Micron Meters- Serially Driven 6-Digit

Description

Micron Remote Displays or Serial Input Meters accept RS232, RS485, Modbus RS485 or USB data from computers, programmable controllers, Micron instruments, or other devices with a serial data output. They can also provide relay closures and an analog output based on the received serial data. They blend in with 1/8 DIN Micron digital panel meters, counters and timers to provide a numeric display from -999,999 to +999,999.

Use with Micron Instruments. All Micron meters, counters and timers allow the display of the sending unit to be duplicated by a Micron remote display. The simultaneous display of multiple parameters using multiple remote displays is possible if the sending unit is a Micron counter equipped with an FR (frequency) or VF (voltage-to-frequency) signal conditioner board. While the sending counter can only display one selected parameter at a time (such as rate for channel A), up to four parameters can be transmitted in the serial data (such as rate A, rate B, ratio A/B and peak). A remote display can be set up to display any of the transmitted items. For example, a Micron Batch Controller can show the current batch total, while remote displays show rate, peak rate, and either grand total or number of batches. An indicator light shows which item has been chosen for display.

A serial communications board is required. Choices are RS232 with an RJ11 connector, RS485 with dual RJ11 connectors for daisy chaining, Modbus RS485 with dual RJ45 connectors for daisy chaining, USB, and USB for connection to a PC plus an RJ11 connector to an RS485 network. Three serial protocols are user-selectable for all serial interface boards: Modbus RTU, Modbus ASCII, and Micron ASCII. The Modbus protocol allows devices by different manufacturers to share the same data line, but the Micron protocol is simpler and is recommended when all devices on the line are Microns.

Isolated Analog Output Option. A Micron remote display can be equipped with an optional 16-bit isolated analog output board with a 4-20 mA, 0-20 mA, 0-10 V or -10 to +10V output to serve as a low-cost and highly accurate digital-to-analog converter or transmitter.

Alarm & Setpoint Control Options. A Micron remote display can be equipped with an optional relay output board with dual 8A contact relays or dual opto-isolated AC/DC solid state relays to provide remote alarm and setpoint control capability. The relays can respond to the transmitted values or to any of 8 serially transmitted control characters. The control characters can be generated by a Micron meter, counter or timer, thereby assuring that the local and remote alarm points are identical.
