Voltage to RS232 converter
DAT3017V RS232
The device DAT 3017-I is able to acquire up to 8 analogue input signals. The data are transmitted with MODBUS RTU/MODBUS ASCII protocol on the RS-232 network (RS-485 interface is available). It is possible to connect input current signals up to ± 20 mA. The device guarantees high accuracy and stable measurement over time and temperature.
To ensure plant safety, two Watch-Dog timer alarms are provided. The isolation between the parts of the circuit removes any ground-loop effects, allowing the use of the device even in harsh environmental conditions.
The DAT 3017-I complies with the UL 61010-1 directive for the US market and the CSA C22.2 No 61010-1 directive for the Canadian market. The device is housed in a rugged, self-extinguishing plastic container with a thin profile of only 17.5mm, allowing high-density mounting on an EN-50022 standard DIN rail.
The DAT 3017-I is designed to work with the MODBUS RTU/MODBUS ASCII protocol, a standard protocol in field-bus systems. This allows direct interfacing of DAT3000 series devices with most PLCs and SCADA applications available on the market. For protocol instructions, refer to the User Guide of the device.
Before installing the device, please read the “Installation Instruction” section. If the module configuration is unknown, with the device powered off, connect the INIT terminal to the GND terminal (ground). At the next power-on, the device will auto-configure to the default settings (refer to the User Guide of the device).
Connect the power supply, serial bus, and analogue inputs as shown in the “Wiring” section. The “PWR” LED state depends on the working condition of the device: see the "Light Signalling" section to verify the device working state.
To perform configuration and calibration operations, read the instructions in the User Guide of the device. To simplify handling or replacing the device, it is possible to remove the wired terminals even with the device powered.
