Analog I/O Modules Engineering Information and Selection Chart
ANALOGI/OMODULES
12-bit value that is right justified and packed in
a 16-bit word that represents the equivalent
analog value sensed.
Analogoutputmodulesareusedinproportional
control of devices such as valves, motors, and
heaters. Analog input modules are used in data
gatheringandproportionalcontrolapplications.
Start Pulse: High for 6.4 µS Min., then low
for 3.2 µS
Data Packet: Each bit is 12.8 µS long.
High for first 3.2 µS of the bit.
Middle 6.4 µS determines the value of the
data bit (High = 1, Low = 0).
®
OpenLine thermocouple inputs linearize the
thermocouple reading and returns degrees to
the controller.
All modules are potted for industrial
environments. They operate under high
vibration (IEC68-2-6; 0.15 mm/sec2 at 10-
150Hz) mechanical shock (IEC68-2-27; 11
mS,sinusoidal30gS)andhighrelativehumidity
(IEC68-2-3; 5-95% non-condensing). They
feature a high level of noise immunity and
accuracy. All models provide isolation from
field to logic, field to power supply and module
to module.
Low for last 3.2 µS of the bit.
Stop Pulse: Low for 500 µS minimum
Times shown are 10%, except minimums.
SERIAL DATA FORMAT**
Openline® Analog Output
For analog output modules, the output of these
modules is zero scale on power up, then it is
the analog equivalent of the 12-bit value sent
to the module over the communication lines.
G5 Analog Input
G5voltageorcurrentinputmodulesareactually
frequency converters. The input to these
modules is a signal from a sensor. The output
from these modules is a squarewave whose
frequency varies linearly from 14.4 to 72 KHz
and is proportional to the input signal. The
controller must be able to measure this
frequency and convert it back to a signal level.
G5 Analog Output
The output (voltage or current level) of these
modules varies proportionally to the 12-bit
serial data string sent to them by a control
circuit. The data string is typically 213.2 µSec.
long as detailed in Figure 1. Once a data string
is received, the output is set and remains
constant until another data string is sent.
Therefore, the output level of the module could
be changed almost 4700 times a second.
OpenLine® Analog
OpenLine® analog modules communicate
serially with the controller. Each module has a
separatetransmitandreceivelinethatoperates
at 115,200 baud with no parity bits, 8 data bits,
and 1 stop bit (115.2K,N,8,1). The command
structure and responses for all modules are
detailed in Bulletin No. 743. Each module has
a microcontroller and non-volatile serial
EEPROM memory. The calibration data is
stored within the EEPROM, and may be
changed using the appropriate commands
and the 70L-PROG field calibration unit. The
software provided with the calibration unit
communicates with the modules through the
serial port of a PC. Calibration equipment is not
provided.
G5 thermocouple modules pass through the
thermocouple reading and do not linearize the
signal. Linearization must take place within the
controller.
For more information on programming Grayhill
analog output modules, request a copy of
Bulletin No. 581.
AgencyApprovals
OpenLine® analog modules are EN50082-2
and EN50081-2 compliant and meet the
requirements of 89/336/EEC EMC directive.
They are also EN60950 (61010-1) compliant.
Meetingtheserequirementsallowsthemodules
to bear the CE mark. Additionally, the modules
are CSA certified to CSA 22.2 No. 14-95M and
CSA 22.2 No. 213-M1987 Class I, Div. 2
Groups A, B, C and D and are UL recognized
to UL 508.
