Specifications

MOUNTING A STAND ALONE UNIT...A single interface card may be mounted in an enclosure or on a metal
mounting panel using the MT-1 stand-off mounting hardware. The ADC-16 will attach to the 4 stand-off spacers using
4-40 machine screws (4 mounting holes are provided on the ADC-16). The ADC-16 with an expansion card attached
may be mounted in an enclosure or on a metal mounting panel using the MT-2 stand-off mounting hardware. The
ADC-16/AD-16 (or other combination) will attach to the 4 stand-off spacers using 4-40 machine screws as shown
below (4 mounting holes are provided on the ADC-16 & AD-16). Contact technical support for more information on
mounting panels and custom made distribution boards for use with the ADC-16, STA-16, EX-16, AD-16 and ST-32.
REPAIR SERVICE
In the event that the ADC-16 is damaged from an inadvertent short circuit or other mishap, repair service is available
through us by shipping your ADC-16 to the address on the rear cover of this manual. The charge for minor repair is
$15.00 and takes about 2 business days (not including shipping).
TECHNICAL SUPPORT
Technical support for our products is available by calling [phone]. If a technical adviser is not available, please
leave your name, phone number and a time that you can be reached. Your call will be returned as soon as possible
and within 8 hours. Before contacting technical support be sure that you have your PC and interface hardware
powered up with a telephone at hand. The interfacing hardware (ADC-16, ST-32, etc.) should not be inside an
enclosure and should be immediately accessible. A multimeter should be available for checking voltage levels and
the test software provided with your hardware should be ready to run.

COMMERCIAL USE OF THE ADC-16
When the ADC-16 is to be used in a commercial/industrial environment, additional action must be taken to insure long
term reliability and trouble free operation of the hardware. In general, the most serious threat to the hardware will be
electrical transients (most often caused by electrical storm activity). The following steps are strongly encouraged to
protect the hardware and are listed in the order of highest priority:
(1) Install a voltage surge/spike protector in the 120 volt AC outlet which supplies power to the ADC-16 and to your
hardware. Be sure that the electrical outlet has a third prong electrical ground and that it is correctly wired. Install a
TransZorb on the power input to the ADC-16 (specify the /T option).
(2) Install the ADC-16 (and any expansion cards) in a metal enclosure and ground the enclosure to a reliable earth
ground (an electrical system ground using the third prong on an electrical outlet will usually be sufficient). Connect a
TransZorb from the (-) terminal to the metal enclosure. An in-line ½ amp fast-acting fuse should be installed prior to
the transZorbs (the fuse will blow and prevent damage to the ADC-16 in the event of a major electrical surge). When
the installation site is at higher elevations, in areas that are subject to increased electrical storm activity, the
installation of gas-tube discharge devices and other action may be necessary (contact technical support for more
information).
(3) Order the EX-16 with the /C Opto Isolator option. The opto isolators significantly reduce the possibility of
voltage transients back-feeding to the ADC-16 & EX-16 through the relay output lines.
(4) Power the ADC-16 from a 9 volt regulated DC power supply. The regulation will provide additional protection from
voltage transients. A 9 volt power source will significantly reduce the heat produced by the ADC-16 and will also
reduce the energy consumption of the ADC-16. If the ADC-16 is to be operated continuously in elevated room
temperatures (above 85° F), additional steps should be taken to reduce heating of the ADC-16. Install a larger heat
sink on the ADC-16 regulator and install the ADC-16 in a larger metal enclosure.
RACK MOUNTING
The ADC-16 may be rack mounted with any of the 5" by 7" cards in the CH series card holder racks. The CH-2 will
hold up to (2) of the 5" by 7" cards, the CH-4 will hold up to (4) of the 5" by 7" cards and the CH-8 will hold up to (8) of
the 5" by 7" cards. The interface card (AR-16, ADC-16 or STA-16) should be installed in the top slot of the card holder
rack. The expansion cards (EX-16, ST-32 or AD-16) should be installed in the slots below the interface card. All
ribbon connectors should be plugged in with the ribbon cable pointing up (see diagram). The RC-20 ribbon
connectors are used to connect the ADC-16 to expansion cards and when connecting expansion cards to additional
expansion cards. The use of an extended length RC-20 ribbon cable will be necessary when the AD-16 or ST-32
expansion cards are used with the EX-16 or EX-32 expansion cards (add one inch for each AD-16 or ST-32 card).
