Iniven IAFT-30ADSP, Инструкция по эксплуатации

Страница: 2 / 45

DESCRIPTION
The IAFT-30ADSP is a compact single analog transmitter for use in telemetry systems. Inside of the chassis are three
different modules mounted to the common terminal board in the back of the unit. These modules include: IT-98
Programmable Transmitter, IP-98 Power Supply, and I/O 40T Analog I/O Module.
IT-98DSP
Transmitter Module
FEATURES
•
Optical or voltage keying inputs
provided on each unit.
•
Front panel level adjustment
•
DIP switch programmable
•
Modular cost saving design
•
12 Year Warranty
DESCRIPTION
The IT-98DSP is a programmable
frequency shift keyed (FSK) tone
transmitter intended for use on the
transmitting end of a communication
channel in supervisory control,
telemetry and data transmission
applications. It may be used over
voice grade circuits including carrier,
wire line, fiber optics, and
microwave.
Each transmitter module is field
programmable for a specific center
frequency, frequency shift
(bandwidth/baud rate) and mode of
operation via DIP switches.
Operational modes include two
frequency (2F) or three frequency
(3F) keying, carrier on/off (Request-
To-Send, RTS) and when
communicating with a similarly
equipped receiver, inverted keying
and flasher (keying of both mark and
space simultaneously).
IP-98
Power Supply Module
FEATURES
•
Wide Range of Input Voltages
•
5000 Vdc Isolation
•
Modular cost saving design
•
12 Year Warranty
DESCRIPTION
The IP-98 and IP-98-1U are a series
of Regulated Switching Power
Supplies for use within the 3U, 1U,
and compact style chassis.
The IP-98 is available in a wide
range of input voltages; 115 Vac,
125 Vdc, 48 Vdc, 24Vdc, and 12 Vdc
each providing reg5 V, +15 V
& -15 Vdc outputs. The IP-98-
115Vac, IP-98-125Vdc, IP-98-48Vdc,
and IP-98-24Vdc provide 55 Watts of
power standard, while the IP-98-
12Vdc and aIl IP-98-1 U versions
used in the 1U chassis deliver 20
Watts of power.
All supplies except the 12 Vdc units
have 5000 Vdc isolation from input to
output and meet both SWC
Standards ANSI/IEEE C37.90.1978
& C37.90a-1974.
I/O 40T
Analog I/O Module
FEATURES
•
Uni-polar or bi-polar I/O’s
•
Wide range of I/O’s
•
High accuracy & stability
•
Differential input for ground loop
noise rejection
•
Form C relay output
•
12 year warranty
DESCRIPTION
The I/O 40T is an accurate and
stable voltage (or current) to
frequency converters. The I/O 40T
when used in conjunction with
INIVEN’s 98 Series FSK transmitter,
is the transmitting side of an analog
telemetry system.
Various inputs to the unit can be
accommodated. Bi-polar and uni-
polar voltage or current inputs can be
accepted.
The output of the I/O module is a
square wave which modulates an
FSK tone transmitter alternately
between mark and space
frequencies at a rate within a 5-30Hz
range. Standard ranges are 5-25Hz,
10-30Hz and 18-30Hz.
