• Battery-backed clock

The ASIC/2-8540-BAC is a programmable controller with a BACnet MS/TP interface and a small footprint. The BACnet-MS/TP interface offers convenient options to tie into existing BACnet networks, and provides a complement to the ASI BACport BACnet/IP interface for OEM control of AHU's, Chillers, Boilers, or other mechanical systems.

A powerful fully configurable controller for HVAC/R and similar process applications. Suited for automation of small facilities, controlling large equipment, supervisory duties, multi-zone and other applications. Can act as Modbus RTU Master to monitor and control Modbus RTU slave devices on the local bus.

The ASIC/2-8540 features a powerful and intuitive graphical configuration interface, with an extensive set of objects available for configuration and live data display to simplify commissioning. Controller configuration information is stored onboard, and 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. Configuration data is preserved through power outages.

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.

The controller can be remotely accessed using either Ethernet or modem. The ASIC/2-8540 can initiate modem dialout in order to deliver alarm and event notifications, or annunciate through an Ethernet network. There are 8 universal inputs, which can be multiplexed for a total of up to 32 digital inputs. The controller includes 8 relay outputs and 4 analog outputs. A battery-backed real-time clock is a standard feature on all ASIC/2 controllers, providing true stand-alone capability. The schedule and calendar features allow special time schedules to be configured years in advance, a convenient option for projects such as retail outlets, educational facilities and other settings with variable occupancy

The FlashBAC In-field BACnet Flash Programmer allows upgrade of BAC/2-MSTP firmware over a BACnet network, transferring program data using an auto-discovered BACnet/IP router.
