ASIC/2-8540 Configurable Controller

ASIC/2-8540 Data Sheet

A powerful configurable controller with lower I/O count than the ASIC/2-7540. The ASIC/2-8540 controller is fully configurable for HVAC/R and similar process applications. Suited for automation of small facilities, controlling large equipment, supervisory duties, multi-zone and other applications. An optional Ethernet expansion card is available. Supports Modbus protocol, acting as the Modbus RTU Master.

The ASIC/2-8540 features a powerful and intuitive graphical configuration interface, with an extensive set of objects available to speed the configuration and commissioning process. The controller configuration is stored onboard, and the 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. Configuration data is preserved through power outages.

The controller can be remotely accessed using either Ethernet or modem. The ASIC/2-8540 can initiate outbound modem dialout in order to deliver alarm or event notifications. Configured using ASI Visual Expert graphical configuration software.

There are 8 universal inputs which can be multiplexed to achieve up to 32 digital inputs total. The controller includes 8 relay outputs and 4 analog outputs. An optional ETH-8540 Ethernet expansion board connects directly to the motherboard to provide direct Ethernet UDP/IP connectivity at the board level.

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.
