The ASIC/3-6115 BACnet programmable controller combines the proven functionality of an ASI terminal controller with the full power of the ASIC/3 object based system controllers.
The ASIC/3-6115 provides the full range of ASIC/3 software objects for developing custom control sequences, and support for the WS-061 wall sensor. It has a switching power supply for AC operation and flash memory for program and data storage. Firmware is easily upgradable using ASI Visual Expert or by inserting a USB flash drive into the USB host port.
The controller is easily configured using ASI Visual Expert configuration software that links ready-made objects including scheduling, logic, PID control, alarming, optimum start, trending, run-time accumulation, and electrical demand management. The ASIC/3 has a software clock and allows special events, holidays, and schedules to be defined in advance. Configuration data is stored in non-volatile memory that is retained through power system loss.
The ASIC/3-6115 controller has an RS-485 port that is used to network multiple ASIC/3 controllers via ASI protocol or can optionally support BACnet MS/TP. No central system is needed to supervise the controller. Red and green LEDs indicate the controller’s receive and transmit communications.
The ASIC/3 can operate as part of a larger communicating control network. The ASIC/3 also features a full-speed 12 Mbps USB Device connection for service in the field. The RS-485 connection supports ASI protocol baud rates up to 38,400 bps, and standard BACnet MSTP baud rates up to 76,800 bps.
The controller can send notify messages through the RS-485 bus to a computer running ASI Weblink software. Temperatures, setpoints, and other controller data may be easily reported to ASI WebLink, Niagara, Intellifront, or other supervisory software.
