9-3. Analog IN/OUT [ANA]
ANA is an optional converter board with two channels of analog input (current or
voltage), three channels of analog output (current), and one channel of pulse input.
・
Analog input function
This option converts the analog external signal to belt speed and target value, and the
converted signal is used for comparison and as a parameter for measurement values.
Input range:
4-20 mA (current input)
0-10 V (voltage input)
Each channel can be independently configured.
Analog input data is calibrated using [AI ZERO SET] and [AI FULL SCALE SET]
parameters. Analog input terminals are electrically isolated form the internal circuit
using photo-coupler. It has 16-bit resolution and each channel is capable of 30
conversions per second. This input is capable of accepting over-range input (approx.
±5% FS).
* Signal type for each channel (current/voltage) is factory-configured (indicated in the
label attached near the connector).
・ Analog output function
This converter option outputs analog signal (4-20 mA) corresponding to the F805AT-
BC reading. Zero (4mA) and full-span (20mA) of this signal is defined using [AO
ZERO OUTPUT WEIGHT] and [AO FULL SCALE VALUE] parameters, and
arbitrary digital value between them can be obtained as an analog signal.
Output terminals and internal circuit are electrically isolated using photo-couplers. It
has 16-bit resolution and each channel is capable of 50 conversions per second. This
option is capable of over-range output up to approx. ±5% of FS.
・
Pulse input function
Using this option, external pulse train is representing the belt speed which is used as
parameters for types of comparisons and readings.
