High-Performance Processing
The ASM84A002 features a 16-bit microcontroller that executes Boolean logic in just 0.25 ms per 1K instructions. This speed ensures rapid scan cycles for time-critical control loops and fast interrupt responses. The processor handles complex mathematical operations and data manipulation with equal efficiency. Consequently, this CPU module supports sophisticated applications such as motion coordination and process control.
Comprehensive Memory Resources
This processor module provides 128 KB of battery-backed RAM for user programs and system variables. The 512 KB Flash EPROM stores the operating system and firmware permanently. The module also includes 1,024 internal data registers and 256 timers and counters. These ample resources accommodate large, complex applications without requiring external memory expansion.
Integrated I/O and Connectivity
The ASM84A002 integrates 16 digital inputs and 8 digital outputs directly on the module. These onboard points handle simple monitoring and control tasks without additional I/O modules. The CPU also offers dual communication ports for system integration. The RS-232 port connects to programming terminals, while the RS-485 port supports Modbus networking with field devices.
Robust Data Retention
This CPU module incorporates a replaceable 3.6 V lithium battery that retains RAM data for up to three months. This battery backup protects critical program logic, process parameters, and historical data during power outages. The module provides a low-battery warning LED for proactive replacement scheduling. Therefore, you can perform maintenance without risking data loss or program corruption.
Durable Design for Industrial Environments
The ASM84A002 operates reliably across a 0 °C to 60 °C temperature range for versatile deployment. Its compact dimensions and 0.45 kg weight simplify mounting on standard DIN rails. The rugged construction resists vibration, humidity, and electrical noise common in factory settings. This durability ensures consistent performance and long service life in your automation system.
