Series SD 340 provides a new generation of industrial speed meters with unprecedented options for measuring and control of speeds, speed ratios, differential speeds and other calculations of two speeds. These are some of the highlight features of the new products:
• Two fully independent impulse inputs for sensors or encoders. It is possible to use simple transducers like proximity switches or photocells. The units however are able to also evaluate full quadrature signals of encoders (A, /A, B, /B)
• Operating modes for measuring of two individual speeds or combinations of two speeds like ratios, products, differential speed or percentaged difference, including full consideration of the directions of rotation of both channels
• Extremely wide frequency range from 0.01 Hz up to 1 MHz (each input channel)
• Four programmable presets and switching outputs with very fast response
(1 kHz)
• Programmable characteristics like self-sustaining of outputs, start-up-delay, digital filtering functions, linearization and more.
• Serial interface (RS232, RS485) and high-speed analogue output (model SA) for use of the measuring results with superior control systems
The units are available in a standard housing with dimensions 96 x 48 mm (3.78 x 1.89 ”) and operate from a power supply with either 24 VDC or 24 VAC
