Detailed Technical Specifications

Core Processor & Storage Configuration

Built with industrial-grade dual-core processor architecture, PM866AK01 provides enhanced arithmetic efficiency to execute thousands of Boolean instructions and complex PID closed-loop calculations in short cycles, greatly improving real-time response for high-speed production lines. Standard equipped with 2GB high-speed industrial RAM for loading user control programs, real-time variable data and temporary operation logs, alongside 4GB non-volatile Flash memory for permanent storage of application software, system configuration parameters and long-period historical trend data without frequent external backup devices. An onboard replaceable lithium backup battery safeguards critical configuration data from loss under unexpected power outage, enabling quick system recovery after power restoration. The controller supports over 35 user-defined prioritized tasks to allocate computing resources rationally between fast field closed-loop control and low-frequency background data recording.

Bus Expansion & Multi-Protocol Communication

Via built-in Modulebus backplane bus, standalone controller can expand up to 96 sets of S800 series analog and digital I/O modules; under master-slave redundant deployment, it supports 84 I/O modules to ensure backup safety. Reserved CEX expansion bus allows installation of up to 12 external communication modules to expand abundant fieldbus interfaces. Dual independent 10/100Mbps self-adaptive Ethernet ports follow IEEE802.3 standard and support RNRP redundant network protocol to construct fault-tolerant control network, while two isolated RS232 serial ports serve local program download and field equipment debugging separately. Matching external communication cards enables seamless data interconnection with third-party PLC and field instruments via Modbus TCP, PROFIBUS DP and mainstream industrial protocols. Rated working power is 24VDC with wide input range from 19.2VDC to 30VDC, typical power consumption is controlled within 5.5W.

Mechanical & Environmental Index

Overall dimension measures 186mm×119mm×135mm with net weight around 1.2kg, adopting standard DIN rail clamping installation for quick cabinet mounting and hot-swap maintenance. Front panel reaches IP20 protection grade to block floating cabinet dust and avoid accidental contact with internal live terminals. Rated continuous working ambient temperature ranges +5℃~+55℃, storage temperature spans -40℃~+70℃, applicable working humidity 5%~95% non-condensing RH. Approved with CE and UL certification, the module keeps stable operation under strong electromagnetic interference near high-power inverters and large industrial drive motors.

Core Advantages & Industrial Application
