for large-scale systems. The Q2MEM-2MBSN prioritizes industrial-grade durability while maintaining backward compatibility with legacy PLC architectures.
