DIGITAL WEIGHT TRANSMITTER - WiFi - RS485 - RS232
DESCRIPTION
 WiFi weight transmitter in IP65 polycarbonate box with 3 PG9 cable glands
(on request IP67 version).
170x80x65 mm (four fixing holes Ø4 mm; centre distance
120x60 mm).
 Backlit alphanumeric LCD display, 38x16 mm visible area, two-line by eightdigit (5 mm height).
 Six indicator LED.
 Four-key membrane keyboard for calibration and system configuration.
 Dimensions:
INPUT/OUTPUT AND FIELDBUSES
 WiFi module for wireless connection via integrated web server (to display the
status and to manage the host instrument parameters) or via ModBus RTU,
ASCII Laumas protocols.
 RS485/RS232 serial ports for communication via ModBus RTU protocol,
ASCII Laumas bidirectional or continuous one way transmission.
 4 relay digital outputs controlled by the setpoint values or via protocols or web
 2 PNP digital inputs: status reading via serial communication protocols or web.
 1 load cell input.
MAIN FUNCTIONS
 Connections to:
Re v. 00 de l 12/0 3/2 015
- PC via WiFi/virtual Ethernet port
- PC/PLC via RS485/RS232 (up to 99 instruments with line
repeaters, up to 32 without line repeaters).
- others TLKWF devices and W series Laumas instruments with
OPZW1RADIO optional module via WiFi.
- PC / smartphone / tablet via web browser (point-to-point direct
connection).
- max. 8 load cells in parallel.
 Communication via existing WiFi networks.
 Digital filter to reduce the effects of weight oscillation.
 Theoretical calibration (via keyboard) and real (with sample
weights and the possibility of weight linearization up to 5 points).
 Tare weight zero setting.
 Automatic zero setting at power-on.
 Gross weight zero tracking.
 Semi-automatic tare (net/gross weight) and predetermined tare.
 Semi-automatic zero.
 Displaying the maximum weight value reached (peak).
 Setting of setpoint values and hysteresis.
 Energy saving mode.
WIFI WEB SERVER & SITE
Integrated web site
in combination with WiFi connection for supervision,
management and remote control of the weight transmitter.
The web site is displayed on PC, smatphone and tablet with
standard browsers (Explorer, Safari, Chrome, etc).
