Motrona UZ210 Analog to Frequency Signal Converter

The UZ210 is an analog-to-frequency signal converter. This makes it ideal for use as a frequency generator. The input voltage can be variably adjusted using a potentiometer. This makes it possible to generate various frequencies with the UZ210.

The ability to use the UZ210 as a frequency generator is particularly suitable for a simple and quiet setup in laboratory experiments or for maintenance. The major advantage is that it can replace an entire drive unit consisting of a motor, motor controller, and encoder.

These small, cost-effective, yet extremely powerful f/I and f/U converters are designed for control cabinet installation. They convert standard analog signals (V or mA) into an incremental (HTL, RS422/TTL), absolute (SSI), or serial (RS232/RS485) output format. The converters shown below can be quickly and easily mounted on a DIN rail in the control cabinet using snap-on mounting.
