Multifunction LD300 series for incremental encoders: much more than a mere display
Anzeigen, Meß und Regeltechnik, Automatisierung
New LD300 series from Lika Electronic is not only a mere LED display. It can be rightly defined as multifunction and versatile because of the number of benefits it includes. LD300 is a bright and easy-to-read LED display featuring six 15 mm high digits and can show numeric values in the range from -199999 to 999999. It is designed to accept digital quadrature signals from incremental encoders or sensors both rotary and linear having PNP/NPN or Namur characteristics (HTL level +10 + 30V and TTL level +5V). Thus it is mostly used as an either rotational or linear position display, a tachometer / frequency meter, a stopwatch, a start/stop speed display or an event counter. Functions and parameters (such as multiple operation modes, frequencies, resolutions, filters, scaling factor, counting direction etc.) can be set through the three keys located on the front panel. LD300 series can operate at DC/AC multi-voltage power supply (24VDC and 115/230VAC standard, 24/42VAC on request) and further provides +24V/+5V power to supply an external encoder through the auxiliary output. In a customary configuration LD300 display comes with three configurable PNP or NPN inputs in HTL or TTL/CMOS level designed for input frequencies up to 100 kHz (all counter modes) and up to 25 kHz (all other operating modes). It is offered in four configurations to meet the requirements of many different applications. LD300 is a display only version; LD301 further features an adjustable analogue output operating in the range 0 ... +10V or –10V ... +10V according to setting and includes offset and gain functions; LD302 encompasses two optocoupler / transistor digital outputs with adjustable hysteresis for preset function; lastly LD303 boasts a serial RS-232/RS-485 interface for communication with a PC or data output transmission (cyclic or manual).
In addition thanks to the advanced configurations LD300 series can be used to convert signals from digital to analogue; check the encoder status through the monitoring of the digital outputs; transmit values in serial string format.
Among the key features, the easy display scaling to any engineering unit and the selectable linearization with 16 interpolation points and "Teach" function, useful to convert a non-linear input signal into a linear representation and vice versa.
LD300 multifunction display is sealed to IP65 standards in the front side for use in severe industrial environments.
