Product Performance

The kit adopts high-contrast transmissive LCD display with 640×200 resolution to ensure clear presentation of alarm event lists and channel data. Backlight adjustment function adapts to different lighting environments. 8 groups of tri-color LED indicators map system status in real time, with independent flashing of new alarm LED, ensuring alarm visual response time ≤1 second.

High-speed data interaction with 3500 rack is realized through RS422 interface, supporting Modbus protocol integration into third-party control systems with data transmission delay ≤1 second. Four mounting methods meet diversified needs from local cabinet monitoring to remote control room deployment, with maximum 4000-foot cable distance adapting to large industrial plant layouts.

Wide temperature design and EMC optimization ensure stable operation in -20°C to 65°C environment, with mean time between failures (MTBF) ≥300,000 hours. The display unit works with Display Interface Module (DIM) to support online configuration updates and fault self-diagnosis, with diagnostic information intuitively fed back through LED indicators.
