3.2 ADAM-4016 Analog Input/Output Module
A strain gauge input module uses a microprocessor-controlled integrating
A/D converter to convert sensor voltage or current signals into digital data
for load cell and stress measurement. The digital data is then translated into
either engineering units, twos complement hexadecimal format or percent-
age of full-scale range (FSR) according to the module's configuration.
When prompted by the host computer, the data is sent through a standard
RS-485 interface.
The strain gauge input module offers signal conditioning, A/D conversion,
ranging, and RS-485 digital communication functions. They protect your
equipment from ground loops and power surges by providing opto-
isolation of the A/D input and transformer based isolation up to 3000 V .
DC
Excitation Voltage Ouput
A strain gauge input module can supply single channel voltage output for
excitation. The module receives digital input from the host computer. The
format of the data is engineering units. It then uses its microprocessor-
controlled D/A converter to convert the digital data into output signals.
Strain gauge input modules protect your equipment from ground loops and
power surges by providing opto-isolation of the D/A output and
transformer-based isolation up to 3000 V .
DC
Digital Outputs
A strain gauge input module also contains 4 digital outputs. Outputs are
open-collector transistor switches that may be controlled by the host
computer. They can control solid-state relays which in turn may control
heaters, pumps, and other electrical equipment.
