LTSE Ethernet-to-Analog Converter & Transmitter

Converts Modbus TCP Ethernet data to an isolated, scaled analog output signal.

Ethernet transmitter

Features

  • Receives Ethernet Modbus TCP/IP commands
  • Converts commands to a scaled 4-20 mA or 0-10V analog output
  • Output is isolated from communications and power
  • Analog resolution 0.0015% of span (16 bits), accuracy ±0.02% of span
  • Dual solid state relays for alarm or control, isolated (standard)
  • Universal 85-264 Vac / 90-300 Vdc or 10-48 Vdc / 12-32 Vac power
  • -X extended temperature option from -40°C to 70°C
Description
LTS6 serial to analog transmitter

The LTSE Ethernet input, analog output transmitter converts Ethernet Modbus TCP commands 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 LTSE include:

  • Ethernet serial data input, isolated. Accepts Modbus TCP commands. Modbus implementation is fully compliant with Modbus over Serial Line Specification V1.0 (2002).
  • 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 600 ohm (or lower) load for 12V 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.

Discovery and configuration of Laureate Ethernet transmitters is easily achieved with Laurel's Instrument Setup Software, which runs on a PC under MS Windows and can be downloaded from this website at no charge.

Ordering Guide
Laureate™ LTSE6 Ethernet Input, Analog Output DIN Rail Transmitter
Click on the radio buttons to build a model number with pricing as shown below. Prices are in US dollars and do not include shipping or duty charges (export sales). Please see our explanations and limitations applicable to pricing and online orders. Prices shown are in US Dollars and are Laurel's manufacturer's suggested retail price (MSRP) in the USA. Orders are processed manually, not directly by our shopping cart system. You don't have to supply credit card information when placing an online order.

North American Orders. Laurel does not sell factory-direct in the USA or Canada. Online sales orders are filled through distribution. During the ordering process, you will have the chance to select an authorized Laurel distributor, or you can ask Laurel to refer you to a distributor. The distributor will then contact you to quote shipping, tax and duty (where applicable), and arrange for payment.

International Orders. If your ship-to address indicates that you are outside of the USA or Canada and Laurel has a distributor in your country, we will forward your order to that distributor for follow-up. If Laurel does not have a distributor in your country, we will email you an order acknowledgment and a pro forma invoice which states the product price, shipping charges, and wire transfer information, which includes a $25 bank wire transfer fee.

Questions about your order? Please email your distributor or sales@laurels.com
