MLTE-FR | Ethernet & 4-20 mA Output | Average Time of Periodic Events | DIN Rail Transmitter

The Micron Meter Time interval transmitter can transmit pulse width or time delay between individual pulses to a resolution of 0.2 µs for periodic events. It can also transmit average pulse width or average time delay between multiple pulses.

Time interval is measured between inputs on channels A and B. Timing starts when a pulse is applied to Channel A (selectable positive or negative edge), and ends when a pulse is applied to Channel B (selectable positive or negative edge). In case of a single pulsed signal, the A and B inputs can be tied together. A positive or negative slope may be selected to start timing, and the opposite slope must be selected to stop timing. Timing is achieved by counting 5.5 MHz clock pulses. Multiple integral time intervals are averaged over a gate time which is selectable from 10 ms to 199.99 s and also controls the maximum output rate.

The dual-channel signal conditioner used for pulse detection accepts inputs from proximity switches with PNP or NPN output, TTL or CMOS logic, magnetic pickups, contact closures, and other signals from 12 mV to 250 Vac. Jumper selections provide optimum operation for different sensor types and noise conditions. A built-in 5V, 10V or 24V dc excitation supply can power proximity switches and other sensors, and eliminate the need for an external power supply.

Standard features of Micron MLTE transmitters include:

• Ethernet I/O, isolated. Supported protocols are Modbus RTU and ASCII (tunneled via Modbus TCP) and Custom ASCII. The latter is simpler than the Modbus protocol and is recommended when all devices are Micron units. Note that RS232 or RS485 data I/O in lieu of Ethernet is provided by MLT Series transmitters
• 4-20 mA, 0-20 mA or 0-10V analog transmitter output, isolated, jumper-selectable and user scalable. All selections provide 16-bit (0.0015%) resolution of output span and 0.02% output accuracy of a reading from -99,999 to +99,999 counts that is also transmitted digitally. Output isolation from signal and power grounds eliminates potential ground loop problems. The supply can drive 20 mA into a 500 ohm (or lower) load for 10V compliance, or 10V into a 5K ohm (or higher) load for 2 mA compliance.
• Dual solid state relays, isolated. Available for local alarm or control. Rated 120 mA at 130 Vac or 180 Vdc.
• Universal 85-264 Vac power. Low-voltage 10-48 Vdc or 12-32 Vac power is optional.

Discovery and configuration of the Ethernet Nodes is easily achieved with the Node Manager Software, and the discovered transmitters can then be programmed using the  Instrument Setup Software. Both softwares run on a PC under MS Windows and can be downloaded from this website at no charge.
