SLN-94 Up-Down and Down-Up Pulse Counter with Batching Function

Introducing the SLN-94 Counter: Versatile Pulse Counting and Control Solution

The SLN-94 counter is a powerful device designed for efficient pulse counting and control operations. With its single counting, hold, stop, and clear/start inputs, it offers user-friendly functionality. This counter excels in up-down counting across three decades and boasts a single program register for programming the batcher function.

Equipped with two built-in relay outputs (N.O.), the SLN-94 provides selectable thresholds and versatile modes of operation, making it ideal for controlling external devices. It seamlessly integrates with both NPN and PNP type sensors, thanks to its internal digital debouncing filter, which allows for the use of simple contactors as sensors. Additionally, the built-in sensor supply output (24V DC) can power contactors and various electronic sensors.

Configuring the counter is a breeze, either through the intuitive local keyboard interface or the included S-Config software, accessible via the RS-485 communication port. Take control of your counting needs with the reliable and feature-rich SLN-94 counter.

Product Highlights

The SLN94 counter is a versatile device equipped with various features to facilitate efficient counting operations. It offers single counting, hold, stop, and clear/start inputs, allowing for precise control over the counting process. Designed for up-down counting of pulses in three decades, the counter incorporates a single program register that enables programming of the batcher function. With two built-in relay outputs (N.O.) and selectable thresholds and modes of operation, the SLN94 counter can effectively control external devices according to specific requirements. It supports both NPN and PNP type sensors, thanks to its internal digital denouncing filter, making it compatible with simple contactors used as sensors. Moreover, the counter includes a built-in sensor supply output (24V DC), which can be utilised to power contactors and certain electronic sensors. Configuration options are flexible, allowing users to customise settings using the local keyboard or the free S-Config software via the RS-485 communication port.
