-Accepts Ethernet or RS232 / RS485 serial data, half or full duplex, isolated
-Supports Modbus RTU, Modbus ASCII, or Laurel ASCII protocols
-Able to retrieve data from long character strings
-Serial data rates from 300 to 19,200 bps
-Analog transmitter output, isolated
-Analog resolution 0.0015% of span (16 bits), accuracy ±0.02% of span
-Dual solid state relays for alarm or control, isolated
-Universal AC power, 85-264 Vac, or low voltage power, 10-48 Vdc or 12-32 Vac
The LTS6 serial data input, analog output transmitter accepts Ethernet, RS232 or RS485 serial data using the Modbus protocol, 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. The unit is housed in transmitter case which is only 22.5 mm (0.89") thick and fits on a 35 mm DIN rail. It is normally powered by AC (85-264 Vac), but can optionally be powered by low voltage AC or DC.
Standard features of the LTS6 include:
Serial data input, isolated. Ethernet or user-selectable RS232 or RS485. The Modbus protocol, Laurel ASCII protocol, or ASCII characters are supported at data rates to 19200 bps. 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. Using the Laurel ASCII protocol, the serial-to-analog converter 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.
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.
Dual solid state relays for control or alarm, isolated. Rated 120 mA at 140 Vac or 180 Vdc.
Universal AC power, 85-264 Vac, or low voltage power, 10-48 Vdc or 12-32 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).
