| Up/Down Totalizing | |
|---|---|
|
Up/down totalizing is provided by a mode of the Extended counter where pulses are either added or subtracted on Channel A based on a direction input on Channel B. The counter can also be programmed so that counting by Channel A is inhibited by an input on Channel B. |
| Combining Two Totals | |
 |
A+B, A-B and A/B arithmetic functions are available with the Extended counter. A+B sums both totals, while A-B subtracts the outflow total from inflow total. The A/B ratio applied to total helps assure the proper mixing of components. Controller setup and monitoring of the mixing operation are facilitated by optional serial communications. RS485 allows a single data line to handle multiple controllers. |
| Up or Down Counting with Preset | |
 |
A single Laureate dual-channel counter will handle two repetitive fill operations by counting from zero up to a preset, or down from a preset to zero. A dual setpoint relay board is required. |
| Machine Rune Time and Utilization | |
 |
An easy way to measure the run time of machines is to count AC line cycles and scale the total to hours. To display machine utilization or duty cycle in percent, use the Extended counter. Connect Channel A to switched AC and Channel B to the AC line, and have the counter display the A/B ratio with a 100 multiplier. |
| Total and Rate Simultaneously | |
 |
The Extended version of the Laureate dual channel counter can display scaled rate or total for the same channel at the push of a button, and alarm both the rate and total. The Extended version can also do curve linearization, thereby extending the working range and accuracy of flow transducers. |
| System-level Capabilities | |
| The Laureate dual channel totalizer can independently scale, display and alarm two totals, and the totals plus alarm data can be transmitted via RS232 or RS485. The displayed totals can also be transmitted as an isolated 4-20 mA or 0-10V analog output. The Extended version can further display and transmit arithmetic combinations of the two totals. |  |
