ADA-401WP

2.2. DES RIPTION
The use of 1 wire digital sensors eliminates the influence of cable length on the measurement process that usual affects analog
methods of temperature, humidity or pressure measurement and signal processing. Digital sensors transmit the measure value by
data transfer protocol and this simplifies connection wiring of a large number of sensors and improves the detection of faulty
components. Traditionally, it has been difficult to operate 1-WIRE data bus sensors in industrial environments. The solution to this
problem is ADA-401WP addressable measurement module with MODBUS-RTU protocol. The ADA-401WP is robust and modular in
design to operate 1-WIRE sensors in a industrial controller environment.
Using ADA-401WP as a addressable node of 1-WIRE bus lets extend the distance up to 1200m between 1-WIRE devices and PC
with monitoring software e.g. SCADA or other MASTER type device (PLC controller). ADA-401WP is equipped with a screw terminal
blocks for twisted pair connections 1-Wire bus and RS-485, as well as for power. Overvoltage protection on each RS-485 line is made
on the basis of 600W protectors diodes and fuses. To RS485 Bus can be connected 32 devices ADA-401WP.Additional converter
like ADA-I1040 (RS232 to RS485) or ADA-I9140 (USB to RS485) enables monitoring of the modules via RS232 or USB interface of
PC with software as AdaUtil or SCADA.
Using:
- the ADA-4040 repeater to connect another 32 modules and extend RS485 bus up to 1200m,- the ADA-4044H HUB RS485, to
connect up to 128 modules, change RS485 bus topology from linear to star - Each arm of the star can have length 1200 meters
- ETHERNET to RS485 converter (ADA-13040) or Wi-Fi to RS485/422 converter (ADA-14040) you can connect ADA-401WP modules
of any location to monitoring or controlling systems.
The ADA-401WP offers a low power wide input voltage range from an external source of greater than 10V to a maximum of 30V and
can be delivered from power pack (e.g. DR-15-12). The module has built in reverse polarity protection to protection against opposite
polarization of power supply.

2.4. ISOLATION

Fig 2. Isolation structure in ADA-401WP
3. INSTALLATION
This chapter will show how to use and connect ADA-401WP to computer, RS485/RS422 networks, 1-WIRE network and power
supply. In the purpose of minimization of disruptions from environment is being recommended to:
●apply multipair type shielded cables, which shield can be connected to the earthing on one end of the cable,
●arrange signal cables in the distance not shorter than 25 cm from powering cables.
●apply cable for the power of adequate cross-section due to voltage drops for converter powering,
●not supply converter from power circuit device that generates large impulse interference such as transmitters, contactors,
3.1. ASSEMBLING
ADA-401WP enclosure is adapted to assembly on TS-35 (DIN35) rail. To install should be mounted device on the rail, upper part of
the enclosure, then press bottom part to hear characteristic „Click” sound.
3.2. ONNE TION TO OMPUTER
Use a RS232 to RS485 converter (like ADA-I1040), or USB to RS485 (like ADA-I9140) to connect ADA-401WP module to computer.
Fig.3 and Fig.4 (below) shows example connection.
3.3. ONNE TION TO RS485 / RS422 NETWORK
It is possible to connect 32 devices to RS485 network according to EIA-485 standard with total cable length of 1200m. To extend
length of the network or increase the number of device should be used repeater or hub eg. ADA-4040, ADA-4044H.

3.3.1. GND TERMINAL ONNE TION
Connection of GND terminals of RS485/422 interfaces, devices connected to RS485/422 bus, should be done in the case of a
potential difference of the signals grounds on interfaces RS485 / RS422, which prevents proper data transmission.
annot connect to the GND terminal - cables screens, PE circuit of electrical installation, signals grounds of other devices.
3.3.2. LINE TERMINATION
Using Line Termination (terminator) Rt = 120W will reduce electrical reflection in data line at high baud rate. It is not needed below
9600Bd. Should be used Line Termination resistor if the distance is over 1000m @ 9600Bd or 700m @ 19200Bd transmission.
Example connection of Rt (connected to screw terminal block of RS485/422 interface) are shown on Fig. 3 & 4.

In preparation DS2401 circuit.
3.4.4. 1-WIRE NETWORK LIMITATION
The maximum length of 1-WIRE network as layouts producer can be even 400m and the maximum number of sensors can be 500.
However, when building the network, remember that, each sensor is a shortening of 0,5 meters and 100 meters of cable causes
additional capacity load data line 5nF increasing signal distortion.
The real 1-WIRE network length and number of sensors will be less and will depend on:
–type of cables,
–topology connections,
–quality connections,
–interference from external electromagnetic fields.
RE OMMENDATIONS :
–using one type of the cable, we recommend computer twisted cables UTP 4x2x0,5, for 1-WIRE bus,
–1-WIRE network connection in linear topology or use the passive 1-WIRE network splitter DNB-400,
–ending the 1-WIRE network by sensor,
–connecting unused wires and screen cable to PE rail of electrical installation.
–powering ADA-401WP module from individual power supply.
3.5. POWER SUPPLY ONNE TION
The power supply to ADA-401WP module should be DC (regulated) from 10 V to 30V and minimum nominal power should be 3W,
e.g. ZS-12/250 or DR-15-12. Power cable from DC power supplies to device must not be longer than 3m.
Observe the polarity, connect positive (+) of DC power supplies to V+ and negative (-) end to V- terminal. ADA-401WP has the
protection from opposite connection power supply. If after power, on the front panel is not lit green LED PWR, check the power
connection (polarity).

- extension measurement readout time from sensors,
- reducing current value, being in VDD line or DQ, to current value one sensor in time of measurement processing. It is imported in
potentially explosive environments, after connection an intrinsically safe barrier to ADA-401WP.
–Enable write TL and TH registers for DS18xxx: enable this option causes that change of Lo and Hi values in the configuration on
measurement channel is write in TL and TH registers of DS18xxx sensor and readout from these registers. Disable this option
causes that Lo and Hi values setted in the measurement channel configuration are written to ADA-401WP memory and readout
from there.
Options Enable single reading sensors and Enable write TL and TH registers for DS18xxx are available from 2,005 firmware
version and 1.7.1.0 version of ADAUtil.
