Transmitter converts serial data to analog output.
Press Release Summary:
Laureate Model TS DIN rail transmitter accepts RS-232 or RS-485 serial data, at rates from 300-19,200 bps, and converts it to isolated, scalable, 4-20 mA, 0-20 mA, or 0-10 V analog output signal. Modbus protocol allows multiple devices to be addressed on same RS485 data line, and Custom ASCII protocol enables retrieval of selected data from long character strings. Two isolated solid state relays, rated 120 mA at 125 Vac or 240 mA at 150 Vdc, are optional for alarm or control.
Original Press Release:
Serial-to-Analog DIN Rail Transmitter Converts Serial Input Data to a Scaled Analog Output
Costa Mesa, CA - Laurel Electronics, Inc. announces the Laureate Model TS, an analog output transmitter which accepts RS-232 or RS-485 serial data and converts it to an isolated, scalable, 4-20 mA, 0-20 mA or 0-10V analog output signal.
A three-terminal connector accepts RS-232 or RS-485 data, as selected via jumpers, at rates from 300 to 19200 bps. The RS-485 interface is compliant with the EIA/TIA-485 standard and supports cable runs up to a mile and multiple addressable devices on the same data line. Either interfaces support both the Modbus protocol and Laurel's simplified Custom ASCII protocol.
The Modbus protocol implementation is fully compliant with Modbus over Serial Line Specification V1.0 (2002) in RTU or ASCII, half duplex (2-wire) operation. The Modbus protocol allows devices by different manufacturers to be addressed on the same RS485 data line.
The Custom ASCII protocol allows the transmitter to retrieve selected data from long character strings. A user can specify character positions, start and stop ASCII characters, how many characters to skip, and how many characters to convert.
Two isolated solid state relays rated 120 mA at 125 Vac or 240 mA at 150 Vdc are optional for alarm or control, and will respond to the received data values. Programmable relay operating modes include operation above or below the setpoint, latching or non-latching, hysteresis mode, and band deviation mode. The Custom ASCII protocol also allows the relays to be actuated by a control character.
The transmitter is housed in a 35 mm DIN rail case, which is only 22.5 mm (0.89") thick. It is powered by 95-240 Vac ±10% or optionally by low voltage 12-34 Vac or 10-48 Vdc. All electrical connections are via detachable screw clamp connectors.
The transmitter's output scaling and relay operation are easily programmed using Laurel's Windows-based Instrument Setup software. This software accommodates all Laureate digital panel meters, counters, timers and transmitters, and can be downloaded at no charge from Laurel's website www.laurels.com.
With normal AC power, the price is $175 without relays and $205 with relays. For specifications, visit www.laurels.com/transmitter-serial2analog.htm.
Founded in 1990, Laurel Electronics, Inc. is a leading U.S. manufacturer of programmable industrial digital panel meters, counters, timers, and DIN rail transmitters.
