Product Performance

Fast logic processing speed: The 32-bit processor supports a ladder diagram execution speed of 0.1ms/kstep, enabling simultaneous operation of over 100 control loops to meet the real-time control needs of small-to-medium production lines. Rapid I/O response: Digital input response time ≤1ms, analog sampling cycle ≤10ms, ensuring real-time acquisition and control of process variables such as temperature and pressure.

Flexible expansion capability: Supports up to 8 expansion modules (including digital, analog, and special function modules), expandable to 128 digital I/O and 32 analog I/O, adapting to control scenarios of different scales. Comprehensive diagnostic coverage: Self-diagnostic functions can real-time monitor core hardware and I/O channel status, with fault location accuracy down to the channel level, reducing maintenance troubleshooting time.

High hardware stability: The fanless design reduces the risk of mechanical failures; industrial-grade components and wide-temperature design ensure a Mean Time Between Failures (MTBF) ≥1.5×10⁶ hours (MIL-HDBK-217F standard, 25℃ environment), enabling continuous and stable operation in dusty, vibrating, and other industrial scenarios. Strong software compatibility: Fully compatible with Reliance AutoMax programming software, supporting online programming, debugging, and firmware upgrades, with parameter updates completed without interrupting the system.
