LT Series DIN Rail Transmitters, 4-20 mA & RS232/RS485 Serial Data 

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 free Instrument Setup Software. They come in a compact DIN rail mount package with detachable screw-clamp connectors for easy wiring.

The LT series transmitters accessible from this page include a 4-20 mA, 0-20 mA, 0-10V, or -10V to +10V analog output (isolated, user selectable), an RS232 or RS485 serial data interface (isolated, user selectable), and dual 120 mA solid state AC/DC relays (isolated). An isolated 5, 10 or 24 Vdc transducer excitation output is included with all models other than those with a temperature or AC RMS signal conditioner.

For use on a local area network (LAN), up to 30 LT series transmitters can be jumpered for RS485 and be daisy chained to a meter or counter with Laurel's Ethernet-to-RS485 converter board. As an alternative, Laurel's LTE series Ethernet transmitters can be connected directly to a LAN via an Ethernet cable. In both cases, setup is easily achieved using Instrument Setup Software for node discovery and setup of each transmitter.
