QA-16 Data Acquisition System

The QA-16 is an inexpensive 16-point data acquisition system for use on single burner, and small multiple burner combustion systems. Two versions of the controller are made; the QA-16 has 8 discrete (120 VAC) inputs and 8 analog (0 to 12 VDC) inputs. The QA-16D version has 16 discrete inputs and no analog inputs. The QA-16 interfaces with the QD485 LCD display to provide programmable, customized status, diagnostic, and troubleshooting messages. Two QA-16 processors can be combined to double the amount of available I/O.

Overview

The QA-16 is an inexpensive sixteen point data acquisition system for use on single burner, and small multiple burner combustion systems. The QA-16 interfaces with the 5003-QD485 LCD display to provide programmable, customized status, diagnostic, and trouble shooting messages. First-out annunciations and other messages can be customized to fit the application. Unlike typical annunciators, the QA-16 can receive flame input and other analog signals to provide visibility for these inputs as well.

Features

• Operator interface key pad on front of unit
• 1/8th DIN standard size for easy mounting in control panels
• Built-in 120 VAC 50/60 Hz supply

QA-16 Features

• Digital annunciation of up to 8 discrete inputs and 8 analog inputs (QA-16) or 16 discrete inputs only (QA-16D).
  

Specifications

QA-16

Microprocessor Data Acquisition System: System shall be capable of monitoring up to 8 discrete (limit) inputs and up to 8 analog (flame signal) inputs. First-out annunciation and English language messages shall be indicated on a 2 x 16 LCD display suitable for flush-mounting in an enclosure front. The controller shall provide historical logging of past alarms and communicate via RS-232 connection. Display messages and trip logic shall be customizable for each application. One relay output shall be supplied to provide a common alarm contact, trip indication, or other external function. For increase input/output capability, two data acquisition modules shall interface to a common display, providing a total of sixteen discrete inputs and sixteen analog inputs.

Manufacturer: Data acquisition system shall consist of one or two Preferred Instruments QA-16 modules interfaced to a Preferred Instruments QD485 display module. System shall be programmed by Preferred Utilities Mfg. of Danbury, CT.
