GENERAL DESCRIPTION
T e DAT 3016 device is able to acquire up to 4 analogue input signals. T e data are transmitted wit MODBUS RTU/MODBUS ASCII protocol on t e RS-485
network (RS-232 interface is available).
It is possible to connect on input t ermocouples or voltage signals up to ± 1V . T e Cold Junction compensation for t ermocouples is internally performed.
T e device guarantees ig accuracy and stable measure versus time and temperature.
To ensure t e plant safety, two Watc -Dog timer alarms are provided.
T e isolation between t e parts of circuit removes eventual ground-loop effects, allowing t e use of t e device even in t e eavy environmental conditions.
T e DAT 3016 is in compliance wit t e Directive UL 61010-1 for US market and wit t e Directive CSA C22.2 No 61010-1 for t e Canadian market.
T e device is oused in a roug self-extinguis ing plastic container w ic , t anks to its t in profile of 17.5mm only, allows a ig density mounting on EN-50022
standard DIN rail.
COMMUNICATION PROTOCOLS
T e DAT3016 is designed to work wit t e MODBUS RTU/MODBUS ASCII protocol: standard protocol in field-bus; allows to directly interface DAT3000 series
devices to t e larger part of PLCs and SCADA applications available on t e market.
For t e protocol instructions, refer to t e User Guide of t e device.
USER INSTRUCTIONS
Before to install t e device, please read t e “Installation Instruction” section.
If t e module configuration is unknown, wit device powered off, connect t e INIT terminal to t e GND terminal (ground), at t e next power on t e device will be
auto-configured in t e default settings (refer to t e User Guide of t e device).
Connect power supply, serial bus and analogue inputs as s own in t e “Wiring” section.
T e “PWR” LED state depends on t e working condition of t e device: see t e "Lig t Signalling" section to verify t e device working state.
To perform configuration and calibration operations, read t e instructions in t e User Guide of t e device.
To simplify andling or replacing of t e device, it is possible to remove t e wired terminals even wit t e device powered.

INSTALLATION INSTRUCTIONS
T e DAT 3016 is suitable for fitting to DIN rails in t e vertical position.
For optimum operation and long life follow t ese instructions:
When the devices are installed side by side it may be necessary to
separate them by at least mm in the following case:
- If panel temperature exceeds 45°C and at least one of t e overload
conditions exist.
Make sure t at sufficient air flow is provided for t e device avoiding to place
raceways or ot er objects w ic could obstruct t e ventilation slits. Moreover
it is suggested to avoid t at devices are mounted above appliances
generating eat; t eir ideal place s ould be in t e lower part of t e panel.
Install t e device in a place wit out vibrations.
Moreover it is suggested to avoid routing conductors near power signal
cables (motors, induction ovens, inverters etc...) and to use s ielded cable
for connecting signals.
