Modbus & Serial Output Transmitter for DC Voltage or Current Input

Laureate TM Series serial output transmitters can be jumpered for two signal levels: RS232 or RS485. Two serial protocols are selectable in software: Modbus or Laurel's Custom ASCII.Modbus protocol operation is fully compliant with the Modbus Over Serial Line Specification V1.0 (2002) for 2-wire, half-duplex connection. This includes RTU or ASCII modes, addressing of up to 32 devices per RS485 line Laurel’s Laurel ASCII protocol allows up to 31 Laureate devices to be addressed on the same RS485 data line. It is simpler than the Modbus protocol and is recommended when all devices are Laureates. It also allows use of Laurel’s data logging software.

Process, Strain Gauge & Potentiometer Follower Input Modbus or Laurel ASCII Protocol Serial I/O Transmitter Scalable for process, strain, pressure, level, flow DIN Rail mounted, digitally programmable.DC Ranges. it provide six voltage ranges and four current ranges, all factory calibrated and jumper selectable. The 200.00 mV and 2.0000 V ranges provide a high input impedance of 1 Gohm to minimize the load on the voltage signal. A 5.000A range measures the IR drop across a built-in 10 mW current shunt. The transmitters can also easily be scaled in software for use with external shunts.Serial Data Output. Transmitters send data as a serial digital signal,are jumper selectable and can each be associated with either the Modbus protocol or Laurel’s simpler Custom ASCII protocol

Dual Pulse Input Channels for Frequency, Rate & Period Modbus or Laurel ASCII Protocol serial output, pulse input frequency, rate and period transmitters accept two independently scalable input channels from a wide range of pulse sources, such as NPN or PNP proximity switches, contact closures, digital logic, magnetic pickups down to 12 mV, or AC voltages to 250 Vac. Input frequencies can range from 0.005 Hz to 1 MHz. Applications include AC line frequency measurement, RPM or speed from proximity switch inputs, and flow rates or totals from turbine flow meter inputs.With a Standard Main Board, the transmitter output can be scaled to track frequency in Hz, rate (such as gallons per minute), or period (inverse of frequency). Square root extraction is standard.

The serial output of Laureate AC phase angle transmitter indicates the lead or lag in degrees from 0º to 360º between two periodic signals having the same period. Phase angle measurement is commonly used with AC power from 50 Hz to 400 Hz. Phase angle needs to be set to zero to synchronize AC generators. It also applies to the triggering of SCRs and Triacs for power control. The phase angle between AC current and voltage determines power factor. The Laureate phase angle meter and transmitter provide exceptionally fast response and high accuracy for low frequencies, such as AC line frequency.

The Laureate TM Series serial output stopwatch transmitter performs all of the functions of the Laureate panel mount stopwatch, except for the display. The data retrieved via serial commands can be the time of individual events (Item #1) which produce start and stop pulses, or accumulated time of multiple events (Item #2). The highest resolution is 0.2 µs, making the transmitter ideal for fast events. The longest timing interval is 999,999 hrs. For long events, the output is updated continuously during timing. There are two primary timing modes:

Duty Cycle Input Modbus or Laurel ASCII Protocol Serial I/O Transmitter Transmits ON or OFF period in percent. DIN Rail mounted, digitally programmable transmitter tracks ON or OFF period as a percentage from 0% to 100% of total period of repetitive pulse trains. The transmitter determines duty cycle by averaging an integral number of periods over a gate time, which is selectable from 10 ms to 199.99 s. The same signal is applied to Channels A and B. The meter divides the average pulse width by the period between pulses and expresses this ratio in percent. A resolution of 1%, 0.1% or 0.01% is selectable. By selecting leading or falling pulse edges, the ON or OFF duty cycle can be transmitted
