Dual solid state relays for control or alarm, isolated.Output isolation from signal and power grounds eliminates potential ground loops.

All selections provide 16-bit (0.0015%) resolution of output span and 0.02% output accuracy of readings from -999,999 to +999,999 counts.

4-20 mA, 0-20 mA, 0-10V or -10V to +10V analog transmitter output, isolated, jumper-selectable and user scalable.

Modbus implementation is fully compliant with Modbus over Serial Line Specification V1.0 (2002) for operation, with up to 247 digital addresses. These commands can be used to set the analag output and the state of the unit's two relays. For details, please or Modbus and Custom ASCII manuals.

Commands via the Modbus RTU, Modbus ASCII or Custom ASCII protocols.

In all cases, it is essential to know know the what ASCII characters are contained in each serial data transmission. The user-selectable 'Remote C' mode allows the number of characters in the data, preceding the data and following the data to be specified. The data to be converted to analog is specified using Laurel's free Instrument Setup Software.

Streaming serial data input, RS232 or RS485.

Depending on the model, it can be powered by AC (85-264 Vac) or DC (10-48 Vdc). The unit is housed in a transmitter case which is only 22.5 mm (0.89') thick and fits on a 35 mm DIN rail. The LTS also accepts serial commands via the Modbus RTU or Laurel Custom ASCII protocols to set the analog output or relay state. Two solid state relays are standard and can respond to readings or to received control characters.

It converts this data to an isolated, scalable 4-20 mA, 0-20 mA, 0-10V or -10V to +10V analog output. * In this program we are reading the analog value fromĪnalog pin A0 converting it and send/print it to the serial monitor.The LTS serial data input, analog output transmitter accepts streaming RS232 or RS485 serial data ASCII strings from an external device, like a scale, at rates up to 9600 baud.

If input voltage from the sensor is from 0-5V then after conversion value will be from 0-1023. Instead of using preset we can use any sensor here. We are using the function for analogRead(A0) converting any analog value to digital. Preset has a three-terminal one is connected to Vcc second to the GND and middle pin to the analog pin A0.Īrduino A to D Conversion Circuit using Preset Here we are connecting a preset to the arduino uno analog pin A0.
