Portable Industrial Wireless Access Points 8 Analog Inputs 15Hz 24
1) Product Overviews :
HTD-WA380 industrial wireless analog collection controller is an
integrated 8 AI controller with industrial WIFI transmission
function. It uses high performance DSP Chip from US TI Inc.and
provides users with multi-scale, high voltage isolation, low drift
and offering smart measurement and control solutions suitable for
widely operating environment temperature range.
HTD-WA380 has 8 differential analog inputs with the range of
4-20mA, 0-5V or 0-10V. The module has 24 bits resolution and up to
115.2Kbps communication speed mainly used in data collection within
industrial field and other distributed fields. With its
user-friendly calibration software, UN-HTD-WA380 is easy for users
to do the zero and full-scale calibration.
UN-HTD-WA380 data collection module uses industrial wireless RS485
communication network. It transmits the analog data to the master
or remote PC-controlled master station after the transfer through
AD. It has dual watchdog security design which includes software
and hardware watchdogs. Module will instantly restart when the
program dashed, HTD-WA355 can solve the inconvenient wiring and
long distance transmission problem as it can communicate with other
I/O controller in different configurations.
UN-HTD-WA industrial wireless I/O controller has four
configurations, which are 2-analog, 4-analog, 6-analog, and
8-analog configuration. The I/0 configuration setting can also be
flexible. Users can close the unused channel through software so
that to increase loop speed.
Even if the RS485 communication network gets fault and the master
computer and controller cannot interlock and communicated, it will
still start up software watchdog. The watchdog is well-designed,
easy to use and can consolidate system security largely.
HTD-WA industrial wireless analog I/O controller use standard
Modbus RTU protocol. Controller will transmit the collected data
through wireless way to control room or upper control machine like
PLC, DCS and other industrial control system machine. HTD series
has been widely used in Siemens, Schneider, Mitsubishi, Omron,
Rockwell and Delta etc.
