Up to 136 relays may be controlled or 136 status inputs may be monitored (or combinations) with the addition of the optional expansion ports and the EX-8M Expansion Module (or EXM-8, EXM-16 or EXM-32 Relay I/O Expansion Modules). The 8 bit inputs (ADC-4U8) provide 256 increments of measurement each. The 10 bit inputs (ADC-4U10) provide 1,024 increments of measurement each. The 12 bit inputs (ADC-4U12) provide 4,096 increments of measurement each. The EN-D Instrument Case may be used to house the ADC-4U if an enclosure is required. Includes free event notification software for Smart phones (text message alerts). LabVIEW compatible, includes LabVIEW VI, graphic software example and DLL library. Software interface, driver, data logger software, remote network/Wi-Fi software and source code examples included on CD. The ADC-4U series is also available in WiFi version (ADC4-WIFI), Ethernet version (ADC4-ENET), RS-232 version (ADC4-RS232) or RS-485 version (ADC4-RS485).

ADC-16 DESCRIPTION

The ADC-16 A to D converter provides two separate 8 channel analog input ports (expandable to 48 analog inputs) which allow input of a wide variety of analog information into a conventional PC. Applications include temperature input (requires TE-8 temperature input conversion and sensors) and input of energy usage or electrical demand (requires watt transducer and current transformer). Other uses include input of pressure, light, voltage, weight, potentiometer movement, strain gauges, etc. (minimal external hardware required). The ADC-16 is very useful as a Data Logger or as an Electronic Chart Recorder. The data logging software for Windows which is provided with the ADC-16, allows the user to export data files into Excel or other programs to generate spreadsheets, charts, graphs etc. The ADC-16 may be used in battery management systems to monitor and control battery voltage levels and system operating characteristics. The ADC-16 also has many applications in the home automation field. Connection of a modem will allow these functions to be monitored from a remote site via telephone line (the EX-16 may be used for remote relay control) or use an Internet connection. The A/D output is represented as a single byte number (0 to 255 decimal) with 8 bit resolution or in two byte format (0 to 1023 decimal) with 10 bit resolution. Voltage inputs of 5 millivolts or higher per increment require no additional hardware. The VA-1 or VA-2 Precision Instrumentation Amp may be used to input lower millivolt signal levels, for input scaling or to input differential signals. Each of the two analog input ports has an adjustable voltage reference input which allows the analog voltage input level to be adjusted. The default level is 0 to 5 volts DC single ended (20 millivolt resolution, 8 bit). The addition of an external voltage reference will allow greater resolution and lower voltage input levels. EXAMPLE: A 1.2 volt reference will provide a voltage input level of 0 to 1.2 volts (5 millivolt resolution, 8 bit). Inputs can be ratio metric or standard volt. The ADC-16 A/D converter provides an output expansion port to control up to 112 relays (using EX-16 or EX-32 expansion cards) and an input expansion port which allows for expansion to 48 analog inputs or an additional 128 status (digital) inputs (using AD-16 or ST-32 expansion card). The TE-8 temperature input conversion may be used for temperature input. Includes free event notification software for Smart phones (text message alerts).

About Resolution... 8, 10 or 12 bit?

ADC-4 A to D CONVERTER...The ADC-4 provides four 12 bit analog inputs with an optional 8 channel port #2 of 8 or 10 bit resolution. The ADC-4 features the Siemens 12 bit A/D converter IC with an on-chip micro controller and memory for auto calibration. Total unadjusted error is plus or minus 1/2 LSB with no missing codes. The ADC-4 is identical to the ADC-16 in physical size and layout, I/O functions and expansion capability and provides both the relay expansion and input expansion ports. Analog port #2 may be converted for temperature input using the TE-8. Port #1 is used for connection of the four 12 bit inputs via a shielded DB-9 connector. The A/D output is represented in two byte format (0 to 4095 decimal) in 4,096 increments. Voltage input range is fixed at 0 to 5 VDC single ended. Use the VA-1 or VA-2 Precision Instrumentation Amplifier for lower input voltage ranges, input scaling or for differential inputs.

ADC-16 TEMPERATURE INTERFACE

The ADC-16 Temperature Interface has proven to be an extremely reliable industrial grade temperature interface for connection to RS-232, RS-422, RS-485 or USB. It's low cost and proven performance make it the ideal choice for a wide variety of temperature monitoring applications and is for use with all types of computers which provide an RS-232, RS-422, RS-485 or USB connection.

The following temperature interface products are available:
ADC-8/E Analog to Digital Converter...(provides 8 temperature inputs)*
ADC-16/E/F Analog to Digital Converter...(provides 16 temperature inputs)*

Includes (8) precision temperature sensors, (8) trimmer potentiometers (for manual calibration, but not required), resistors, capacitors and voltage reference (if the TE-8 is purchased as a kit, the components must be installed on the ADC-16 or AD-16 cards). The temperature sensors are linear temperature sensing IC's supplied in a TO-92 plastic package. The ADC-16 or AD-16/32 may be ordered with the TE-8 installed by adding the suffix /E or /F (see options) or the ADC-16 may be shipped back to us for installation of the TE-8 at no charge. Temperature range is -40 degrees F to 146 degrees F (-40C to 64C) when used with 8 bit converters or -40 degrees F to 212 degrees F (-40C to 100C) when used with 10 or 12 bit converters.

PLEASE NOTE: The ADC-4, ADC-8 and ADC-16 require a power supply, connecter cable and terminal block to function. Select the power supply and terminal block for your application and the proper cable for your computer. The EX-16, AD-16 and ST-32 expansion cards require the RC-20 ribbon connecter (sold separately) for connection to the A/D converter.

To order the standard ADC-16 analog to digital converter, specify part number ADC-16. The standard ADC-16 will be supplied with an RS-232 serial interface.

To order any of the above options, add the proper suffix to the part number. Any number of options may be included by adding the proper suffix to the part number.

EXAMPLE:
use ADC-8/E ... to order the ADC-8 with port #1 configured for temperature input.
use ADC-4/A/I ... to order the ADC-4 with RS-422 and the optional 8 bit port #2.
use ADC-16/A/E/F ... to order RS-422 with ports #1 and #2 configured for temperature input.
WHAT IS RESOLUTION?

The selection of the analog resolution needed for a particular application is generally based upon the accuracy of the sensor or device connected to the analog input.
An 8 bit analog to digital converter will divide the measurement range into 256 increments.
A 10 bit analog to digital converter will divide the measurement range into 1,024 increments.
An 11 bit analog to digital converter will divide the measurement range into 2,048 increments.
A 12 bit analog to digital converter will divide the measurement range into 4,096 increments.
A 15 bit analog to digital converter will divide the measurement range into 32,768 increments.
A 16 bit analog to digital converter will divide the measurement range into 65,536 increments.
Since most temperature sensors are only accurate to about 1 degree, an 8 bit analog to digital converter will be suitable for measurement of outdoor temperature since the 8 bit converter will allow up to 256 degrees of measurement in one degree increments.

Another example might be a pressure transducer with a working range of 0 to 1000 PSI. An 8 bit converter would present this information in approximately 4 PSI increments... 0 PSI, 4 PSI, 8 PSI, 12 PSI, etc. (1000 divided by 256 equals about 4 PSI). A 10 bit converter will present this information in about 1 PSI increments... 0 PSI, 1 PSI, 2 PSI, 3 PSI, etc. A 12 bit converter will present this information in about quarter PSI increments.
