3km wireless distance Industrial wireless access points 4-20mA/0-5V
8 analog output controller
1) Product Overviews :
UN-HTD-WA308 is an industrial wireless functional 8 analog output
controller. It uses high performance DSP Chip from US TI Inc.,
UN-HTD-WA308 provides users with multi-scale, high voltage
isolation, low drift and offering smart measurement and control
solutions suitable for widely operating environment temperature
UN-HTD-WA308 has 8 AO, high accuracy with up to 115.2kbps
communication speed rate. It is mainly used in data collection
within industrial field and other distributed fields. With easy to
operate calibration software, HTD-WA308 is easy for user to do the
zero and full-scale calibration.
UN-HTD-WA308 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, UN-HTD-WA308 can solve the inconvenient wiring and
long distance transmission problem as it can communicate with other
I/O controller in different configuration.
UN-HTD-WA industrial wireless I/O controller has four
configurations like 2 analog,4 analog, 6 analog and 8 analog. 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.
UN-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.
