Original Press Release:

Ascon sigmaPAC Complete Control System

Ascon is pleased to announce the release of the sigmaPAC® complete control system. Power and innovation paired with exceptional modularity and flexibility allow the sigmaPAC® to be used in the most diverse and demanding applications. Features of the sigmaPAC® include a multi function platform equipped with control functions for many types of variables (temperature, pressure, flow, level, position...), logic and sequence functions, and process calculations. The sigmaPAC® is targeted for applications with multiple parallel tasks to be managed by the same control unit. The various available interface ports include RS232 and RS485, Ethernet and major Fieldbuses to guarantee maximum connectivity..

The sigmaPAC® Control Unit is compact in size (110mm x 152mm), mounts on standard DIN rail and connects to remote modules using standard Ethernet cables with RJ45 connectors. The processor features 32 bit ARM architecture, 4 MB flash memory, 16 MB DRAM and 128 kB SRAM with battery back-up. Default interfaces include CANopen port, Ethernet 10baseT port and RS232 port, while optional interfaces include RS232/485 serial ports with Modbus RTU protocol, Profibus DP slave, CANopen slave, and DeviceNet slave. A configurable alarm relay digital output, Watchdog and Wake Up digital output and one digital input are part of the onboard I/O package. A wide variety of analog, digital and mixed I/O modules provides the flexibility to create the optimal complete control system for every application. The sigmaPAC® system with Control Unit and I/O modules allows for the development of centralized or distributed solutions without modifying or adding components
