New ASi-5 Counter Modules – Cost-Effective Solutions for a Wide Range of Applications

ASi-5 Counter Modules

What is New About the ASi-5 Counter Modules?

We have extended our range of ASi-5 counter modules with numerous functions, such as measurement of frequency and period duration. Another new feature is the 32-bit value range, which can be selected as an alternative to the fast transmission of 4 independent 16-bit counter values in 1.27 ms. All ASi-5 counter modules work with counter frequencies of up to 250 kHz max.

 

Thanks to their high flexibility – all 4 counter inputs can be configured and parameterized individually – our ASi-5 counter modules can be used to find cost-effective solutions for a wide range of applications. And since you can use IP67 variants directly in the field, you also benefit from all the proven ASi advantages – especially from dramatically reduced wiring complexity.

Advantages at a Glance

Large Data Size and Short Cycle Time

The ASi-5 counter modules optionally transmit 4 independent 16-bit counter values in only 1.27 ms or a 32-bit value range (-2147483647 to 2147483647). They operate with counter frequencies of up to 250 kHz.

 

 

Four Flexibly Usable Counter Inputs

All 4 counter inputs can be configured individually as required. You can also connect pulse counters and encoders (24 V). Functions can be activated directly at the module either via the process data or via hardware inputs. ASi-5 counter modules fit therefore perfectly for a wide range of applications.

Convenient Parameter Assignment

All counter inputs can be easily configured individually via the Bihl+Wiedemann Software Suite.

Modules Directly Usable in the Field

When you opt for our ASi-5 counter modules in IP67, you benefit from the proven ASi advantages in the field: up to 70 % lower wiring costs compared to round cable solutions, reduced installation effort thanks to piercing technology, and freely selectable topology.

Many Flexibly Usable Functions

Thanks to numerous functions and the four individually adjustable counter inputs of the flexible ASi-5 counter modules, you can find cost-effective solutions for a wide range of applications. Various counter functions as well as frequency and period duration measurement enable, for example, simple counting of loose goods, positioning tasks, speed measurement and much more.

The Functions in Detail

Counter

Continuous counter (factory default setting)

In this mode, counting is continuous up to the minimum or maximum value range (optionally 16 or 32 bits) of the counter module.

One-off counter

In this mode, counting takes place once up to a predefined upper limit value (end value) and then stops. When the counter is restarted, it is restarted from a lower limit value (start value).

Periodic counter

In this mode, after reaching the predefined end value, counting is automatically resumed again from the predefined start value via an overflow.

Preset

Apply a predefined value for a specified signal as the current counter reading.

Gating

Lock the counter so that all incoming pulses are ignored. This means that the current counter reading stays until it is enabled again by a trigger.

Capture

Save the current counter reading by transferring it as a latch value to the process data – without interrupted counter function. Optionally, after a capture event, counting can be resumed from a predefined preset value.

Compare

Define a comparison value against which the current counter reading is then consistently checked. A status bit can be set when a predefined condition is met.

Rotation direction

Simply switch between counting forward and counting backward.

 Frequency measurement

One-off frequency

In this mode, the number of pulses is measured once over the specified gate time and then transferred to the process data.

Continuous frequency

In this mode, a new measurement with the same gate time starts directly after the specified gate time has elapsed.

Filtering by gate time

By defining a gate time, all incoming pulses are measured over a specified period of time, and a frequency (Hz) is issued at the end. Outliers can be filtered in this way if desired.

 Cycle time measurement

One-off period duration

In this mode, the period duration is measured once and then transferred to the process data.

Continuous period duration

In this mode, a new measurement starts directly after the end of a measurement. The value is updated after each full period.

Filtering by mean value

Take an average of your period duration measurement through the selection of a specified number of periods. Continuous averaging is performed via the moving average principle.

Adjustable timeout

Set the time that may elapse from the start of the measurement to the first slope or between two slopes before the measurement is defined as invalid.
