The ASIC/2-7540 features a powerful and intuitive graphical configuration interface, with an extensive library of objects to speed configuration and live data display to help with commissioning. The controller configuration is stored onboard and preserved through power outages. Configuration data can be uploaded to any instance of ASI Controls Visual Expert configuration software, either through plug-in connectivity on the jobsite or remotely over a network connection.
The ASIC/2-7540 system controllers offer drag and drop configuration and programming of control sequences for HVAC Control, Energy Management, Building Automation and similar applications. The two separate communication busses support network and supervisory control functionality. Suitable for control of larger mechanical equipment, control panels, standalone handling of small facilities, networked control of very large facilities, and other demanding control applications.
An onboard USB port offers a low-cost Ethernet connectivity option for standalone controllers. An Ethernet or modem connection provides remote access for changing configuration or examining status. The controller can initiate modem dialout to deliver alarm or event notifications. 16 universal inputs are provided, these can be multiplexed to achieve up to 64 inputs in total. Includes 12 relay outputs and 8 analog outputs.
The controller can act as the Modbus RTU Master to monitor and control Modbus RTU slave devices such as variable speed drives, power meters, digital communicating thermostats, lighting controls, pressure monitors, and other Modbus-enabled devices. Installing an ASI Controls Energy Management System with VFD's and other Modbus-enabled energy saving devices can reduce building energy consumption and lower operating costs. Native features include a configurable demand limiting algorithm which offers automated setpoint adjustment and equipment deactivation options in order to shed load as needed to satisfy tariff, distribution, or other peak load constraints, as well as an optimum start sequence.
A battery-backed real-time clock is one of the standard features of all ASIC/2 controllers, providing true stand-alone capability. The schedule and calendar features allow special time schedules to be setup, providing flexibility for projects such as retail outlets, educational facilities and other settings with variable occupancy.
Applications requiring a smaller controller footprint and/or less IO can use the ASIC/2-8540 with 8 universal inputs and 8 Binary + 4 Analog outputs, or the ASIC/2-8540-BAC with BACnet MS/TP interface. The JASIC Open Systems line also offers network supervisory controllers with embedded web servers along with drivers for BACnet, Modbus, LON, and other common protocols.
