BAScontrol20 20-point BACnet/IP Sedona Unitary Controller

Product Overview

The BAScontrol20 is a 20-point unitary controller which supports BACnet/IP and Sedona using an Ethernet connection. The controller complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs and 4 relay (20R) or triac (20T) outputs. Unique to the unit are 48 web components which link Sedona wire sheet readable/writeable data to web pages, and 24 virtual points which link Sedona wire sheet readable/writeable data to a BACnet client.

The device is fully web page-configurable, and freely programmable using Sedona's drag-and-drop programming methodology of assembling components onto a wire sheet to create applications. The unit can be programmed using Niagara Workbench AX or a third-party Sedona programming tool such as Sedona Application Editor (SAE). Rugged design, low profile, and wide temperature operation make it suitable for indoor or outdoor use.

Versatile Control Device — Unitary controller or remote Ethernet I/O

  • BACnet/IP compliant with a B-ASC device profile
  • Resident Sedona Virtual Machine (SVM)
  • Programmable via Workbench AX or Sedona Editor
  • Configurable with a common web browser
  • Direct connection to Ethernet network
  • NTP or manually-settable real-time clock
  • COV subscriptions – 14 binary and 2 analog
  • Industrial temperature operation -40°C to +75°C

Flexible Input/Output — 20-points of physical I/O

  • Eight configurable universal inputs:
    Thermistor, resistance, analog voltage, binary input, pulse inputs (4 max)
  • Four contact closure inputs
  • Four analog voltage outputs
  • Four relay or triac outputs (model specific)

Product Details

The BAScontrol20 utilizes a powerful 32-bit ARM7 processor with 512 kB of flash memory plus a 16 Mbit serial flash file system for storing configuration data and an application program.

By operating at the BACnet/IP level, the BAScontrol20 can share the same Ethernet network with supervisory controllers and operator workstations. The unit can be configured for a fixed IP address or can operate as a DHCP client receiving its IP address from a DHCP server. A real-time clock with a supercap backup allows for creating local schedules.

A 10/100 Mbps Ethernet port supports protocols such as BACnet/IP, Sedona SOX, HTTP and FTP. Configuration of universal inputs and virtual points can be accomplished using web pages. Type II and type III 10 kΩ thermistor curves and a 20 kΩ thermistor curve are resident in the unit. Current inputs can be measured using external resistors. Contact closures require a voltage-free source. Binary inputs and outputs as well as analog outputs require no configuration. The unit is powered from either a 24VAC/VDC source.
