Product Line Overview

Laureate DIN rail transmitters can be interfaced to a wide range of sensors and transducers with a choice seven plug-in signal conditioners. The transmitters duplicate the high performance (high accuracy, high read rate) and extensive programmable features of 1/8 DIN Laureate digital panel meters, counters and timers. They utilize the same signal conditioners, much of the same firmware, and the same Windows-based instrument setup software, but come in a DIN rail mount package that is only 22.5 mm wide. Standard features include serial communications (isolated), an analog output (isolated), a transducer excitation output (isolated), and dual solid state relays (isolated) for alarm or control. The transmitters are available in three types:

QLS Quad Loop Splitter. Splits one 4-20 mA, 1-5V, 0-5V or 0-10V input into four isolated 4-20 mA output loops, which can share the same ground.
LTS6 Serial-to-Analog transmitter. Converts RS232 or RS485 input to isolated 4-20 mA or 0-10V output.
LTA Series 4-20 mA or 0-10V analog output transmitters. Wide choice of analog or pulse inputs, isolated analog output. Setup is via RS232 and RS485 (standard).
LTM Series Modbus & serial I/O transmitters. Wide choice of analog or pulse inputs, isolated RS232 or RS485 output, half or full duplex. Modbus or Laurel ASCII protocols are user selectable.
