  • Signal conditioning for most industrial analog or pulse transducer signals
LT Series Transmitter Product Line Overview

Removable screw terminal connections of Laurel transmittersLaureate LT Series DIN rail transmitters & signal conditioners can be interfaced to a wide range of sensors and transducers using one of seven available plug-in signal conditioner boards. The transmitters duplicate the high performance (high accuracy, high read rate) and extensive programmable features of Laureate 1/8 DIN digital panel meters, counters and timers. They utilize the same signal conditioners boards, much of the same firmware, and the same Windows-based instrument setup software. They come in a compact DIN rail mount package with detachable screw-clamp connectors for easy wiring.

Standard LT transmitter features include an RS232 or RS485 serial data interface (isolated, user selectable), a 4-20 mA or 0-10V analog output (isolated), dual 120 mA solid state AC/DC relays (isolated), and a transducer excitation output (isolated, models other than for temperature or AC RMS).

For use on a local area network (LAN), up to 31 LT transmitters can be jumpered for RS485 and be daisy chained to Laurel's LTNET485 DIN rail mounted Ethernet-to-RS485 converter. As an alternative, Laurel's LTE Series Ethernet transmitters can be connected directly to a LAN vian an Ethernet cable. In both cases, setup is easily achieved using Laurel's Node Manager for Ethernet node discovery and setup, and then Instrument Setup Software for setup of each transmitter.
