Supervisory Controllers and Embedded Web Servers

ASI Controls supervisory and network controllers provide digital control for in many applications. Whether you need to control equipment such as an AHU or Chiller, supervise multiple floors of VAV controllers in a building, or provide the head end device for a system incorporating hundreds of sub-networked controllers. Customers are able to provide solutions combining components from the reliabile, rugged ASIC/2 line with the interoperable, interconnectable JASIC Open Systems line.

ASIC/2 and JASIC Open Systems controllers provide options when you need more features than the economical pre-programmed ASIC/1 controllers offer, such as managing a sub-network of pre-programmed controllers, embedding the web front end in the control system, or holiday scheduling that innately recognizes Thanksgiving, Labor Day, Memorial Day etc. In addition to standard features like HVAC Control, Demand Limiting, Lighting control, scheduling, supervisory control and timekeeping, the ASIC/2 configurable controllers have almost unlimited flexibility with features that include:

  • Energy management including demand control and optimum start
  • Alarm reporting, including dial-out to monitoring software
  • Simple on-off, delayed start, optimal start, rotating start
  • Complex control sequences including PID Loops
  • JASIC interfaces for BACnet, Modbus, OPC, LON interoperability
  • JASIC drivers for automated demand response, databases, legacy DDC,...
  • Local data logging for trending and reporting
  • Weekends, daylight savings, holidays, special events schedules

The JASIC Open Systems line is powered by the Tridium NiagaraAX Framework™, enabling control solutions combining ASI Controls legendary performance and reliability with open systems interoperability. JASIC interoperability provides options for the most cost-effective upgrades and retrofits of existing control systems, and offers the option to integrate a legacy ASI control system into a BACnet front end using a BACport network interface.

The ASIC/2 line leverages a decade of experience in providing powerful programmable controllers. Devices are programmed in a drag and drop visual environment using ASI Visual Expert software. Any ASIC/2 controller can act as Modbus RTU Master on the local bus.
