Laurel LTE20-DCA DC Amp Transmitter


Select Input

Product Description

Laurel LTE20-DCA Series DIN rail transmitters & signal conditioners come with an Ethernet interface (isolated), 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).

Laurel LTE20-DCA transmitters can be interfaced to a wide range of sensors and transducers using one of seven seven available 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 conditioner 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 signal and power.

Laurel LTE20-DCA transmitters can be connected directly to a Local Area Network (LAN) via an Ethernet cable and allow remote readings over the Internet. Modbus TCP and the simpler Laurel ASCII communication protocols are fully supported. Please see our Modbus Communications Manual and our Serial ASCII Communications Manual. Node discovery and transmitter setup are by means of Instrument Setup Software, which is downloadable and free of charge. Additonal Node Manager Software, which is also downloadable and free of charge, provides utilities to configure each node, such as naming the node, entering email addresses for alarm notification and data requests, selecting the node’s time zone for time-stamping of streaming data, setting communication parameters, setting static IP addresses if required, and updating node firmware.
