Product Description:
Digital input processing is what the ST-121F part of the Crevice Slice Modules product series of the Kollmorgen is mainly designed for. Including 16 digital inputs, this enables it to be used seamlessly in different industrial systems with multiple digital signal channels. It guarantees compatibility with most of the automation processes with a sink type input (positive logic). This module now operates at an on-state voltage of 12−24 VDC (with a 10.2−28.8V operating range) that allows its usage in various commercial applications. This range of input voltage works for a consistent input signal processing in various environmental conditions.
The unit consumes just 45 mA at 5.0 VDC which optimizes power efficiency in low-energy-consuming setups. Input delay is capped at 3 ms for both ON and OFF transitions, ensuring fast response times. The typical software filtering time of 1.5 ms minimizes signal noise and enhances input accuracy and reliability in real-time monitoring. With an operating temperature range from -20°C to +55°C, the device functions across a broad temperature spectrum and is considered ideal for varying industrial conditions. In storage, it can endure temperatures from -40°C to +85°C, making it resilient in harsh environmental settings.
This crevice slice module’s nominal input impedance is 5.1 kΩ, thus provides a reliable and stable input characteristics. Its mechanical size of 12 mm x 99 mm x 70 mm ensures it fits into compact spaces while maintaining a robust build. Additionally, the ST-121F can be easily installed on a DIN rail of 35 mm which allows for straightforward installation in industrial control cabinets. As a result, this product excels in both industrial and building automation solutions, handling inputs from sensors, switches, and other devices to optimize operational efficiency.
