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, and converts it 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.
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 an 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 or
Laurel ASCII protocol, 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.
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.
- 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). |
