The ST-5111 model, a single-channel high-speed counter by GE Fanuc Emerson, is engineered to cater to demanding measurement tasks. This unit operates with an input voltage of 24 VDC and is designed for an output voltage configuration of either 5 VDC or 28.8 VDC. It requires a current of 6.1 mA when powered at 24 VDC for input and has a maximum output current rating of 0.5 A.

Capable of handling input frequencies up to 1.5 MHz, the counter effectively manages rapid signal changes essential for accurate counting applications. The input duty cycle spans from 10% to 90%, allowing for a range of signal types to be processed. For safety, the design incorporates photocoupler isolation, which separates the input/output circuitry from the logic components, thereby enhancing durability and performance.

In terms of power needs, the ST-5111 consumes 80 mA at 5 VDC for the system while the field power requires an additional 20 mA at 24 VDC. Adjustability is a key feature; it offers an input filter time ranging from 1 microsecond to 10 milliseconds to help refine signal detection. This model features a sink-type output configuration, which is common in many industrial applications.

The physical dimensions of the ST-5111 are about 12 mm in width, 99 mm in height, and 70 mm in depth, while it weighs roughly 70 grams, making it a compact choice for space-limited installations.
