Based on the information should not be inferred a certain features or suitability for a particular application. This information does not release the user from the obligation of own judgment and verification. P.P.H. WObit E.K.J. Ober s.c. reserves the right to make changes without prior notice. -
Page 3: Safety And Assembly Rules
Avoid routing control (signal) cables in parallel with or in close vicinity of power and supply cables. • Avoid close vicinity of devices generating high level of electromagnetic and/or pulse interference (high power loads, loads with phase or group power regulation). www.wobit.com.pl User manual -ADT42 – 23.06.2015 – v.1.3 page 3... -
Page 4: Device Description
100.000 of measuring range. ADT42 has multipurpose usage as well at industry as in laboratory, where averaged or precise force (weight) measurement is necessary. Depends on used sensor there is a possibility of measurement of small masses in range as well small weights (grams) as large loads (tons). -
Page 5: Features
Example of application with ADT42 module (silo weight measurement, weight platform) 2.2 Features Signal measurement from four load cells Result conversion into force in N or weight in g, kg, T, f Read out of each channel separately or aggregate of all channels ... -
Page 6: Power Supply
2.4 Power supply ADT42 module can be powered by voltage in range 12 - 24 VDC (max. 36 VDC). Current consumption is max. 150mA (for connected 4 force sensors). While using transistor outputs you should add current consumed on this outputs (max. 0,5A / output). -
Page 7: Insulated Inputs
Tab. 1 Wires color description for sensors from WObit’s offer. CAUTION it is possible, that colors of signals can change. Insulated inputs ADT42 has two opt insulated inputs. They’re activate after giving a voltage 5..24 VDC (minimum 3 V), between input and their common terminal COM by at minimum 10 ms. To keep input inactive, voltage shouldn’t exceed 1 V. -
Page 8: Transducer Configuration
3. Transducer configuration 3.1 Connection by USB USB connector is used for communication with ADT42-PC program which is used for device configuration and measurement data acquisition. After connecting to PC and starting ADT42-PC program there should appear information about connection with ADT42. Installation of USB port drivers isn’t required. -
Page 9: Example Of Configuration
„Reverse the sign” and zeroing channel by pressing „Zero” Filtration of measurement ADT42 has constant averaging filter set in range 0…99 samples and measurement mode „Fast” and „Slow” (2). Bigger value of filtration increases stability of measurements, but also causes slower response for change of signals from sensor. -

ADT42-U – module with voltage output – allowable selection 0-10V ADT42-I – module with current output – allowable selection 0-10mA or 4-20mA Example 1: For aggregate value in range of 0-2000 analog output can change in range from 4mA up... -
Page 11: Configuration Of Transistor Outputs
Example: OUT1 output should be activated in range of measured aggregate value 100 up to 200. 3.3.3 Configuration of RS485 MODBUS This options allows to set MODBUS baudrate in range: 9600, 19200, 38400, 5760, 115200 and set slave address in range 1-247. www.wobit.com.pl User manual -ADT42 – 23.06.2015 – v.1.3 page 11... -
Page 12: Rs485 Modbus Communication
RS485 can be used for communication with PLC driver, HMI panel or other device operating in MODBUS-RTU protocol. RS485 port in ADT42 has no galvanic insulation, so you must provide the same ground potential for ADT42 as for master device. - Page 13 Hi register address 0x0F Lo registry address 0xA1 Lo register address 0xA1 Register 0x00 Hi 0xFF Register 0x00 Hi 0xFF Register 0x00 Lo 0x00 Register 0x00 Lo 0x00 16 bit 16 bit www.wobit.com.pl User manual -ADT42 – 23.06.2015 – v.1.3 page 13...
