Description

The Laureate LTS6 serial input to analog output transmitter accepts RS-232 or RS-485 serial data with the Modbus or Laurel ASCII protocol, or direct ASCII characters, and converts this data to an isolated, scalable 4-20 mA, 0-20 mA or 0-10V analog output signal. The unit fits on a 35 mm DIN rail and is only 22.5 mm (0.89") thick. It is normally powered by AC (85-264 Vac), but can optionally be powered by low voltage AC or DC. All electrical connections are via detachable screw-clamp plugs.

Signal Inputs and Outputs of Laurel TS6 Serial-to-Analog DIN Rail Transmitter
Standard features of the LTS6 include:

  • Analog transmitter output, 16-bit, scalable and isolated. User selectable 4-20 mA, 0-20 mA or 0-10V levels. 16-bit resolution provides an ultra-fine resolution of 0.0015% and accuracy better than 0.02% of output span. Output isolation from signal, power and serial communication grounds is provided by a separate on-board transmitter power supply, thereby eliminating potential problems caused by ground loops. The supply can drive 20 mA into a 500 ohm (or lower) load for 10V compliance, or 10V into 5K ohm (or higher) load for 2 mA compliance.

  • Serial communications, isolated. User selectable RS232 or RS485, half or full duplex, Modbus protocol, Laurel ASCII protocol, or ASCII characters at data rates up to 19200 bps. The RS-232 interface is suitable for short cable runs and point-to-point communications. The RS-485 interface is compliant with the EIA/TIA-485 standard and supports multiple addressable devices on the same data line using the Modbus protocol or Laurel ASCII Protocol. Modbus implementation is fully compliant with Modbus over Serial Line Specification V1.0 (2002) in RTU or ASCII, half-duplex or full-duplex operation, with up to 247 digital addresses. When not using the Modbus protocol, the Laureate serial-to-analog transmitter is able to retrieve digital data from long character strings. You can specify character positions, start and stop ASCII characters, how many characters to skip, and how many characters to process. Slave operation requires connection to a master.

  • Dual solid state relays for control or alarm, isolated. Rated 120 mA at 130 Vac or 170 Vdc.

  • Universal AC power supply for 85-264 Vac.

Easy Transmitter programming is via Laurel's Instrument Setup Software, which runs on a PC under MS Windows. This software can be downloaded from this website at no charge. The required cable from the transmitters to a PC com port is available from Laurel (P/N CBL04).
