Introduction

The ioPAC 8500 Series modular controllers use an Arm9 industrial-grade CPU for the system, and Arm Cortex™ M4 CPUs for the modules. The controllers have 2, 5, or 9 I/O slots for 85M Series modules and the dual CPU architecture supports a 5 kHz (per channel) analog input sampling rate, pre-recording of analog input data, and timestamping with millisecond granularity. Moreover, the ioPAC 8500 supports C/C++ or IEC 61131-3 programming, rail-level surge and ESD protection, a -40 to 75°C operating temperature range, vibration protection, hot-swappable modules, two 10/100 Mbps Ethernet ports with two MACs (with port trunking capability), and two 3-in-1 serial ports. Accompanied by Moxa’s MX-AOPC UA Server and MX-AOPC UA Logger data integration software, the ioPAC 8500 Series provides a comprehensive solution for data acquisition and control applications in harsh environments.

High Sampling Rate

Moxa’s ioPAC 8500 controllers use an Arm9 industrial-grade CPU, and the dual CPU architecture supports up to a 5 kHz (per channel) analog input sampling rate, giving engineers the analog data precision they need to correctly analyze events after they have occurred.

Analog Input Prerecord Feature

The prerecord feature allows the device to continuously record analog input data before an event is triggered. This is a major improvement over products that only start logging data after an event has occurred, because these conventional approaches can often lead to the loss of critical data due to network latency during the event.

Millisecond Timestamp Granularity

Millisecond timestamp granularity is a powerful aid in post-event analysis and troubleshooting. For example, if an emergency triggers 10 separate I/O events within a 10-millisecond time interval, you will still be able to clearly identify the sequence in which the events occurred, even if the I/O events are recorded by different modules.

Hot-Swappable Modular I/O

The controller lets you hot-swap I/O modules, allowing engineers to quickly and easily install and replace modules in the field, reducing maintenance costs and streamlining maintenance procedures.
